kinetic_cafe_error provides an API-smart error base class and a DSL for defining errors. Under Rails, it also provides a controller concern (KineticCafe::ErrorHandler) that has a useful implementation of +rescue_from+ to handle KineticCafe::Error types. Exceptions in a hierarchy can be handled in a uniform manner, including getting an I18n translation message with parameters, standard status values, and meaningful JSON representations that can be used to establish a standard error representations across both clients and servers.

Small class to simplify the writing and handling of GraphQL queries and mutations for the Shopify Admin API. Comes with built-in retry, pagination, error handling, and more!

There is great benefit in adopting a standard library of exceptions. Projects and libraries can all assume the same set of exception classes will be raised and caught using the built in language rescue keyword which filters on class. It becomes especially powerful for building API's, where specific exception classes can be made to return specific HTTP status codes. This libary also provides helper bang-methods eg. unauthorised! for raising these standard kinds of errors

# Kaffe Framework This is a minimalistic webframework inspired by sinatra and rails. ## Basic usage The idea is to use be able to create modular applications and forward requests between them. class Blog < Kaffe::Base use Rack::CommonLogger get '/?' do "Hello From Blog" end end class Admin < Kaffe::Base get '/login' do ... Login logics ... end error 400..500 do |code, message| .. show pretty error message .. end end class MyApp < Kaffe::Base route '/blog', Blog route '/admin', Admin end run MyApp ## API overview

A lightweight Ruby gem that enables Rails applications to dynamically execute command objects using convention over configuration. Automatically transforms request paths into Ruby class constants, allowing controllers to dispatch commands based on routes and parameters. Features the optional CommandCallable module for standardized command interfaces with built-in success/failure tracking and error handling. Perfect for clean, maintainable Rails APIs with RESTful route-to-command mapping. Only depends on ActiveSupport for reliable camelization.

TypedCache is a Ruby caching library designed to eliminate common caching pitfalls by providing a monadic, type-safe API that makes cache operations explicit and predictable. Cache interactions are first-class operations with comprehensive error handling and transparent state management. The library supports wrapping other caching libraries via custom backends and ActiveSupport::Cache is supported out of the box.

# COM # COM is an object-oriented wrapper around WIN32OLE. COM makes it easy to add behavior to WIN32OLE objects, making them easier to work with from Ruby. ## Usage ## Using COM is rather straightforward. There’s basically four concepts to keep track of: 1. COM objects 2. Instantiable COM objects 3. COM events 4. COM errors Let’s look at each concept separately, using the following example as a base. module Word end class Word::Application < COM::Instantiable def without_interaction with_properties('displayalerts' => Word::WdAlertsNone){ yield } end def documents Word::Documents.new(com.documents) end def quit(saving = Word::WdDoNotSaveChanges, *args) com.quit saving, *args end end ### COM Objects ### A COM::Object is a wrapper around a COM object. It provides error specialization, which is discussed later and a few utility methods. You typically use it to wrap COM objects that are returned by COM methods. If we take the example given in the introduction, Word::Documents is a good candidate: class Word::Documents < COM::Object DefaultOpenOptions = { 'confirmconversions' => false, 'readonly' => true, 'addtorecentfiles' => false, 'visible' => false }.freeze def open(path, options = {}) options = DefaultOpenOptions.merge(options) options['filename'] = Pathname(path).to_com Word::Document.new(com.open(options)) end end Here we override the #open method to be a bit easier to use, providing sane defaults for COM interaction. Worth noting is the use of the #com method to access the actual COM object to invoke the #open method on it. Also note that Word::Document is also a COM::Object. COM::Object provides a convenience method called #with_properties, which is used in the #without_interaction method above. It lets you set properties on the COM::Object during the duration of a block, restoring them after it exits (successfully or with an error). ### Instantiable COM Objects ### Instantiable COM objects are COM objects that we can connect to and that can be created. The Word::Application object can, for example, be created. Instantiable COM objects should inherit from COM::Instantiable. Instantiable COM objects can be told what program ID to use, whether or not to allow connecting to an already running object, and to load its associated constants upon creation. The program ID is used to determine what instantiable COM object to connect to. By default the name of the COM::Instantiable class’ name is used, taking the last two double-colon-separated components and joining them with a dot. For Word::Application, the program ID is “Word.Application”. The program ID can be set by using the .program_id method: class IDontCare::ForConventions < COM::Instantiable program_id 'Word.Application' end The program ID can be accessed with the same method: Word::Application.program_id # ⇒ 'Word.Application' Connecting to an already running COM object is not done by default, but is sometimes desirable: the COM object might take a long time to create, or some common state needs to be accessed. If the default for a certain instantiable COM object should be to connect, this can be done using the .connect method: class Word::Application < COM::Instantiable connect end If no running COM object is available, then a new COM object will be created in its stead. Whether or not a class uses the connection method can be queried with the .connect? method: Word::Application.connect? # ⇒ true Whether or not to load constants associated with an instantiable COM object is set with the .constants method: class Word::Application < COM::Instantiable constants true end and can similarly be checked: Word::Application.constants? # ⇒ true Constants are loaded by default. When an instance of the instantiable COM object is created, a check is run to see if constants should be loaded and whether or not they already have been loaded. If they should be loaded and they haven’t already been loaded, they’re, you guessed it, loaded. The constants are added to the module containing the COM::Instantiable. Thus, for Word::Application, the Word module will contain all the constants. Whether or not the constants have already been loaded can be checked with .constants_loaded?: Word::Application.constants_loaded # ⇒ false That concludes the class-level methods. Let’s begin with the #connected? method among the instance-level methods. This method queries whether or not this instance connected to an already running COM object: Word::Application.new.connected? # ⇒ false This can be very important in determining how shutdown of a COM object should be done. If you connected to an already COM object it might be foolish