The `websocket_api` component set up a WebSocket API and allows one to interact with a Home Assistant instance that is running headless. This component depends on the [`http` component](/components/http/).

<p class='note warning'>
It is HIGHLY recommended that you set the `api_password`, especially if you are planning to expose your installation to the internet.
</p>

```yaml
# Example configuration.yaml entry
websocket_api:
```

For details to use the WebSocket API, please refer to the [WebSocket API documentation](/developers/websocket_api/) .
