User Profile

I could get "access_token" and "refresh_token" from following URL:POST https://appleid.apple.com/auth/tokenBut I don't know the API of getting User Information using "access_token"Is there any API that accept the "access_token" as the input and return the User Information (user ID, email...)?It is very good that there is an API like this: https://stackoverflow.com/questions/7130648/get-user-info-via-google-apiThank you very much.