to shut it down if someone else is using it. The #initialize method takes a couple of options: * connect: whether or not to connect to a running instance * constants: whether or not to load constants These options will, when given, override the class-level defaults. ### Events ### COM events are easily dealt with: class Word::Application < COM::Instantiable def initialize(options = {}) super @events = COM::Events.new(com, 'ApplicationEvents', 'OnQuit') end def quit(saving = Word::WdDoNotSaveChanges, *args) @events.observe('OnQuit', proc{ com.quit saving, *args }) do yield if block_given? end end end To tell you the truth this API sucks and will most likely be rewritten. The reason that it is the way it is is that WIN32OLE, which COM wraps, sucks. It’s event API is horrid and the implementation is buggy. It will keep every registered event block in memory for ever, freeing neither the blocks nor the COM objects that yield the events. ### Errors ### All errors generated by COM methods descend from COM::Error, except for those cases where a Ruby error already exists. The following HRESULT error codes are turned into Ruby errors: HRESULT Error Code | Error Class -------------------|------------ 0x80004001 | NotImplementedError 0x80020005 | TypeError 0x80020006 | NoMethodError 0x8002000e | ArgumentError 0x800401e4 | ArgumentError There are also a couple of other HRESULT error codes that are turned into more specific errors than COM::Error: HRESULT Error Code | Error Class -------------------|------------ 0x80020003 | MemberNotFoundError 0x800401e3 | OperationUnavailableError Finally, when a method results in any other error, a COM::MethodInvocationError will be raised, which can be queried for the specifics, specifically #message, #method, #server, #code, #hresult_code, and #hresult_message. ### Pathname ### The Pathname object receives an additional method, #to_com. This method is useful for when you want to pass a Pathname object to a COM method. Simply call #to_com to turn it into a String of the right encoding for COM: Word::Application.new.documents.open(Pathname('a.docx').to_com) # ⇒ Word::Document ## Installation ## Install COM with % gem install com ## License ## You may use, copy and redistribute this library under the same [terms][1] as Ruby itself.

This documentation describes LaunchDarkly's REST API. To access the complete OpenAPI spec directly, use [Get OpenAPI spec](https://launchdarkly.com/docs/api/other/get-openapi-spec). To learn how to use LaunchDarkly using the user interface (UI) instead, read our [product documentation](https://launchdarkly.com/docs/home). ## Authentication LaunchDarkly's REST API uses the HTTPS protocol with a minimum TLS version of 1.2. All REST API resources are authenticated with either [personal or service access tokens](https://launchdarkly.com/docs/home/account/api), or session cookies. Other authentication mechanisms are not supported. You can manage personal access tokens on your [**Authorization**](https://app.launchdarkly.com/settings/authorization) page in the LaunchDarkly UI. LaunchDarkly also has SDK keys, mobile keys, and client-side IDs that are used by our server-side SDKs, mobile SDKs, and JavaScript-based SDKs, respectively. **These keys cannot be used to access our REST API**. These keys are environment-specific, and can only perform read-only operations such as fetching feature flag settings. | Auth mechanism | Allowed resources | Use cases | | ----------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | -------------------------------------------------- | | [Personal or service access tokens](https://launchdarkly.com/docs/home/account/api) | Can be customized on a per-token basis | Building scripts, custom integrations, data export. | | SDK keys | Can only access read-only resources specific to server-side SDKs. Restricted to a single environment. | Server-side SDKs | | Mobile keys | Can only access read-only resources specific to mobile SDKs, and only for flags marked available to mobile keys. Restricted to a single environment. | Mobile SDKs | | Client-side ID | Can only access read-only resources specific to JavaScript-based client-side SDKs, and only for flags marked available to client-side. Restricted to a single environment. | Client-side JavaScript | > #### Keep your access tokens and SDK keys private > > Access tokens should _never_ be exposed in untrusted contexts. Never put an access token in client-side JavaScript, or embed it in a mobile application. LaunchDarkly has special mobile keys that you can embed in mobile apps. If you accidentally expose an access token or SDK key, you can reset it from your [**Authorization**](https://app.launchdarkly.com/settings/authorization) page. > > The client-side ID is safe to embed in untrusted contexts. It's designed for use in client-side JavaScript. ### Authentication using request header The preferred way to authenticate with the API is by adding an `Authorization` header containing your access token to your requests. The value of the `Authorization` header must be your access token. Manage personal access tokens from the [**Authorization**](https://app.launchdarkly.com/settings/authorization) page. ### Authentication using session cookie For testing purposes, you can make API calls directly from your web browser. If you are logged in to the LaunchDarkly application, the API will use your existing session to authenticate calls. Depending on the permissions granted as part of your [role](https://launchdarkly.com/docs/home/account/roles), you may not have permission to perform some API calls. You will receive a `401` response code in that case. > ### Modifying the Origin header causes an error > > LaunchDarkly validates that the Origin header for any API request authenticated by a session cookie matches the expected Origin header. The expected Origin header is `https://app.launchdarkly.com`. > > If the Origin header does not match what's expected, LaunchDarkly returns an error. This error can prevent the LaunchDarkly app from working correctly. > > Any browser extension that intentionally changes the Origin header can cause this problem. For example, the `Allow-Control-Allow-Origin: *` Chrome extension changes the Origin header to `http://evil.com` and causes the app to fail. > > To prevent this error, do not modify your Origin header. > > LaunchDarkly does not require origin matching when authenticating with an access token, so this issue does not affect normal API usage. ## Representations All resources expect and return JSON response bodies. Error responses also send a JSON body. To learn more about the error format of the API, read [Errors](https://launchdarkly.com/docs/api#errors). In practice this means that you always get a response with a `Content-Type` header set to `application/json`. In addition, request bodies for `PATCH`, `POST`, and `PUT` requests must be encoded as JSON with a `Content-Type` header set to `application/json`. ### Summary and detailed representations When you fetch a list of resources, the response includes only the most important attributes of each resource. This is a _summary representation_ of the resource. When you fetch an individual resource, such as a single feature flag, you receive a _detailed representation_ of the resource. The