Question

How to get device tokens (FCM registration tokens) from Firebase?

I am making a mobile application using firebase and its server using node.js.

I want to send a message push notificationfrom the server, but I do not know how to get the device token.

• How to get device tokens from an external server? Now I am using the Firebase admin SDK.

• Is the device token only generated when the application connects to the fcm server?

• Do I have to save the token to another database when I first run the application and register the FCM server?

        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        //Log the token
        Log.d(TAG, "Refreshed token: " + refreshedToken);
    }
    private void sendRegistrationToServer(String token) {
        //Implement this method if you want to store the token on your server
    }
}
