Note: This parameter is intended exclusively for YouTube content partners. The onBehalfOfContentOwner parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and get access to all their video and channel data, without having to provide authentication credentials for each individual channel. The actual CMS account that the user authenticates with must be linked to the specified YouTube content owner.

Note: The API server only processes the parameter value if the request contains an updated caption file. The sync parameter indicates whether YouTube should automatically synchronize the caption file with the audio track of the video. If you set the value to true, YouTube will automatically synchronize the caption track with the audio track.
