Client Endpoint (Redirection URI | Redirection Endpoint | User Agent Redirection)

The client endpoint is an endpoint used by the authorization endpoint to return authorization responses containing authorization credentials to the client via the resource owner user-agent (typically a browser).

The client endpoint is also known as:

• the redirection endpoint
• the redirection URI
• The user-agent redirection

After completing its interaction with the resource owner, the authorization endpoint directs the resource owner's user-agent back to the client via a redirection endpoint.

The redirection endpoint URI:

• MUST be an absolute URI.
• MAY include an application/x-www-form-urlencoded formatted query component, which MUST be retained when adding additional query parameters.
• MUST NOT include a fragment component.

The client's redirection endpoint can be defined :

• during the client registration process
• or when making a authorization request.

during the client registration process

With the authorization request, you can defined the redirection uri using the redirect_uri request parameter.
