Bug Request failed: 401 on iOS

Hello,

I've been using Authentication for Cloud Save for some time on Unity Editor & Android devices, however, when following the official tutorials for Apple Sign In on iOS, I'm unable to authenticate on iOS devices. I was unable to find any possible solution to this. I'm getting the Apple user ID, I get these errors on my device when using

await AuthenticationService.Instance.SignInWithAppleAsync(idToken);

Code (CSharp):

1. [Authentication]: Request failed: 401, {"title":"PERMISSION_DENIED","detail":"validation failed","details":[],"status":401}

Thank you for your reply!

I set the "Sign-in with Apple" identity provider with my app's bundle ID (following these instructions https://docs.unity.com/authentication/SettingupAppleSignin.html), should the app's Apple ID be used instead (the 10-digit number)?

As for the ID token from Apple, I was following the instructions for the Sign-in with Apple Unity plugin, as well as their code examples, so I should be sending the proper ID token. You can see the script responsible for the Apple sign-in in the attachments.

My Unity project ID is:

ac414d21-51f4-418d-b8ad-0c0b8bf05799

 

Is it possible that my issue is caused by this bug?
https://issuetracker.unity3d.com/is...U9IR_G8tWY-SeKf7DW1f4XJ4zLk6r29TwqGc81n4ERzHI

 

So, I've tried to build the app on Unity Editor 2021.3.6f1 (where the bug mentioned above should be already fixed), but I get the exact same error. I've also tried to set the app id to the Apple ID number, but no change. Any chance to get help on that?

 

In another test, I tried anonymous authentication and I was able to log in successfully. So there must be an issue with either the code implementation I'm using or with the identity configuration. Could somebody please take a look?

 

Same exact issue here. I am able to login using Google Play Service (on Android devices of course) and Anonymous. When trying AppleSigIn, I correctly manage to retrieve the credential token, but I get a "Request failed: 401 {"title":"PERMISSION_DENIED","detail":"validation failed","details":[],"status":401}" when calling SignInWithAppleAsync

Of course I authorized Apple SigIn in the authentication services.
I both tried to use the 10 digit code and the bundle ID as Application ID with the same results.

I am on 2021.3.7f1

 

I figured it out! We were both using a wrong implementation.
SignInWithAppleAsync requires an id token and we were passing the "credential.User" because of the code examples.

Still trying, but I think I am on the right track. The correct way to get the idToken should be:

Code (CSharp):

1. System.Text.Encoding.ASCII.GetString((credential as IAppleIDCredential)?.IdentityToken);

Hope it helps.

 

This seems to be the correct solution, thank you very much!

 

Glad it helped

 

I had the same issue and fixed it thanks to your answer, thank you!
I based mine on the lupidan Apple Sign in and was connecting it to a Unity Gaming Services account. I used part of the following code to link to a signed in account
var appleIdCredential = receivedCredential as IAppleIDCredential;
if (appleIdCredential.IdentityToken != null)
{
var identityToken = Encoding.UTF8.GetString(appleIdCredential.IdentityToken, 0, appleIdCredential.IdentityToken.Length);
LinkWithAppleAsync(identityToken);
.....

async Task LinkWithAppleAsync(string idToken)
{
try
{
await AuthenticationService.Instance.LinkWithAppleAsync(idToken);
Debug.Log("Link is successful.");
}
.....
