The Recording.MP4.Available webhook event is sent when the recorded conference in the MP4 format is ready and can be downloaded through the included URL link. The webhook event is available for Dolby Voice and non-Dolby Voice conferences:

  • Dolby Voice conferences: The webhook event includes the link to the MP4 recording.
  • Non-Dolby Voice conferences: The webhook event can include links to the MP3 and MP4 recordings, depending on the selected recording format. The BOTH recording option allows receiving links to MP3 and MP4 recordings and does not allow receiving separate recordings for selected conference participants (split recording). If the BOTH option is selected, the webhook event contains the links to both the MP3 and MP4 files separated by the | character.

Note: Due to S3 high availability replication, webhook events may experience mild latency, as it takes time to replicate across S3 servers. Files on S3 should be available within milliseconds after the webhook is sent. However, we recommend implementing a back-off retry mechanism, in the event that the file download fails.
