Вы также определяете, в какие моменты (при каких событиях) ваше приложение будет отправлять эти запросы.

А ваши пользователи каким-то образом (например, в веб‑панели) указывают URL-адрес, на который ваше приложение должно отправлять эти запросы.

Вся логика регистрации URL-адресов для вебхуков и код, который реально отправляет эти запросы, целиком на вашей стороне. Вы пишете это так, как вам нужно, в своем собственном коде.