best way to find a detailed representation is to follow links. Every summary representation includes a link to its detailed representation. ### Expanding responses Sometimes the detailed representation of a resource does not include all of the attributes of the resource by default. If this is the case, the request method will clearly document this and describe which attributes you can include in an expanded response. To include the additional attributes, append the `expand` request parameter to your request and add a comma-separated list of the attributes to include. For example, when you append `?expand=members,maintainers` to the [Get team](https://launchdarkly.com/docs/api/teams/get-team) endpoint, the expanded response includes both of these attributes. ### Links and addressability The best way to navigate the API is by following links. These are attributes in representations that link to other resources. The API always uses the same format for links: - Links to other resources within the API are encapsulated in a `_links` object - If the resource has a corresponding link to HTML content on the site, it is stored in a special `_site` link Each link has two attributes: - An `href`, which contains the URL - A `type`, which describes the content type For example, a feature resource might return the following: ```json { "_links": { "parent": { "href": "/api/features", "type": "application/json" }, "self": { "href": "/api/features/sort.order", "type": "application/json" } }, "_site": { "href": "/features/sort.order", "type": "text/html" } } ``` From this, you can navigate to the parent collection of features by following the `parent` link, or navigate to the site page for the feature by following the `_site` link. Collections are always represented as a JSON object with an `items` attribute containing an array of representations. Like all other representations, collections have `_links` defined at the top level. Paginated collections include `first`, `last`, `next`, and `prev` links containing a URL with the respective set of elements in the collection. ## Updates Resources that accept partial updates use the `PATCH` verb. Most resources support the [JSON patch](https://launchdarkly.com/docs/api#updates-using-json-patch) format. Some resources also support the [JSON merge patch](https://launchdarkly.com/docs/api#updates-using-json-merge-patch) format, and some resources support the [semantic patch](https://launchdarkly.com/docs/api#updates-using-semantic-patch) format, which is a way to specify the modifications to perform as a set of executable instructions. Each resource supports optional [comments](https://launchdarkly.com/docs/api#updates-with-comments) that you can submit with updates. Comments appear in outgoing webhooks, the audit log, and other integrations. When a resource supports both JSON patch and semantic patch, we document both in the request method. However, the specific request body fields and descriptions included in our documentation only match one type of patch or the other. ### Updates using JSON patch [JSON patch](https://datatracker.ietf.org/doc/html/rfc6902) is a way to specify the modifications to perform on a resource. JSON patch uses paths and a limited set of operations to describe how to transform the current state of the resource into a new state. JSON patch documents are always arrays, where each element contains an operation, a path to the field to update, and the new value. For example, in this feature flag representation: ```json { "name": "New recommendations engine", "key": "engine.enable", "description": "This is the description", ... } ``` You can change the feature flag's description with the following patch document: ```json [{ "op": "replace", "path": "/description", "value": "This is the new description" }] ``` You can specify multiple modifications to perform in a single request. You can also test that certain preconditions are met before applying the patch: ```json [ { "op": "test", "path": "/version", "value": 10 }, { "op": "replace", "path": "/description", "value": "The new description" } ] ``` The above patch request tests whether the feature flag's `version` is `10`, and if so, changes the feature flag's description. Attributes that are not editable, such as a resource's `_links`, have names that start with an underscore. ### Updates using JSON merge patch [JSON merge patch](https://datatracker.ietf.org/doc/html/rfc7386) is another format for specifying the modifications to perform on a resource. JSON merge patch is less expressive than JSON patch. However, in many cases it is simpler to construct a merge patch document. For example, you can change a feature flag's description with the following merge patch document: ```json { "description": "New flag description" } ``` ### Updates using semantic patch Some resources support the semantic patch format. A semantic patch is a way to specify the modifications to perform on a resource as a set of executable instructions. Semantic patch allows you to be explicit about intent using precise, custom instructions. In many cases, you can define semantic patch instructions independently of the current state of the resource. This can be useful when defining a change that may be applied at a future date. To make a semantic patch request, you must append `domain-model=launchdarkly.semanticpatch` to your `Content-Type` header. Here's how: ``` Content-Type: application/json; domain-model=launchdarkly.semanticpatch ``` If you call a semantic patch resource without this header, you will receive a `400` response because your semantic patch will be interpreted as a JSON patch. The body of a semantic patch request takes the following properties: * `comment` (string): (Optional) A description of the update. * `environmentKey` (string): (Required for some resources only) The environment key. * `instructions` (array): (Required) A list of actions the update should perform. Each action in the list must be an object with a `kind` property that indicates the instruction. If the instruction requires parameters, you must include those parameters as additional fields in the object. The documentation for each resource that supports semantic patch includes the available instructions and any additional parameters. For example: ```json { "comment": "optional comment", "instructions": [ {"kind": "turnFlagOn"} ] } ``` Semantic patches are not applied partially; either all of the instructions are applied or none of them are. If **any** instruction is invalid, the endpoint returns an error and will not change the resource. If all instructions are valid, the request succeeds and the resources are updated if necessary, or left unchanged if they are already in the state you request. ### Updates with comments You can submit optional comments with `PATCH` changes. To submit a comment along with a JSON patch document, use the following format: ```json { "comment": "This is a comment string", "patch": [{ "op": "replace", "path": "/description", "value": "The new description" }] } ``` To submit a comment along with a JSON merge patch document, use the following format: ```json { "comment": "This is a comment string", "merge": { "description": "New flag description" } } ``` To submit a comment along with a semantic patch, use the following format: ```json { "comment": "This is a comment string", "instructions": [ {"kind": "turnFlagOn"} ] } ``` ## Errors The API always returns errors in a common format. Here's an example: ```json { "code": "invalid_request", "message": "A feature with that key already exists", "id": "30ce6058-87da-11e4-b116-123b93f75cba" } ``` The `code` indicates the general class of error. The `message` is a human-readable explanation of what went wrong. The `id` is a unique identifier. Use it when you're working with LaunchDarkly Support to debug a problem with a specific API call. ### HTTP status error response codes | Code | Definition | Description | Possible Solution | | ---- | ----------------- | ------------------------------------------------------------------------------------------- | ---------------------------------------------------------------- | | 400 | Invalid request | The request cannot be understood. | Ensure JSON syntax in request body is correct. | | 401 | Invalid access token | Requestor is unauthorized or does not have permission for this API call. | Ensure your API access token is valid and has the appropriate permissions. | | 403 | Forbidden | Requestor does not have access to this resource. | Ensure that the account member or access token has proper permissions set. | | 404 | Invalid resource identifier | The requested resource is not valid. | Ensure that the resource is correctly identified by ID or key. | | 405 | Method not allowed | The request method is not allowed on this resource. | Ensure that the HTTP verb is correct. | | 409 | Conflict | The API request can not be completed because it conflicts with a concurrent API request. | Retry your request. | | 422 | Unprocessable entity | The API request can not be completed because the update description can not be understood. | Ensure that the request body is correct for the type of patch you are using, either JSON patch or semantic patch. | 429 | Too many requests | Read [Rate limiting](https://launchdarkly.com/docs/api#rate-limiting). | Wait and try again later. | ## CORS The LaunchDarkly API supports Cross Origin Resource Sharing (CORS) for AJAX requests from any origin. If an `Origin` header is given in a request, it will be echoed as an explicitly allowed origin. Otherwise the request returns a wildcard, `Access-Control-Allow-Origin: *`. For more information on CORS, read the [CORS W3C Recommendation](http://www.w3.org/TR/cors). Example CORS headers might look like: ```http Access-Control-Allow-Headers: Accept, Content-Type, Content-Length, Accept-Encoding, Authorization Access-Control-Allow-Methods: OPTIONS, GET, DELETE, PATCH Access-Control-Allow-Origin: * Access-Control-Max-Age: 300 ``` You can make authenticated CORS calls just as you would make same-origin calls, using either [token or session-based authentication](https://launchdarkly.com/docs/api#authentication). If you are using session authentication, you should set the `withCredentials` property for your `xhr` request to `true`. You should never expose your access tokens to untrusted entities. ## Rate limiting We use several rate limiting strategies to ensure the availability of our APIs. Rate-limited calls to our APIs return a `429` status code. Calls to our APIs include headers indicating the current rate limit status. The specific headers returned depend on the API route being called. The limits differ based on the route, authentication mechanism, and other factors. Routes that are not rate limited may not contain any of the headers described below. > ### Rate limiting and SDKs > > LaunchDarkly SDKs are never rate limited and do not use the API endpoints defined here. LaunchDarkly uses a different set of approaches, including streaming/server-sent events and a global CDN, to ensure availability to the routes used by LaunchDarkly SDKs. ### Global rate limits Authenticated requests are subject to a global limit. This is the maximum number of calls that your account can make to the API per ten seconds. All service and personal access tokens on the account share this limit, so exceeding the limit with one access token will impact other tokens. Calls that are subject to global rate limits may return the headers below: | Header name | Description | | ------------------------------ | -------------------------------------------------------------------------------- | | `X-Ratelimit-Global-Remaining` | The maximum number of requests the account is permitted to make per ten seconds. | | `X-Ratelimit-Reset` | The time at which the current rate limit window resets in epoch milliseconds. | We do not publicly document the specific number of calls that can be made globally. This limit may change, and we encourage clients to program against the specification, relying on the two headers defined above, rather than hardcoding to the current limit. ### Route-level rate limits Some authenticated routes have custom rate limits. These also reset every ten seconds. Any service or personal access tokens hitting the same route share this limit, so exceeding the limit with one access token may impact other tokens. Calls that are subject to route-level rate limits return the headers below: | Header name | Description | | ----------------------------- | ----------------------------------------------------------------------------------------------------- | | `X-Ratelimit-Route-Remaining` | The maximum number of requests to the current route the account is permitted to make per ten seconds. | | `X-Ratelimit-Reset` | The time at which the current rate limit window resets in epoch milliseconds. | A _route_ represents a specific URL pattern and verb. For example, the [Delete environment](https://launchdarkly.com/docs/api/environments/delete-environment) endpoint is considered a single route, and each call to delete an environment counts against your route-level rate limit for that route. We do not publicly document the specific number of calls that an account can make to each endpoint per ten seconds. These limits may change, and we encourage clients to program against the specification, relying on the two headers defined above, rather than hardcoding to the current limits. ### IP-based rate limiting We also employ IP-based rate limiting on some API routes. If you hit an IP-based rate limit, your API response will include a `Retry-After` header indicating how long to wait before re-trying the call. Clients must wait at least `Retry-After` seconds before making additional calls to our API, and should employ jitter and backoff strategies to avoid triggering rate limits again. ## OpenAPI (Swagger) and client libraries We have a [complete OpenAPI (Swagger) specification](https://app.launchdarkly.com/api/v2/openapi.json) for our API. We auto-generate multiple client libraries based on our OpenAPI specification. To learn more, visit the [collection of client libraries on GitHub](https://github.com/search?q=topic%3Alaunchdarkly-api+org%3Alaunchdarkly&type=Repositories). Alternatively, you can use the specification to generate client libraries to interact with our REST API in your language of choice. Or, you can refer to our API endpoints' documentation for guidance on how to make requests with a common HTTP library in your language of choice. Our OpenAPI specification