# Delete API key

`DELETE /apiKeys/{apiKeyId}`

Use the *Delete API keys* endpoint to delete an existing API key, providing its valid `id` as a parameter. Note that this operation is not reversible.

[API keys](https://docs.codat.io/platform-api#/schemas/apiKeys) are tokens used to control access to the API. Include this token in the `Authorization` header parameter when making API calls, following the word "Basic" and a space with your API key.

You can [read more](https://docs.codat.io/using-the-api/authentication) about authentication at Codat and managing API keys via the Portal UI or API.

### Tips and pitfalls

* It is possible to delete the last remaining API key. If this happens, a new key can be created via the [API key management page](https://app.codat.io/developers/api-keys) of the Portal.
* It is possible to delete the API key used to authenticate the *Delete API key* request.
