can somebody show me the way to integrate this in rails api while using react native. I am done with the mobile end that sends the authorization_code and email but confused at backend part.

I have done this a few times. The documentation here is lacking

@kamalpandey I plan on having this working tonight, and I'm forking to write docs now. I'll keep you posted.

Quick overview:

0) devise + doorkeeper + oidc + pkce 1) react-native-app-auth 2) fetch + Authorization header 3) omniauth apple setup 4) profit

@skotchpine any luck?

[skotchpine]

Oh yeah, no problem!

I know this doesn't answer MOST of this issue, but I think it answers covers the scope of this library #62

@skotchpine's guide does an excellent job of how to setup the library. I just wanted to expand on the final part, how to sync in-app credentials with the omniauth backend.

You need to pass some variables back to the omniauth callback endpoint.

const appleAuthRequestResponse = await appleAuth.performRequest({
  requestedOperation: appleAuth.Operation.LOGIN,
  requestedScopes: [appleAuth.Scope.EMAIL],
});

// get current authentication state for user
// /!\ This method must be tested on a real device. On the iOS simulator it always throws an error.
const credentialState = await appleAuth.getCredentialStateForUser(appleAuthRequestResponse.user);

// use credentialState response to ensure the user is authenticated
if (credentialState === appleAuth.State.AUTHORIZED) {
  // HERE:
  const serverResponse = await apiClient.perform("GET", "https://yourserver/auth/apple/callback", {
    type: "json",
    queryParams: {
      code: appleAuthRequestResponse.authorizationCode,
      state: appleAuthRequestResponse.state,
      id_token: appleAuthRequestResponse.identityToken,
      nonce: appleAuthRequestResponse.nonce,
      user: JSON.stringify({
        email: appleAuthRequestResponse.email
      })
    }
  });

  if (serverResponse.success) {
    alert("Done")
  }
}

Replace apiClient.perform with your preferred way of sending requests to your server (fetch for example).

I'd also like to add that I have been very pleased with this library: https://github.com/FormidableLabs/react-native-app-auth

I think this issue is really out of scope for this library. If you'd like more advice, I'd be glad to do a call. My email is: tycinnamon@gmail.com

To be clear: I'd recommend closing the issue.
