expo-apple-authentication for integrating with Apple Auth.
I’ve set everything up in Apple Dev console. I can successfully get a response from Apple by calling
AppleAuthentication.signInAsync as it mentioned in the documentation.
The problem occurs when I turn to the backend to convert Apple auth code to an internal token my app works with. For doing that, I send a request to an endpoint on my backend sending an authorization_code gotten from the Apple Auth.
Then my backend sends a request to https://appleid.apple.com/auth/token:
'client_id': <App ID>, 'client_secret': <client_secret>, 'code': <Code received from iOS app>, 'grant_type': 'authorization_code'
And I get 400 invalid_grant from Apple on the backend.
Is there anything I’m missing in the app or on the backend?
How to fix that out?
