Pushing a Device Deletion Notification

Typical Scenario

After an application subscribes to device deletion notifications (the notification type is deviceDeleted) on the platform, the platform sends a notification to the application when the device is deleted from the platform.

API Function

This API is used by the platform to push notifications to an application that has subscribed to device deletion notifications.

Note

1. When subscribing to platform service data, an application must subscribe to the specified callback URL in the API description. The server and port in the callback URL are the public IP address and specified port of the application.

2. An application receives the content of a push message by inheriting the PushMessageReceiver class and overriding the callback API.

3. If the callback URL is not the address of the application, the application must implement the original callback API. For details on the API content, see Message Push in the Northbound API Reference.
