Events

Understand the webhook delivery envelope and event subscriptions.

Webhook deliveries use an event envelope shaped as:

{
  "id": "<event id>",
  "type": "call.answered",
  "occurred_at": "2026-01-01T00:00:00Z",
  "data": {}
}

The data field contains the event-specific payload.

Voice-related event families currently include calls, recordings, conferences, and trunk lifecycle events. Subscribe only to event types your integration processes.
