# Delete an Application

> Permanently delete a Vobiz voice application by app_id - removes all webhook configuration and disassociates attached phone numbers and SIP endpoints.

```http theme={null}
DELETE https://api.vobiz.ai/api/v1/Account/{auth_id}/Application/{app_id}/
```

Permanently deletes an application.

<Info>
  **Authentication required:**

  * `X-Auth-ID` - Your account Auth ID
  * `X-Auth-Token` - Your account Auth Token
  * `Content-Type: application/json`
</Info>

<Warning>
  **Warning:** Deletion is permanent and cannot be undone. If the application is associated with phone numbers, the deletion is blocked with a `409` until those associations are removed.
</Warning>

<Note>
  **Delete an app that is in use:** first [detach every number](/applications/detach-number) bound to it (and repoint any endpoints whose `application` is this app, via [update endpoint](/endpoint/update-endpoint)), then call delete. Deleting a `default_number_app`/`default_endpoint_app` removes the auto-routing default - set a new default on another application beforehand if you rely on it.
</Note>
