Feature Overview

Cloud Infinite supports custom configuration of callback URLs. After a task is completed, the system sends an HTTP POST request to this URL, with the notification content in the request body. You can use the callback URL to learn about the task processing progress and status in a timely manner for other business operations.

Callback Content

After task completion, the system will send callback content to your configured callback address. The following shows the complete content of the node data:
