## Добавление фоновой задачи { #add-the-background-task }

Внутри вашей функции‑обработчика пути передайте функцию задачи объекту фоновых задач методом `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[14] *}

`.add_task()` принимает следующие аргументы:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[6:9] *}
