description: Volai webhooks deliver events about calls and SMS messages.
events:
- event: call.completed
description: The call ended, whether it had an agent or not; includes optional transcript, summary, captured data, durationSecs and priceHal.
- event: call.failed
description: The call ended in status "failed" with a technical reason; may include transcript, summary, durationSecs and priceHal for engine
errors.
- event: call.no_answer
description: An outbound call rang but the callee didn’t pick up (or a gate ring was declined).
- event: call.missed
description: An inbound call went unanswered or was turned away because all lines were busy.
- event: message.sent
description: The carrier accepted the SMS for sending (not a delivery receipt).
- event: message.received
description: A message arrived on your SMS number or calls‑and‑SMS number; includes id, from, to, body, segments and receivedAt.
delivery:
content_type: application/json; charset=utf-8
note: All events are sent as POST requests with a JSON envelope containing fields event, ts, event_id and data. The ts field is a millisecond
timestamp; the signature header (t=) is not documented on the page, so no signature mechanism is described. Delivery uses a retry queue for
call events and for message.received; other events are not explicitly described as retried.
