### Transfer Fields

| Field | Type | Description |
| :- | :- | :- |
| `event_type` | `string` | `transfer_completed`. |
| `transfer_initiated_at` | `datetime` | ISO timestamp when Altur recorded the transfer handoff starting. |
| `transfer_completed_at` | `datetime` | ISO timestamp when Altur recorded the transfer leg connecting. |

All other fields match the [`on_call_end`](https://docs.altur.io/api-reference/webhooks/on-call-end) call payload.

<Note>
  The payload describes the call at the moment of the transfer: `status` is
  `in-progress`, `answered_by` is `human`, and `ended_at`, `ended_by`, `ended_reason`, `duration` and
  `billed_duration` are `null`. The `transcript` contains the messages Altur has
  received up to the transfer; the last few lines spoken right before the
  transfer may occasionally be missing. Use `on_call_end` for the full
  transcript. The `end_user` and `campaign_user` objects reflect their values
  when the event is sent.
</Note>

Transfer webhooks do not support filters.

## Response Expectations
