YiweiM.44026 (Customer) asked a question.
I am in a situation that I would like to refresh a user id token silently.
As the /authorize endpoint will require a redriection, I decided to use /token endpoint with refresh token
My question is, is that possible for me to retrieve id token alone from /token endpoint and make it a fat id token or I have to use /authorize endpoint to get a fat id token

Hello @YiweiM.44026 (Customer) Thank you for reaching out to our Community!
At this time you can't get a fat token with Org as, you only get a thin token. The only way to get a fat token is to only request an ID token via Implicit flow (covered in the below doc):

Please note: "This behavior is based on the OpenID specifications about scope-dependent claims. See the following quote from section 5.4:
The Claims requested by the profile, email, address, and phone scope values are returned from the UserInfo Endpoint, as described in Section 5.3.2, when a response_type value is used that results in an Access Token being issued. However, when no Access Token is issued (which is the case for the response_type value id_token), the resulting Claims are returned in the ID Token."
Hope this helps!