is supported by several API-based tools such as Postman and Insomnia. In many cases, you can directly import our specification to explore our APIs. ## Method overriding Some firewalls and HTTP clients restrict the use of verbs other than `GET` and `POST`. In those environments, our API endpoints that use `DELETE`, `PATCH`, and `PUT` verbs are inaccessible. To avoid this issue, our API supports the `X-HTTP-Method-Override` header, allowing clients to "tunnel" `DELETE`, `PATCH`, and `PUT` requests using a `POST` request. For example, to call a `PATCH` endpoint using a `POST` request, you can include `X-HTTP-Method-Override:PATCH` as a header. ## Beta resources We sometimes release new API resources in **beta** status before we release them with general availability. Resources that are in beta are still undergoing testing and development. They may change without notice, including becoming backwards incompatible. We try to promote resources into general availability as quickly as possible. This happens after sufficient testing and when we're satisfied that we no longer need to make backwards-incompatible changes. We mark beta resources with a "Beta" callout in our documentation, pictured below: > ### This feature is in beta > > To use this feature, pass in a header including the `LD-API-Version` key with value set to `beta`. Use this header with each call. To learn more, read [Beta resources](https://launchdarkly.com/docs/api#beta-resources). > > Resources that are in beta are still undergoing testing and development. They may change without notice, including becoming backwards incompatible. ### Using beta resources To use a beta resource, you must include a header in the request. If you call a beta resource without this header, you receive a `403` response. Use this header: ``` LD-API-Version: beta ``` ## Federal and EU environments In addition to the commercial versions, LaunchDarkly offers instances for federal agencies and those based in the European Union (EU). ### Federal environments The version of LaunchDarkly that is available on domains controlled by the United States government is different from the version of LaunchDarkly available to the general public. If you are an employee or contractor for a United States federal agency and use LaunchDarkly in your work, you likely use the federal instance of LaunchDarkly. If you are working in the federal instance of LaunchDarkly, the base URI for each request is `https://app.launchdarkly.us`. To learn more, read [LaunchDarkly in federal environments](https://launchdarkly.com/docs/home/infrastructure/federal). ### EU environments The version of LaunchDarkly that is available in the EU is different from the version of LaunchDarkly available to other regions. If you are based in the EU, you likely use the EU instance of LaunchDarkly. The LaunchDarkly EU instance complies with EU data residency principles, including the protection and confidentiality of EU customer information. If you are working in the EU instance of LaunchDarkly, the base URI for each request is `https://app.eu.launchdarkly.com`. To learn more, read [LaunchDarkly in the European Union (EU)](https://launchdarkly.com/docs/home/infrastructure/eu). ## Versioning We try hard to keep our REST API backwards compatible, but we occasionally have to make backwards-incompatible changes in the process of shipping new features. These breaking changes can cause unexpected behavior if you don't prepare for them accordingly. Updates to our REST API include support for the latest features in LaunchDarkly. We also release a new version of our REST API every time we make a breaking change. We provide simultaneous support for multiple API versions so you can migrate from your current API version to a new version at your own pace. ### Setting the API version per request You can set the API version on a specific request by sending an `LD-API-Version` header, as shown in the example below: ``` LD-API-Version: 20240415 ``` The header value is the version number of the API version you would like to request. The number for each version corresponds to the date the version was released in `yyyymmdd` format. In the example above the version `20240415` corresponds to April 15, 2024. ### Setting the API version per access token When you create an access token, you must specify a specific version of the API to use. This ensures that integrations using this token cannot be broken by version changes. Tokens created before versioning was released have their version set to `20160426`, which is the version of the API that existed before the current versioning scheme, so that they continue working the same way they did before versioning. If you would like to upgrade your integration to use a new API version, you can explicitly set the header described above. > ### Best practice: Set the header for every client or integration > > We recommend that you set the API version header explicitly in any client or integration you build. > > Only rely on the access token API version during manual testing. ### API version changelog <table> <tr> <th>Version</th> <th>Changes</th> <th>End of life (EOL)</th> </tr> <tr> <td>`20240415`</td> <td> <ul><li>Changed several endpoints from unpaginated to paginated.

Ame Ame provides a simple command-line interface API for Ruby¹. It can be used to provide both simple interfaces like that of ‹rm›² and complex ones like that of ‹git›³. It uses Ruby’s own classes, methods, and argument lists to provide an interface that is both simple to use from the command-line side and from the Ruby side. The provided command-line interface is flexible and follows commond standards for command-line processing. ¹ See http://ruby-lang.org/ ² See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/rm.html ³ See http://git-scm.com/docs/ § Usage Let’s begin by looking at two examples, one where we mimic the POSIX¹ command-line interface to the ‹rm› command. Looking at the entry² in the standard, ‹rm› takes the following options: = -f. = Do not prompt for confirmation. = -i. = Prompt for confirmation. = -R. = Remove file hierarchies. = -r. = Equivalent to /-r/. It also takes the following arguments: = FILE. = A pathname or directory entry to be removed. And actually allows one or more of these /FILE/ arguments to be given. We also note that the ‹rm› command is described as a command to “remove directory entries”. ¹ See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/contents.html ² See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/rm.html Let’s turn this specification into one using Ame’s API. We begin by adding a flag for each of the options listed above: class Rm &lt; Ame::Root flag 'f', '', false, 'Do not prompt for confirmation' flag 'i', '', nil, 'Prompt for confirmation' do |options| options['f'] = false end flag 'R', '', false, 'Remove file hierarchies' flag 'r', '', nil, 'Equivalent to -R' do |options| options['r'] = true end A flag¹ is a boolean option that doesn’t take an argument. Each flag gets a short and long name, where an empty name means that there’s no corresponding short or long name for the flag, a default value (true, false, or nil), and a description of what the flag does. Each flag can also optionally take a block that can do further processing. In this case we use this block to modify the Hash that maps option names to their values passed to the block to set other flags’ values than the ones that the block is associated with. As these flags (‘i’ and ‘r’) aren’t themselves of interest, their default values have been set to nil, which means that they won’t be included in the Hash that maps option names to their values when passed to the method. