Meeting Closed Captions APIs are enabled upon request, and are not available by default. Please contact the Webex
Developer Support team at devsupport@webex.com if you would like to enable this feature for your organization.
Meeting closed captions are the automatic transcriptions of what is being said during a meeting in real-time.
Closed captions appear after being enabled during a meeting and can be translated to a participant’s language.
A closed caption snippet is a short text snippet from a meeting closed caption which was spoken by a particular
participant in the meeting. A meeting’s closed captions consists of many snippets.
The Closed Captions API manages meeting closed captions and snippets. You can list meeting closed captions, as well
as list and download snippets. Closed captions can be retrieved in either Web Video Text Tracks (VTT) or plain text
(TXT) format via the download links provided by the vttDownloadLink and txtDownloadlink response properties,
respectively.
Refer to the Meetings API Scopes section of Meetings Overview guide for the scopes required for each API.
