### Other utility functions { #other-utility-functions }

Any other utility function that you call directly can be created with normal `def` or `async def` and FastAPI won't affect the way you call it.

This is in contrast to the functions that FastAPI calls for you: *path operation functions* and dependencies.

* nerd: умник
* sub application: подприложение
* webhook request: вебхук-запрос
* serve (meaning providing access to something): «отдавать» (or `предоставлять доступ к`)
* recap (noun): резюме
* utility function: вспомогательная функция