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#flag-class-method There are quite a few other kinds of options besides flags that can be defined using Ame, but flags are all that are required for this example. We’ll get to the other kinds in later examples. Next we add a “splus” argument. splus 'FILE', String, 'File to remove' A splus¹ argument is like a Ruby “splat”, that is, an Array argument at the end of the argument list to a method preceded by a star, except that a splus requires at least one argument. A splus argument gets a name for the argument (‹FILE›), the type of argument it represents (String), and a description. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#splus-class-method Then we add a description of the command (method) itself: description 'Remove directory entries' Descriptions¹ will be used in help output to assist the user in using the command. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#description-class-method Finally, we add the Ruby method that’ll implement the command (all preceding code included here for completeness): class Rm &lt; Ame::Root version '1.0.0' flag 'f', '', false, 'Do not prompt for confirmation' flag 'i', '', nil, 'Prompt for confirmation' do |options| options['f'] = false end flag 'R', '', false, 'Remove file hierarchies' flag 'r', '', nil, 'Equivalent to -R' do |options| options['r'] = true end splus 'FILE', String, 'File to remove' description 'Remove directory entries' def rm(files, options = {}) require 'fileutils' FileUtils.send options['R'] ? :rm_r : :rm, [first] + rest, :force =&gt; options['f'] end end Actually, another bit of code was also added, namely version '1.0.0' This sets the version¹ String of the command. This information is used when the command is invoked with the “‹--version›” flag. This flag is automatically added, so you don’t need to add it yourself. Another flag, “‹--help›”, is also added automatically. When given, this flag’ll make Ame output usage information of the command. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#version-class-method To actually run the command, all you need to do is invoke Rm.process This’ll invoke the command using the command-line arguments stored in ‹ARGV›, but you can also specify other ones if you want to: Rm.process 'rm', %w[-r /tmp/*] The first argument to #process¹ is the name of the method to invoke, which defaults to ‹File.basename($0)›, and the second argument is an Array of Strings that should be processed as command-line arguments passed to the command. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#process-class-method If you’d store the complete ‹Rm› class defined above in a file called ‹rm› and add ‹#! /usr/bin/ruby -w› at the beginning and ‹Rm.process› at the end, you’d have a fully functional ‹rm› command (after making it executable). Let’s see it in action: % rm --help Usage: rm [OPTIONS]... FILE... Remove directory entries Arguments: FILE... File to remove Options: -R Remove file hierarchies -f Do not prompt for confirmation --help Display help for this method -i Prompt for confirmation -r Equivalent to -R --version Display version information % rm --version rm 1.0.0 Some commands are more complex than ‹rm›. For example, ‹git›¹ has a rather complex command-line interface. We won’t mimic it all here, but let’s introduce the rest of the Ame API using a fake ‹git› clone as an example. ¹ See http://git-scm.com/docs/ ‹Git› uses sub-commands to achieve most things. Implementing sub-commands with Ame is done using a “dispatch”. We’ll discuss dispatches in more detail later, but suffice it to say that a dispatch delegates processing to a child class that’ll handle the sub-command in question. We begin by defining our main ‹git› command using a class called ‹Git› under the ‹Git::CLI› namespace: module Git end class Git::CLI &lt; Ame::Root version '1.0.0' class Git &lt; Ame::Class description 'The stupid content tracker' def initialize; end We’re setting things up to use the ‹Git› class as a dispatch in the ‹Git::CLI› class. The description on the ‹initialize› method will be used as a description of the ‹git› dispatch command itself. Next, let’s add the ‹format-patch›¹ sub-command: description 'Prepare patches for e-mail submission' flag ?n, 'numbered', false, 'Name output in [PATCH n/m] format' flag ?N, 'no-numbered', nil, 'Name output in [PATCH] format' do |options| options['numbered'] = false end toggle ?s, 'signoff', false, 'Add Signed-off-by: line to the commit message' switch '', 'thread', 'STYLE', nil, Ame::Types::Enumeration[:shallow, :deep], 'Controls addition of In-Reply-To and References headers' flag '', 'no-thread', nil, 'Disables addition of In-Reply-To and Reference headers' do |options, _| options.delete 'thread' end option '', 'start-number', 'N', 1, 'Start numbering the patches at N instead of 1' multioption '', 'to', 'ADDRESS', String, 'Add a To: header to the email headers' optional 'SINCE', 'N/A', 'Generate patches for commits after SINCE' def format_patch(since = '', options = {}) p since, options end ¹ See http://git-scm.com/docs/git-format-patch/ We’re using quite a few new Ame commands here. Let’s look at each in turn: toggle ?s, 'signoff', false, 'Add Signed-off-by: line to the commit message' A “toggle”¹ is a flag that also has an inverse. Beyond the flags ‘s’ and “signoff”, the toggle also defines “no-signoff”, which will set “signoff” to false. This is useful if you want to support configuration files that set “signoff”’s default to true, but still allow it to be overridden on the command line. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#toggle-class-method When using the short form of a toggle (and flag and switch), multiple ones may be juxtaposed after the initial one. For example, “‹-sn›” is equivalent to “‹-s -n›” to “git format-patch›”. switch '', 'thread', 'STYLE', nil, Ame::Types::Enumeration[:shallow, :deep], 'Controls addition of In-Reply-To and References headers' A “switch”¹ is an option that takes an optional argument. This allows you to have separate defaults for when the switch isn’t present on the command line and for when it’s given without an argument. The third argument to a switch is the name of the argument. We’re also introducing a new concept here in ‹Ame::Types::Enumeration›. An enumeration² allows you to limit the allowed input to a set of Symbols. An enumeration also has a default value in the first item to its constructor (which is aliased as ‹.[]›). In this case, the “thread” switch defaults to nil, but, when given, will default to ‹:shallow› if no argument is given. If an argument is given it must be either “shallow” or “deep”. A switch isn’t required to take an enumeration as its argument default and can take any kind of default value for its argument that Ame knows how to handle. We’ll look at this in more detail later, but know that the type of the default value will be used to inform Ame how to parse a command-line argument into a Ruby value. An argument to a switch must be given, in this case, as “‹--thread=deep›” on the command line. