You can easily integrate external components with Leapwork using the open REST API exposed on the Controller. In order for the specific component to gain access to Leapwork, an **API key** is required.

**Note:** API Access Keys settings would be available if you are logged in as an administrator.

## Adding an API Access Key

1. Go to **Settings** and select **API Access Key**.
2. Click **Add Key**.
3. Enter the required comments and select the appropriate **scope**.
4. Click **Generate Key**.
5. Click **Add** to create the key.

## Managing API Access Key Scopes

When adding a new API Access Key, you can manage permissions efficiently using a **Select/Deselect all** checkbox:

- Selecting this option grants all scopes.
- If any scope is deselected after selecting all, the **Select/Deselect all** checkbox unchecks automatically.
- If users select all individual scopes manually, the **Select/Deselect all** checkbox checks automatically. This enhancement simplifies API key management and improves control over access permissions.
- Use the comment field to identify which external component is using the generated key.

Please see [REST API Documentation](https://docs.leapwork.com/leapwork-flow/latest/public-rest-apis) for more detailed instructions on how to use the REST API and the API Access keys.
