Pushing Device Shadow Status Change Notifications
Typical Scenario
After an NA subscribes to device shadow status change notifications (the notification type is deviceDesiredPropertiesModifyStatusChanged) on the IoT platform, the IoT platform sends a notification message to the NA when the device shadow on the IoT platform succeeds or fails to synchronize data to the device.
API Function
This API is used by the IoT platform to push notification messages to an NA that has subscribed to device shadow status change notifications.
Note
The NA must return a response code after receiving a message pushed by the IoT platform.
