Call GetVideoPlayAuth to obtain a playback credential for secure playback - ApsaraVideo VOD - Alibaba Cloud - ApsaraVideo VOD

Credentials are time-bound and file-specific—do not reuse across files. Expired or invalid credentials cause playback failures. Use this method for high-security playback scenarios.

Operation description

If a playback credential expires, you cannot retrieve the playback URL. You must obtain a new credential.
