# OpenAPI Webhooks { #openapi-webhooks }

There are cases where you want to tell your API **users** that your app could call *their* app (sending a request) with some data, normally to **notify** of some type of **event**.

This means that instead of the normal process of your users sending requests to your API, it's **your API** (or your app) that could **send requests to their system** (to their API, their app).

This is normally called a **webhook**.

# Alt Uygulamalar - Mount İşlemi { #sub-applications-mounts }

Kendi bağımsız OpenAPI şemaları ve kendi dokümantasyon arayüzleri olan iki bağımsız FastAPI uygulamasına ihtiyacınız varsa, bir ana uygulama oluşturup bir (veya daha fazla) alt uygulamayı "mount" edebilirsiniz.

3. If the daemon is not able to run the request, for example it is already running a request or is shutting down, it rejects the request. The client starts again.
4. The daemon runs the request, sending back data such as logging output or tooling API events and intermediate models while doing so.
