# Header-параметри

Ви можете визначати параметри заголовків, так само як визначаєте `Query`, `Path` і `Cookie` параметри.

## Імпорт `Header`

Спочатку імпортуйте `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Оголошення параметрів `Header`

Потім оголосіть параметри заголовків, використовуючи ту ж структуру, що й для `Path`, `Query` та `Cookie`.

# Parámetros de Header

Puedes definir los parámetros de Header de la misma manera que defines los parámetros de `Query`, `Path` y `Cookie`.

## Importar `Header`

Primero importa `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declarar parámetros de `Header`

Luego declara los parámetros de header usando la misma estructura que con `Path`, `Query` y `Cookie`.

* Import `Jinja2Templates`.
* Create a `templates` object that you can reuse later.
* Declare a `Request` parameter in the *path operation* that will return a template.
* Use the `templates` you created to render and return a `TemplateResponse`, pass the name of the template, the request object, and a "context" dictionary with key-value pairs to be used inside of the Jinja2 template.

{* ../../docs_src/templates/tutorial001.py hl[4,11,15:18] *}
