404 Not found
405 Method not allowed
409 Conflict
429 Too many requests
500 An unexpected internal error occurred even though the request was valid
503 Service unavailable

Authentication

With the authentication API you can create tokens for OAuth authentication. The API supports OAuth 2.0.

Create access token

Use POST /oauth/token to create a bearer access token enabling an OAuth client to authenticate itself in the Usage Engine REST API. You have to create an Application Access in Usage Engine to retrieve the client ID and client secret, see Application Access for detailed instructions.

Request Body schema: application/json

Credentials used for authenticating the client to the authorization server.

audience
required
string

The intended recipients which should accept and process the token. Use the base URL for the environment you are accessing.

client_id
required
string

The client ID generated when creating the Application Access in Usage Engine CE.

client_secret
required
string

The client secret generated when creating the Application Access in Usage Engine CE.

grant_type
required
