Obtaining Links for Downloading Error Logs (RDS for PostgreSQL)

Function

This API is used to obtain links for downloading error logs of a DB instance.

You need to call this API repeatedly until FINISH is returned for status.

Or, you can use the workflow_id value returned by the first API call to query the task status. After the task is successfully executed, call the API again to obtain the download link.

Before calling this API, learn how to authenticate it.
Before calling this API, learn about request header parameters.
