If a client tries to send some **extra cookies**, they will receive an **error** response.

Poor cookie banners with all their effort to get your consent for the <dfn title="This is another joke. Don't pay attention to me. Have some coffee for your cookie. ☕">API to reject it</dfn>. 🍪

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/request_form_models/tutorial002_an_py310.py hl[12] *}

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`
