OAuth Protocol Flow - Client Credentials

This grant is suitable for machine-to-machine authentication where a specific user’s permission to access data is not required. It is used by clients to obtain an access token outside of the context of a user to access resources about themselves rather than to access a user’s resources.

Endpoint	Parameters	Response
/oauth2.0/accessToken	grant_type=client_credentials&client_id=client&client_secret=secret	The access token.

Because there is no redirect_uri specified by this grant type, the service identifier recognized by CAS and matched in the service registry is taken as the client_id instead. You may optionally also pass along a service or X-service header value that identifies the target application url. The header value must match the OAuth service definition in the registry that is linked to the client id.
