LaunchDarkly Context settings API

You can use the context settings API to assign a context to a specific variation for any feature flag. To learn more, read [View and manage contexts](https://launchdarkly.com/docs/home/observability/context-attributes#view-and-manage-contexts).

OpenAPI Specification

openapi: 3.2.0
info:
  title: LaunchDarkly REST Context settings API
  description: 'This documentation describes LaunchDarkly''s REST API. To access the complete OpenAPI spec directly, use Get OpenAPI spec. To learn how to use LaunchDarkly using the user interface (UI) instead, read our product documentation. ## 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, or session cookies. Other authentication mechanisms are not supported. You can manage personal access tokens on your **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 | 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** 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** 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, 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, Cross-Origin Resource Sharing (CORS) extensions used during development can modify the Origin header and cause 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.'

      summary: Update flag settings for context
      description: 'Enable or disable a feature flag for a context based on its context kind and key.


        In the request body, the `setting` should be the variation value to set for the context. It must match the flag''s variation type. For example, for a boolean flag you can use `"setting": true` or `"setting": false` in the request body. For a string flag, you can use `"setting": "existing_variation_value_to_use"`.


        Omitting the `setting` attribute from the request body, or including a `setting` of `null`, erases the current setting for a context.


        If you previously patched the flag, and the patch included the context''s data, LaunchDarkly continues to use that data. If LaunchDarkly has never encountered the combination of the context''s key and kind before, it calculates the flag values based on the context kind and key.'
