Давайте рассмотрим это на примере.

Представьте, что вы разрабатываете приложение, позволяющее создавать счета.

Эти счета будут иметь `id`, `title` (необязательный), `customer` и `total`.

Пользователь вашего API (внешний разработчик) создаст счет в вашем API с помощью POST-запроса.

Затем ваш API (предположим) сделает следующее:

* Отправит счет клиенту внешнего разработчика.
* Получит оплату.
