On my client mobile app I perform apple-id authorization and obtain IdentityToken from Apple server.

Now I want to send this IdentityToken (looks like string xJahN102mdPq2jHAiisPsla012nYahKL ) to my application server. And I want to get user's email on my application server via processing this token.

For google (for example) it is plain simple way, I just make a GET request to:

https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=google_identity_token

And in case the token is correct, Google returns JSON with the user's email inside.

What apple server endpoint should I call and what HTTP request should be done (GET, POST, etc) to obtain user's email using IdentityToken ?

Thank you.

As far as I understand the situation it is not possible. Instead of that I have to pass Identity token along with other credentials, including email, to my application server and perform 2 steps.

Check passed data on integrity
Call to Apple servers for refresh token
