Example of Working with Push Notifications

To work with push notifications, create the PushActivity application, which uses the methods implemented in the PushAPI unit.

The application can be used to subscribe to messages with the specified topic and add a token to mobile platform server.

Before creating the PushActivity application set up the Firebase service and push notifications in the administrator console.

To set up push notifications in the administrator console, use the Push Notifications section:

Select the checkbox next to Firebase.
Enter the server key in the Authorization Key box. To get the key, open the Firebase console and open settings of the Cloud Messaging section, which stores project credentials.
Go to the Topics subsection and add a topic named topic1.
Go to the Templates subsection and add a template named template1:

Select the checkbox next to Firebase.
Enter the template {"notification":{"title":"{{title}}","body": "{{body}}"}} in the Template box.

After executing the operations create the PushActivity application.

To display the specified notification, execute the request:

$ curl -X POST  http://testmasterfmp.fsight.cloud/api/v1/push/send/template1/topic/topic1/
    -H 'Authorization: BearereyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJwcm9qZWN0X2lkIjo0LCJlbnZpcm9ubWV
        udCI6Ikxlb25pZF9lbnZpcm9ubWVudCIsInByb2plY3QiOiJMZW9uaWRfcHJvamVjdCIsInVzZXJuYW1lIjoiTGVvbmlk
        IiwiZGV2aWNlX2lkIjpudWxsLCJleHAiOjE1NDg2NzYzNzQsImlhdCI6MTU0NzQ2Njc3NH0.bdkjsWckjxZXgbFd8jpfF
        P7jyHoPy6KLAcDC6tue-18'
    -H 'Content-Type: application/json'
    -d '{"title": "Shakespeare", "body": "To be or not to be?"}'

After the request is executed, the notification is displayed on a mobile device.

To view sent messages, use the Messages subsection.

The text input area contains message topic name. The text input area is empty by default.
