-This is the callback endpoint from the OIDC Provider:

-It will exchange a grant for the following tokens:
-
-* access_token
-* id_token
-* refresh_token
-
-# These tokens are encoded as a Base64 JSON string and stored in a session cookie

-For Example:

-The following is an example of the base64 value stored in the session cookie:
