Abstract

This specification extends the OAuth 2.0 Token Introspection method defined in RFC7662. It defines a method for an OAuth 2.0 Authorization Server (AS) that receives an introspection request for a token it did not issue, to query a different, trusted AS. This enables the AS to determine the active state of the token and to retrieve associated metadata.
