Overview#OAuth 2.0 Dynamic Client Registration Protocol is described within RFC 7591
In order for an OAuth 2.0 RFC 6749 client to utilize an OAuth 2.0 Authorization Server, the OAuth Client needs specific information to interact with the server, including an OAuth 2.0 Client_id to use at that Authorization Server.
Dynamic OAuth 2.0 Client Registration#The specification describes how an OAuth Client can be dynamically registered with an authorization server to obtain this information.
As part of the registration process, this specification also defines a mechanism for the client to present the Authorization Server with a set of metadata, such as a set of valid redirection URIs. This metadata can either be communicated in a self-asserted fashion or as a set of metadata called a software statement, which is digitally signed or MACed; in the case of a software statement, the issuer is vouching for the validity of the data about the client.
Traditionally, registration of a client with an Authorization Server is performed manually. The mechanisms defined in this specification can be used either for a client to dynamically register itself with authorization servers or for a client developer to programmatically register the client with Authorization Servers.
Multiple applications using OAuth 2.0 have previously developed mechanisms for accomplishing such registrations. This specification generalizes the registration mechanisms defined by the OpenID Connect Dynamic Client Registration 1.0 OpenID.Registration specification and used by the User Managed Access (UMA) Profile of OAuth 2.0 I-D.hardjono-oauth-umacore specification in a way that is compatible with both, while being applicable to a wider set of OAuth 2.0 use cases.
