# Параметри заголовків { #header-parameters }

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

## Імпорт `Header` { #import-header }

Спочатку імпортуйте `Header`:

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

## Оголошення параметрів `Header` { #declare-header-parameters }

# Header Parameter Models { #header-parameter-models }

If you have a group of related **header parameters**, you can create a **Pydantic model** to declare them.

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

///

Déclarez les **paramètres d'en-tête** dont vous avez besoin dans un **modèle Pydantic**, puis déclarez le paramètre comme `Header` :

{* ../../docs_src/header_param_models/tutorial001_an_py310.py hl[9:14,18] *}

**FastAPI** extrait les données de **chaque champ** depuis les **en-têtes** de la requête et vous fournit le modèle Pydantic que vous avez défini.