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#switch-class-method ² See http://disu.se/software/ame-1.0/api/user/Ame/Types/Enumeration/ option '', 'start-number', 'N', 1, 'Start numbering the patches at N instead of 1' An “option”¹ is an option that takes an argument. The argument must always be present and may be given, in this case, as “‹--start-number=2›” or “‹--start-number 2›” on the command line. For a short-form option, anything that follows the option is seen as an argument, so assuming that “start-number” also had a short name of ‘S’, “‹-S2›” would be equivalent to “‹-S 2›”, which would be equivalent to “‹--start-number 2›”. Note that “‹-snS2›” would still work as expected. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#option-class-method multioption '', 'to', 'ADDRESS', String, 'Add a To: header to the email headers' A “multioption”¹ is an option that takes an argument and may be repeated any number of times. Each argument will be added to an Array stored in the Hash that maps option names to their values. Instead of taking a default argument, it takes a type for the argument (String, in this case). Again, types are used to inform Ame how to parse command-line arguments into Ruby values. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#multioption-class-method optional 'SINCE', 'N/A', 'Generate patches for commits after SINCE' An “optional”¹ argument is an argument that isn’t required. If it’s not present on the command line it’ll get its default value (the String ‹'N/A'›, in this case). ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#optional-class-method We’ve now covered all kinds of options and one new kind of argument. There are three more types of argument (one that we’ve already seen and two new) that we’ll look into now: “argument”, “splat”, and “splus”. description 'Annotate file lines with commit information' argument 'FILE', String, 'File to annotate' def annotate(file) p file end An “argument”¹ is an argument that’s required. If it’s not present on the command line, an error will be raised (and by default reported to the terminal). As it’s required, it doesn’t take a default, but rather a type. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#argument-class-method description 'Add file contents to the index' splat 'PATHSPEC', String, 'Files to add content from' def add(paths) p paths end A “splat”¹ is an argument that’s not required, but may be given any number of times. The type of a splat is the type of one argument and the type of a splat as a whole is an Array of values of that type. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#splat-class-method description 'Display gitattributes information' splus 'PATHNAME', String, 'Files to list attributes of' def check_attr(paths) p paths end A “splus”¹ is an argument that’s required, but may also be given any number of times. The type of a splus is the type of one argument and the type of a splus as a whole is an Array of values of that type. ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#splus-class-method Now that we’ve seen all kinds of options and arguments, let’s look on an additional tool at our disposal, the dispatch¹. class Remote &lt; Ame::Class description 'Manage set of remote repositories' def initialize; end description 'Shows a list of existing remotes' flag 'v', 'verbose', false, 'Show remote URL after name' def list(options = {}) p options end description 'Adds a remote named NAME for the repository at URL' argument 'name', String, 'Name of the remote to add' argument 'url', String, 'URL to the repository of the remote to add' def add(name, url) p name, url end end ¹ See http://disu.se/software/ame-1.0/api/user/Ame/Class#dispatch-class-method Here we’re defining a child class to Git::CLI::Git called “Remote” that doesn’t introduce anything new. Then we set up the dispatch: dispatch Remote, :default =&gt; 'list' This adds a method called “remote” to Git::CLI::Git that will dispatch processing of the command line to an instance of the Remote class when “‹git remote›” is seen on the command line. The “remote” method expects an argument that’ll be used to decide what sub-command to execute. Here we’ve specified that in the absence of such an argument, the “list” method should be invoked. We add the same kind of dispatch to Git under Git::CLI: dispatch Git and then we’re done. Here’s all the previous code in its entirety: module Git end class Git::CLI &lt; Ame::Root version '1.0.0' class Git &lt; Ame::Class description 'The stupid content tracker' def initialize; end description 'Prepare patches for e-mail submission' flag ?n, 'numbered', false, 'Name output in [PATCH n/m] format' flag ?N, 'no-numbered', nil, 'Name output in [PATCH] format' do |options| options['numbered'] = false end toggle ?s, 'signoff', false, 'Add Signed-off-by: line to the commit message' switch '', 'thread', 'STYLE', nil, Ame::Types::Enumeration[:shallow, :deep], 'Controls addition of In-Reply-To and References headers' flag '', 'no-thread', nil, 'Disables addition of In-Reply-To and Reference headers' do |options, _| options.delete 'thread' end option '', 'start-number', 'N', 1, 'Start numbering the patches at N instead of 1' multioption '', 'to', 'ADDRESS', String, 'Add a To: header to the email headers' optional 'SINCE', 'N/A', 'Generate patches for commits after SINCE' def format_patch(since = '', options = {}) p since, options end description 'Annotate file lines with commit information' argument 'FILE', String, 'File to annotate' def annotate(file) p file end description 'Add file contents to the index' splat 'PATHSPEC', String, 'Files to add content from' def add(paths) p paths end description 'Display gitattributes information' splus 'PATHNAME', String, 'Files to list attributes of' def check_attr(paths) p paths end class Remote &lt; Ame::Class description 'Manage set of remote repositories' def initialize; end description 'Shows a list of existing remotes' flag 'v', 'verbose', false, 'Show remote URL after name' def list(options = {}) p options end description 'Adds a remote named NAME for the repository at URL' argument 'name', String, 'Name of the remote to add' argument 'url', String, 'URL to the repository of the remote to add' def add(name, url) p name, url end end dispatch Remote, :default =&gt; 'list' end dispatch Git end If we put this code in a file called “git” and add ‹#! /usr/bin/ruby -w› at the beginning and ‹Git::CLI.process› at the end, you’ll have a very incomplete git command-line interface on your hands. Let’s look at what some of its ‹--help› output looks like: % git --help Usage: git [OPTIONS]... METHOD [ARGUMENTS]... The stupid content tracker Arguments: METHOD Method to run [ARGUMENTS]... Arguments to pass to METHOD Options: --help Display help for this method --version Display version information Methods: add Add file contents to the index annotate Annotate file lines with commit information check-attr Display gitattributes information format-patch Prepare patches for e-mail submission remote Manage set of remote repositories % git format-patch --help Usage: git format-patch [OPTIONS]...

