## Add the background task { #add-the-background-task }

Inside of your *path operation function*, pass your task function to the *background tasks* object with the method `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[14] *}

`.add_task()` receives as arguments:

* A task function to be run in the background (`write_notification`).
