The Firebase Messaging C++ Sample (hereafter the 'test app') demonstrates receiving messages from Firebase Cloud Messaging using the Firebase C++ SDK. This application has no user interface and simply logs actions it's performing to the console.

NOTE: Do not implement the code changes of the subsequent linked instructions as this codebase already has those functionalities.

1. Complete Add Firebase to your C++ project for your selected build platforms.
2. Set up a Firebase Cloud Messaging client app with C++.

• Install and run the test app on your iOS or Android device or emulator.
• The application has minimal user interface. The output of the app can be viewed via the console:
  • iOS: Open select "View -> Debug Area -> Activate Console" from the menu in Xcode.
  • Android: View the logcat output in Android studio or by running adb logcat from the command line.
• When you first run the app, it will print: Received Registration Token: <code>. Copy this code to a text editor.

1. Navigate to the FCM REST API Docs for Method: projects.messages.send
2. Look for the "Try this method" panel
   1. This might require you to expand your browser window.
3. Follow the API doc to understand what IDs and fields to fill in for your particular use case.
   1. Your project number is available from Project settings
4. Fill in the Request body referencing the FCM REST API docs.
5. Execute.
6. Observe the command received in the app, via the console output.

Reminder, while this process is currently done from our website, it uses the FCM v1 Send API directly and provides the simplest starting point to switch to using the v1 Send API or the Firebase Admin SDK in production.
