# WebSockets

When defining WebSockets, you normally declare a parameter of type `WebSocket` and with it you can read data from the client and send data to it.

It is provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi import WebSocket
```

**FastAPI** will **extract** the data for **each field** from the **form data** in the request and give you the Pydantic model you defined.
