Webhook Events

Call transcript segment event

One final segment of a live call transcript.

When it fires

Only for teams with zero content retention, on calls with transcription on: once per final segment, while the call is live. Zernio stores no transcript for these teams, so it cannot be fetched later. Store each segment when it arrives.

Payload notes

segment.text is the final text, segment.confidence the recognition confidence and segment.at when it was transcribed.

postWebhookcall.transcript_segment

Payload

testboolean

Always true when present: only a sample sent by POST /v1/webhooks/test with an event carries it. Real deliveries never do.

idstring required

Stable webhook event ID: the dedupe key, also sent as the X-Zernio-Event-Id header and identical on every retry and redelivery. It identifies the event only, never an account or other resource.

event'call.transcript_segment' required

timestampstring date-time required

UTC time at which Zernio generated this event (set once when the event payload is built, before delivery is queued). Retries and redeliveries keep the original value, so it reflects the event, not the delivery attempt.

Example payload

{
  "profiles": [
    {
      "externalId": "tenant_42"
    }
  ]
}

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
