Task Callback

Ukuran font
Terakhir diperbarui: 2025-09-15 17:39:16
Feature Description
Cloud Infinite supports customizing a callback URL. After task completion, the system sends an HTTP POST request to the URL with the notification content in the request body. You can confirm it by the configured callback address to promptly learn about task processing progress and status so that other business operations can be performed.
Callback Content
After task completion, the system will send callback content to the callback URL you have set. The response body is returned as application/xml. An example including the complete node data is shown below:
