How do I get the Firebase Registration Token

[pjcjonas]

On Courier we need the firebase registration token to send notifications via firebase: https://www.courier.com/docs/guides/providers/push/firebase-fcm/?configuration-requirements#profile-requirements

This references the following section on the Firebase docs: https://firebase.google.com/docs/cloud-messaging/js/first-message#access_the_registration_token

How would I get this token in the GodotFirebase for Godot addon? I am able to send user login info to my firebase app, but what then?

If you signup a user through GodotFirebase
https://github.com/GodotNuts/GodotFirebase/wiki/Authentication-and-User-Management#signup-with-email
You can access the registration token directly connecting to the signup_succeeded(auth_info : Dictionary) signal.
auth_info will contain an idtoken key

I shall implement and let you know... Thank you for the response! @fenix-hub

So when doing the sign up with this:

Firebase.Auth.signup_with_email_and_password("[email protected]", "123456")

I get the following response on the Auth:

{email:[email protected], expiresIn:3600, idToken:eyJhbGciOiJSUzI1NiIsImtpZCI6Ijk1M{ { ............. } }6Wll4iw, kind:identitytoolkit#SignupNewUserResponse, localId:{ { ............. } }6BjiaN2, refreshToken:AOkPPWSCYIZRaxw9dB{ { ............. } }Os3jRYMisCWGsRQ}

And when I pass in the the response from the provider is as follows:

"provider": "firebase-fcm",
  "providerResponse": {
    "data": {
      "error": {
        "code": 400,
        "message": "The registration token is not a valid FCM registration token",
        "status": "INVALID_ARGUMENT",
        "details": [
          {
            "@type": "type.googleapis.com/google.firebase.fcm.v1.FcmError",
            "errorCode": "INVALID_ARGUMENT"
          }
        ]
      }
    },
    ```

Ok so I suppose you need to deal with Google FCM APIs instead of Firebase ones to get that token.
I think it is a different set of APIs, unrelated to Firebase itself but they belong to Firebase Cloud Messaging (which is Google's Push Notification Broker). In that case I'm afraid we don't support them. Or at least I'm not aware of valid FCM tokens that Firebase API's can generate based on your Firebase users.

I think that the registration token the docs are referring to is related to the token generated by the FCM SDK when a user authorizes to receive Push Notifications on their devices.
If that is the case, indeed you need the FCM SDK, which we don't support (yet).
As far as there are some REST APIs however, we can help you with them.
