## Імпорт `Form`

Імпортуйте `Form` з `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

## Оголошення параметрів `Form`

Створюйте параметри форми так само як Ви б створювали `Body` або `Query`:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[9] *}

Наприклад, один зі способів використання специфікації OAuth2 (так званий "password flow") вимагає надсилати `username` та `password` як поля форми.

Dort können Sie einstellen:

Beachten Sie, dass die Query `token` von einer Abhängigkeit verarbeitet wird.
