Feature Description

Cloud Infinite supports customizing a callback URL. After task completion, the system sends an HTTP POST request to this URL with notification content in the request body. You can confirm it by the configured callback URL to promptly learn about task processing progress and status so that you can perform other business operations.

Callback Content

After task completion, the system will send the callback content to the callback URL you have set, showing the complete node data as follows:
