# Модели Header-параметров

Если у вас есть группа связанных **header-параметров**, то вы можете объединить их в одну **Pydantic-модель**.

Это позволит вам **переиспользовать модель** в **разных местах**, а также задать валидацию и метаданные сразу для всех параметров. 😎

/// note | Заметка

Этот функционал доступен в FastAPI начиная с версии `0.115.0`. 🤓

///

## Header-параметры в виде Pydantic-модели

And as the `Response` can be used frequently to set headers and cookies, **FastAPI** also provides it at `fastapi.Response`.
