DescribeTasks

1. API Description

Domain name for API request: mps.tencentcloudapi.com.

This API is used to query tasks.
If the data is large, one API call may not be able to obtain all the tasks in the query. You can use the ScrollToken parameter to query tasks with multiple calls.
Only tasks in the last seven days (168 hours) can be queried.

A maximum of 100 requests can be initiated per second for this API.

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
