Use `blnk.api_keys.delete` to revoke an [API key](/advanced/secure-blnk) by ID.
```python blnk.api_keys.delete wrap theme={"system"}
response = blnk.api_keys.delete("api_key_abc123", {
"owner": "merchant_a",
})
```
| Field | Type | Description |
| :------ | :---- | :------------------------------------------------------------------ |
| `id` | `str` | ID of the API key to revoke. |
| `owner` | `str` | Owner of the key. Required when authenticating with the master key. |
On success, Core returns `204 No Content` and `response.data` is `None`. The key can no longer authenticate requests.
```json 204 No Content wrap theme={"system"}
{}
```
Returns `204 No Content` on success with an empty body, so `response.data` is `None`.
