# Delete all call data

> DELETE /v1/calls

Permanently erases **every** call on your API key - all call records, transcripts, analysis, recording files, and SMS messages. Intended for bulk erasure requests, offboarding a client, or clearing test data before going live.

## Request

```bash theme={null}
curl -X DELETE https://api.nixflex.com/v1/calls \
  -H "Authorization: Bearer KEY_ID:KEY_SECRET"
```

Or with the [SDK](https://www.npmjs.com/package/nixflex):

```javascript theme={null}
await client.calls.deleteAll();
```

The same action is available in the dashboard under **Settings → Delete call data**.

## Response

`200 OK`:

```json theme={null}
{
  "deleted": true,
  "calls_deleted": 412,
  "recordings_deleted": 389,
  "sms_deleted": 27
}
```

| Field                | Type   | Notes                                                                                              |
| -------------------- | ------ | -------------------------------------------------------------------------------------------------- |
| `calls_deleted`      | number | Call records removed.                                                                              |
| `recordings_deleted` | number | Recording files removed from storage. Lower than `calls_deleted` when some calls had no recording. |
| `sms_deleted`        | number | SMS messages removed.                                                                              |

Calls are deleted in batches, so a large history takes a few seconds. The response is returned once everything is gone.

## Not reversible

<Warning>
  This erases your entire call history in one request. There is no undo, no confirmation step, and no recovery window - export anything you need first with [List calls](/api-reference/calls/list). Database backups do not restore deleted recordings.
</Warning>

## What this does NOT do

* Your agents, phone numbers, and API keys are untouched - the platform keeps working exactly as before, with an empty history.
* Billing and invoices are unaffected. Past usage stays on your invoices; billing records are retained for tax purposes.
* To close the account itself, use account deletion in the dashboard, which purges this data and then removes your login.
