`Header` is a "sister" class of `Path`, `Query` and `Cookie`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Header`, and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare headers, you need to use `Header`, because otherwise the parameters would be interpreted as query parameters.

///

* `@app.delete()`
* etc.

{* ../../docs_src/response_status_code/tutorial001.py hl[6] *}

/// note

Notice that `status_code` is a parameter of the "decorator" method (`get`, `post`, etc). Not of your *path operation function*, like all the parameters and body.

///

The `status_code` parameter receives a number with the HTTP status code.

## Використання `BackgroundTasks`

Спочатку імпортуйте `BackgroundTasks` і додайте його як параметр у Вашу *функцію операції шляху* (path operation function) до `BackgroundTasks`:

{* ../../docs_src/background_tasks/tutorial001.py hl[1,13] *}

**FastAPI** автоматично створить об'єкт `BackgroundTasks` і передасть його у цей параметр.

Esto también significa que si estás dentro de una función de utilidad que estás llamando dentro de tu *path operation function*, y lanzas el `HTTPException` desde dentro de esa función de utilidad, no se ejecutará el resto del código en la *path operation function*, terminará ese request de inmediato y enviará el error HTTP del `HTTPException` al cliente.

# Response Cookies { #response-cookies }

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function*.

And then you can set cookies in that *temporal* response object.

{* ../../docs_src/response_cookies/tutorial002.py hl[1, 8:9] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).
