OIDC Authorization Endpoint
From the OIDC Specification:
3.1.1. Authorization Code Flow Steps
The Authorization Code Flow goes through the following steps.
- Client prepares an Authentication Request containing the desired request
parameters.
- Client sends the request to the Authorization Server.
- Authorization Server Authenticates the End-User.
- Authorization Server obtains End-User Consent/Authorization.
- Authorization Server sends the End-User back to the Client with an
Authorization Code.
- Client requests a response using the Authorization Code at the Token
Endpoint.
- Client receives a response that contains an ID Token and Access Token in
the response body.
- Client validates the ID token and retrieves the End-User's Subject
Identifier.
