# Delete a link

> Permanently delete one short link by its public ID.

Permanently delete one link from the workspace bound to your API key. This
endpoint accepts one public `biq_lnk_...` ID; it does not accept numeric IDs or
comma-separated batches.

<Warning>
  Deletion cannot be undone. The link stops redirecting immediately, its
  attached QR file is removed, and associated link data is cleaned up.
</Warning>

## Authentication and permission

Send a workspace API key with **Links: Write** (`links.delete`). You do not send
a workspace ID.

```bash theme={null}
curl --request DELETE \
  --url https://biq.li/api/v1/link/biq_lnk_01M14D2M8VFKYQCE7Z3A6HRXWP \
  --header 'Authorization: Bearer biqli_your_workspace_api_key' \
  --header 'Accept: application/json'
```

| Path parameter | Type             | Description                                |
| -------------- | ---------------- | ------------------------------------------ |
| `link`         | string, required | Public link ID with the `biq_lnk_` prefix. |

## Response

A successful deletion returns `204 No Content` with an empty response body.
Deleting the same public ID again returns `404 resource_not_found`, so clients
can distinguish a completed deletion from a link that still exists.

## Errors

```json theme={null}
{
  "error": {
    "code": "resource_not_found",
    "message": "The link was not found in this workspace."
  },
  "request_id": "ae437f49-30a3-4d55-bca6-dc523f2efcb3"
}
```

| HTTP status | Error code              | Meaning                                                         |
| ----------- | ----------------------- | --------------------------------------------------------------- |
| `401`       | `invalid_token`         | The API key is missing, invalid, malformed, or revoked.         |
| `403`       | `insufficient_scope`    | The key lacks `links.delete` or its user lost workspace access. |
| `404`       | `resource_not_found`    | The ID is malformed, deleted, or unavailable in this workspace. |
| `429`       | `rate_limit_exceeded`   | The workspace exceeded its API request limit.                   |
| `500`       | `internal_server_error` | An unexpected server error occurred.                            |

The same `request_id` is returned in the `X-Biq-Request-Id` response header.

## Shared API behavior

Authentication is workspace-scoped; see [Authentication](/docs/api-reference/authentication). Errors use the standard envelope and request IDs described in [Errors](/docs/api-reference/errors), and requests are subject to [Rate limits](/docs/api-reference/rate-limits).
