             OAuth 2.0 Dynamic Client Registration Protocol

Abstract

   This specification defines mechanisms for dynamically registering
   OAuth 2.0 clients with authorization servers.  Registration requests
   send a set of desired client metadata values to the authorization
   server.  The resulting registration responses return a client
   identifier to use at the authorization server and the client metadata
   values registered for the client.  The client can then use this
   registration information to communicate with the authorization server
   using the OAuth 2.0 protocol.  This specification also defines a set
   of common client metadata fields and values for clients to use during
   registration.
