## 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.
