# Cancel Call

DELETE https://api.pinnacle.sh/calls/{id}

End a live call. Terminal calls are returned unchanged.

Reference: https://docs.pinnacle.sh/api-reference/calls/lifecycle/cancel-call

## Authentication

- `PINNACLE-API-KEY` header (required) — API Key authentication via header

## Request

### Path parameters

- `id` (string, required) — Pinnacle call ID.

## Response

### 200

Canceled call.

- `id` (string, required)
- `state` (enum, required) — Current voice call lifecycle state. This field is named `state` on Call objects and `status` on `CALL.STATUS` webhook payloads. - `INITIATED`: Pinnacle accepted the call request and is setting up the call with the voice provider. - `RINGING`: The call is ringing and has not been answered yet. - `ANSWERED`: The call has been answered and is active. - `BRIDGED`: The call is connected to another call leg, such as after a transfer or bridge command. - `ENDED`: The call ended normally. - `FAILED`: The call could not be established or could not continue because of a provider or system failure. - `NO_ANSWER`: The call rang until timeout without being answered. - `BUSY`: The destination was busy. - `CANCELED`: The call was canceled before normal completion.
  - Allowed values: `INITIATED`, `RINGING`, `ANSWERED`, `BRIDGED`, `ENDED`, `FAILED`, `NO_ANSWER`, `BUSY`, `CANCELED`
- `direction` (enum, required) — Direction of the call relative to your Pinnacle team. - `INBOUND`: The call originated from an external caller and was received by one of your Pinnacle voice-enabled phone numbers. - `OUTBOUND`: The call was created from Pinnacle and dialed out from one of your voice-enabled phone numbers.
  - Allowed values: `INBOUND`, `OUTBOUND`
- `to` (string, required)
- `from` (string, required)
- `created_at` (string, required)
- `started_at` (string, required, nullable)
- `answered_at` (string, required, nullable)
- `ended_at` (string, required, nullable)
- `metadata` (map from string to string, required)
- `record` (boolean, required) — Whether recording was requested when this call was created. This is intent, not progress. `recording_state` says what happened to the audio; `record` says whether any was ever asked for. A call with `record: true` and `recording_state: null` after it has ended means a recording was expected but never produced.
- `recording_state` (enum, required, nullable) — If no recording has been captured or enabled for the call, then `null`.
  - Allowed values: `PENDING`, `READY`, `FAILED`, `DELETED`
- `hangup_cause` (string, required, nullable)
- `conference_id` (string, optional, nullable) — The conference this call is in, or was most recently in; `null` if never. Returned by `GET /calls/{id}`.
