Access Token Authentication

The client MUST authenticate with the authorization server. Confidential clients or other clients issued client credentials MUST authenticate with the authorization server when making requests to the token endpoint.

POST /token HTTP/1.1
Host: server.example.com
Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
