To enable push messaging in your Android app, you need a project in Firebase (Google Messaging Service Platform). Firebase (FCM) allows you to send messages to users who have your app installed. For this, you will need a Sender ID and a Server key which are then stored in the Purple DS Manager.
Set up a Firebase project
Basically you need a Google account, eg email@example.com .
Please open the following link to Firebase Console .
1. Add a new Firebase project. (see images below)
2. You can choose a new project to manage the data of the connected app.
