Webhook event catalog

Nine event types are available to subscribe to. Every payload includes tenant_id and trace_id for correlating events from the same call.

Call events

`call.originated`

Fires when a call origination starts.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "direction": "outbound",
  "caller_id": "+14155550100",
  "destination": "+14155550101",
  "node_id": "...",
  "timestamp": "2026-08-05T14:30:00Z",
  "variables": {}
}

`call.answered`

Fires when a call is answered.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "answered_by": "agent_id",
  "timestamp": "2026-08-05T14:30:05Z"
}

answered_by is one of agent_id (an agent’s ID), ivr, or ai_agent.

`call.bridged`

Fires when two call legs are connected.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "leg_a_id": "...",
  "leg_b_id": "...",
  "timestamp": "2026-08-05T14:30:06Z"
}

`call.hangup`

Fires when a call ends.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "hangup_cause": "NORMAL_CLEARING",
  "duration_ms": 125000,
  "timestamp": "2026-08-05T14:32:11Z"
}

`call.recording`

Fires when a recording is saved.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "recording_url": "...",
  "duration_ms": 125000,
  "format": "wav",
  "size_bytes": 2004480,
  "timestamp": "2026-08-05T14:32:12Z"
}

`call.dtmf`

Fires per keypress during a live call. Delivered at-most-once — not retried like other events, since a missed keypress isn’t worth a retry storm.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "digit": "1",
  "duration_ms": 120,
  "timestamp": "2026-08-05T14:30:20Z"
}

`call.amd_result`

Fires when answering machine detection completes.

{
  "tenant_id": "...",
  "call_id": "...",
  "trace_id": "...",
  "result": "human",
  "timestamp": "2026-08-05T14:30:04Z"
}

result is one of human, machine, uncertain, or no_answer.

Campaign events

`campaign.lead_state_changed`

Fires when a lead moves between states (fresh, attempted, contacted, closed) — see Lead fields.

`campaign.abandoned`

Fires when a connected call is abandoned — no agent became available before the connect window elapsed.

Field-level payload examples for the two campaign events above aren’t published yet — check back, or capture one from a real delivery in your own test webhook.
