    A sender ID is a project number created when you configure your API project. It is labeled Project Number in the Google Developers Console.

    In order to receive FIRMessaging messages, declare application:didReceiveRemoteNotification:

    Client apps can send upstream messages back to the app server using the XMPP-based Cloud Connection Server
