// The intention here is to use 64-78 in a way that matches the attempt in
// sysexits to signify some error running istioctl, and use 79-125 as custom
// error codes for other info that we'd like to use to pass info on.
const (

In that case, **FastAPI** also provides you with the tools to build it.

When we create an instance of the `OAuth2PasswordBearer` class we pass in the `tokenUrl` parameter. This parameter contains the URL that the client (the frontend running in the user's browser) will use to send the `username` and `password` in order to get a token.

There are 2 main differences from a normal *path operation*:

* It doesn't need to have any actual code, because your app will never call this code. It's only used to document the *external API*. So, the function could just have `pass`.

## Return a `Response` directly

You can also add headers when you return a `Response` directly.

Create a response as described in [Return a Response Directly](response-directly.md){.internal-link target=_blank} and pass the headers as an additional parameter:

```Python hl_lines="10-12"
{!../../docs_src/response_headers/tutorial001.py!}
```