Contentful API wrapper library exposing an ActiveRecord-like interface

The Tripletex API is a **RESTful API**, which does not implement PATCH, but uses a PUT with optional fields. **Actions** or commands are represented in our RESTful path with a prefixed `:`. Example: `/v2/hours/123/:approve`. **Summaries** or aggregated results are represented in our RESTful path with a prefixed <code>&gt;</code>. Example: <code>/v2/hours/&gt;thisWeeksBillables</code>. **"requestID"** is a key found in all validation and error responses. If additional log information is absolutely necessary, our support division can locate the key value. **Download** the [swagger.json](/v2/swagger.json) file [OpenAPI Specification](https://github.com/OAI/OpenAPI-Specification) to [generate code](https://github.com/swagger-api/swagger-codegen). This document was generated from the Swagger JSON file. **version:** This is a versioning number found on all DB records. If included, it will prevent your PUT/POST from overriding any updates to the record since your GET. **Date & DateTime** follows the **ISO 8601** standard. Date: `YYYY-MM-DD`. DateTime: `YYYY-MM-DDThh:mm:ssZ` **Sorting** is done by specifying a comma separated list, where a `-` prefix denotes descending. You can sort by sub object with the following format: `project.name, -date`. **Searching:** is done by entering values in the optional fields for each API call. The values fall into the following categories: range, in, exact and like. **Missing fields or even no response data** can occur because result objects and fields are filtered on authorization. **See [FAQ](https://tripletex.no/execute/docViewer?articleId=906&language=0) for more additional information.** ## Authentication: - **Tokens:** The Tripletex API uses 3 different tokens - **consumerToken**, **employeeToken** and **sessionToken**. - **consumerToken** is a token provided to the consumer by Tripletex after the API 2.0 registration is completed. - **employeeToken** is a token created by an administrator in your Tripletex account via the user settings and the tab "API access". Each employee token must be given a set of entitlements. [Read more here.](https://tripletex.no/execute/docViewer?articleId=853&language=0) - **sessionToken** is the token from `/token/session/:create` which requires a consumerToken and an employeeToken created with the same consumer token, but not an authentication header. See how to create a sessionToken [here](https://tripletex.no/execute/docViewer?articleId=855&language=0). - The session token is used as the password in "Basic Authentication Header" for API calls. - Use blank or `0` as username for accessing the account with regular employee token, or if a company owned employee token accesses <code>/company/&gt;withLoginAccess</code> or <code>/token/session/&gt;whoAmI</code>. - For company owned employee tokens (accounting offices) the ID from <code>/company/&gt;withLoginAccess</code> can be used as username for accessing client accounts. - If you need to create the header yourself use <code>Authorization: Basic &lt;base64encode('0:sessionToken')&gt;</code>. ## Tags: - <div class="tag-icon-beta"></div> **[BETA]** This is a beta endpoint and can be subject to change. - <div class="tag-icon-deprecated"></div> **[DEPRECATED]** Deprecated means that we intend to remove/change this feature or capability in a future "major" API release. We therefore discourage all use of this feature/capability. ## Fields: Use the `fields` parameter to specify which fields should be returned. This also supports fields from sub elements. Example values: - `project,activity,hours` returns `{project:..., activity:...., hours:...}`. - just `project` returns `"project" : { "id": 12345, "url": "tripletex.no/v2/projects/12345" }`. - `project(*)` returns `"project" : { "id": 12345 "name":"ProjectName" "number.....startDate": "2013-01-07" }`. - `project(name)` returns `"project" : { "name":"ProjectName" }`. - All elements and some subElements : `*,activity(name),employee(*)`. ## Changes: To get the changes for a resource, `changes` have to be explicitly specified as part of the `fields` parameter, e.g. `*,changes`. There are currently two types of change available: - `CREATE` for when the resource was created - `UPDATE` for when the resource was updated NOTE: For objects created prior to October 24th 2018 the list may be incomplete, but will always contain the CREATE and the last change (if the object has been changed after creation). ## Rate limiting in each response header: Rate limiting is performed on the API calls for an employee for each API consumer. Status regarding the rate limit is returned as headers: - `X-Rate-Limit-Limit` - The number of allowed requests in the current period. - `X-Rate-Limit-Remaining` - The number of remaining requests. - `X-Rate-Limit-Reset` - The number of seconds left in the current period. Once the rate limit is hit, all requests will return HTTP status code `429` for the remainder of the current period. ## Response envelope: ``` { "fullResultSize": ###, "from": ###, // Paging starting from "count": ###, // Paging count "versionDigest": "Hash of full result", "values": [...list of objects...] } { "value": {...single object...} } ``` ## WebHook envelope: ``` { "subscriptionId": ###, "event": "object.verb", // As listed from /v2/event/ "id": ###, // Object id "value": {... single object, null if object.deleted ...} } ``` ## Error/warning envelope: ``` { "status": ###, // HTTP status code "code": #####, // internal status code of event "message": "Basic feedback message in your language", "link": "Link to doc", "developerMessage": "More technical message", "validationMessages": [ // Will be null if Error { "field": "Name of field", "message": "Validation failure information" } ], "requestId": "UUID used in any logs" } ``` ## Status codes / Error codes: - **200 OK** - **201 Created** - From POSTs that create something new. - **204 No Content** - When there is no answer, ex: "/:anAction" or DELETE. - **400 Bad request** - - **4000** Bad Request Exception - **11000** Illegal Filter Exception - **12000** Path Param Exception - **24000** Cryptography Exception - **401 Unauthorized** - When authentication is required and has failed or has not yet been provided - **3000** Authentication Exception - **9000** Security Exception - **403 Forbidden** - When AuthorisationManager says no. - **404 Not Found** - For content/IDs that does not exist. - **6000** Not Found Exception - **409 Conflict** - Such as an edit conflict between multiple simultaneous updates - **7000** Object Exists Exception - **8000** Revision Exception - **10000** Locked Exception - **14000** Duplicate entry - **422 Bad Request** - For Required fields or things like malformed payload. - **15000** Value Validation Exception - **16000** Mapping Exception - **17000** Sorting Exception - **18000** Validation Exception - **21000** Param Exception - **22000** Invalid JSON Exception - **23000** Result Set Too Large Exception - **429 Too Many Requests** - Request rate limit hit - **500 Internal Error** - Unexpected condition was encountered and no more specific message is suitable - **1000** Exception
