"Операция" это один из "методов" HTTP.

Таких, как:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...и более экзотических:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

По протоколу HTTP можно обращаться к каждому пути, используя один (или несколько) из этих "методов".

При создании API принято использовать конкретные HTTP-методы для выполнения определенных действий.
