Recorded Media​

Access recorded media from incidents:

  • Audio recordings
  • Photos and videos shared by callers
  • Livestream recordings

Media URLs are available via the Incident Events API and webhooks.

Authentication​

Live audio and transcript streaming require the incident_events scope.

For WebRTC audio streaming, you'll need a stream token obtained from:

POST /v1/incident_events/{id}/stream_token

See the Authentication guide for details.
