{{< api-method method="get" host="https://mastodon.example" path="/oauth/authorize" title="Authorize a user" >}} {{< api-method-description >}}

Displays an authorization form to the user. If approved, it will create and return an authorization code, then redirect to the desired redirect_uri, or show the authorization code if urn:ietf:wg:oauth:2.0:oob was requested. The authorization code can be used while requesting a token to obtain access to user-level methods.

{{< endapi-method-description >}} {{< api-method-spec >}} {{< api-method-request >}} {{< api-method-form-data-parameters >}} {{< api-method-parameter name="response_type" type="string" required=true >}} Should be set equal to code. {{< endapi-method-parameter >}} {{< api-method-parameter name="client_id" type="string" required=true >}} Client ID, obtained during app registration. {{< endapi-method-parameter >}} {{< api-method-parameter name="redirect_uri" type="string" required=true >}} Set a URI to redirect the user to. If this parameter is set to urn:ietf:wg:oauth:2.0:oob then the authorization code will be shown instead. Must match one of the redirect URIs declared during app registration. {{< endapi-method-parameter >}} {{< api-method-parameter name="scope" type="string" required=false >}} List of requested OAuth scopes, separated by spaces or by pluses, if using query parameters. Must be a subset of scopes declared during app registration. If not provided, defaults to read. {{< endapi-method-parameter >}} {{< api-method-parameter name="force_login" type="bool" required=false >}} Added in 2.6.0. Forces the user to re-login, which is necessary for authorizing with multiple accounts from the same instance. {{< endapi-method-parameter >}} {{< endapi-method-form-data-parameters >}} {{< endapi-method-request >}} {{< api-method-response >}} {{< api-method-response-example httpCode=200 >}} {{< api-method-response-example-description >}}

The authorization code will be returned as a query parameter named code. {{< endapi-method-response-example-description >}}

{{< endapi-method-response-example >}} {{< api-method-response-example httpCode=400 >}} {{< api-method-response-example-description >}}

If the authorization code is incorrect or has been used already, the request will fail. {{< endapi-method-response-example-description >}}

{
  "error": "invalid_grant",
  "error_description": "The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."

Returns an access token, to be used during API calls that are not public.

{{< endapi-method-description >}} {{< api-method-spec >}} {{< api-method-request >}} {{< api-method-form-data-parameters >}} {{< api-method-parameter name="grant_type" type="string" required=true >}} Set equal to authorization_code if code is provided in order to gain user-level access.

Store this access_token for later use with auth-required methods. The token should be passed as an HTTP Authorization header when making API calls, with the value Bearer access_token {{< endapi-method-response-example-description >}}

If you try to request a scope that was not included when registering the app, the request will fail. {{< endapi-method-response-example-description >}}

{
  "error": "invalid_scope",
  "error_description": "The requested scope is invalid, unknown, or malformed."
}

{{< endapi-method-response-example >}} {{< api-method-response-example httpCode=401 >}} {{< api-method-response-example-description >}}

If client_id and client_secret do not match or are invalid, the request will fail. {{< endapi-method-response-example-description >}}

{
  "error": "invalid_client",
  "error_description": "Client authentication failed due to unknown client, no client authentication included, or unsupported authentication method."

Revoke an access token to make it no longer valid for use.

{{< endapi-method-description >}} {{< api-method-spec >}} {{< api-method-request >}} {{< api-method-form-data-parameters >}} {{< api-method-parameter name="client_id" type="string" required=true >}} Client ID, obtained during app registration {{< endapi-method-parameter >}} {{< api-method-parameter name="client_secret" type="string" required=true >}} Client secret, obtained during app registration {{< endapi-method-parameter >}} {{< api-method-parameter name="token" type="string" required=true >}} The previously obtained token, to be invalidated {{< endapi-method-parameter >}} {{< endapi-method-form-data-parameters >}} {{< endapi-method-request >}} {{< api-method-response >}} {{< api-method-response-example httpCode=200 >}} {{< api-method-response-example-description >}}

If you own the provided token, the API call will provide an empty response. This operation is idempotent, so calling this API multiple times will still return OK. {{< endapi-method-response-example-description >}}

{}

{{< endapi-method-response-example >}} {{< api-method-response-example httpCode=403 >}} {{< api-method-response-example-description >}}

If you provide a token you do not own, or no token at all, the API call will return a 403 error. {{< endapi-method-response-example-description >}}

{
  "error": "unauthorized_client",
  "error_description": "You are not authorized to revoke this token"
