Generating Firebase Cloud Messaging (FCM) Server Key and Sender ID for Android Devices

The first step in the installation and configuration of the sample Engagement application on an Android device is the generation of the sender ID. Android devices use the sender ID to register with FCM and receive notifications.

Open the Google developer's console window by logging into: https://console.firebase.google.com/

The Google Developer’s account Sign in page appears.
Enter your Google credentials. Click Sign in to continue.

The Welcome to Firebase page appears.
Click Create New Project.

The Create a project dialog box appears.
Enter details for the following fields:
- Project name: Enter the project name. Based on the project name, the system generates the project ID. The project name is used in the Google console and the project ID identifies the project name.
- Country/region: Select the required country from the drop-down list.
Cancel: Click Cancel to close the Create a project dialog box.
Enter the required details. Click Create Project to continue.

The Welcome to Firebase! Get started here page appears.
Click the wheel icon next to the Engagement Services Demo App label in the left menu bar.

The Project settings drop-down list appears.
Click Project Settings from the drop-down list.

The Settings page appears. Here you can view the Project name, Public- facing name, Project ID, and the Web API Key for your reference.

You can edit the Project name and the Public-facing name.
Under Settings, click the Cloud Messaging tab next to the General tab.
The Project credentials section appears. The Project credentials section displays the Firebase Cloud Messaging token, Sender ID, and the Server key.
Copy the Sender ID. You use the Sender ID in the client-side application to register to FCM from the device.
Copy the Server Key. You use the Server Key in the Engagement server while creating an application.
