# Form Data

Cuando necesitas recibir campos de formulario en lugar de JSON, puedes usar `Form`.

/// info | Información

Para usar forms, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install python-multipart

# Form Data { #form-data }

When you need to receive form fields instead of JSON, you can use `Form`.
