My data is a notification App.
You can create different channels within the App, and each channel will automatically generate an API that you can call anywhere, and then you can get related notifications on the current device.
Applicable scenarios:
1. Independent developers can add API requests to the purchase options in the App, so that they can push themselves every time someone buys, and there will be new purchases.
2. Join in the shortcut. The trigger condition is that the family members connect to wi-fi when they come back home.
