I'm trying to use Firebase to handle authentication with Facebook logins. I've created the activity by following the documentation on both Firebase's and Facebook's sites and making sure the settings on both sites are filled as needed.
I'm able to log in to Facebook from my app, but when it comes to Firebase saving the user, I get an error:
signInWithCredential com.google.firebase.FirebaseException: An internal error has occurred. [ Access Not Configured. Google Identity Toolkit API has not been used in project 27973105972 before or it is disabled. Enable it by visiting https ]
On Firebase I have for Sign-in providers: Facebook enabled with correct App ID and App secret.
On Facebook I have added the Firebase's redirect URI to the Valid OAuth redirect URIs list.
As a note, searching for Google Identity Toolkit API, leads me to https://developers.google.com/identity/toolkit/ where it says to use Firebase Authentication. So not a very helpful error message.
