    1. API Description

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

    • This API is used to query the task list;
    • If there are many data entries in the list, one single call of the API may not be able to pull the entire list. The ScrollToken parameter can be used to pull the list in batches;
    • Only tasks in the last three days (72 hours) can be queried.

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