## Integriert in OpenAPI

Alle Requestdeklarationen, -validierungen und -anforderungen Ihrer Abhängigkeiten (und Unterabhängigkeiten) werden in dasselbe OpenAPI-Schema integriert.

Die interaktive Dokumentation enthält also auch alle Informationen aus diesen Abhängigkeiten:

"Mounting" means adding a complete "independent" application in a specific path, that then takes care of handling all the sub-paths.

This is different from using an `APIRouter` as a mounted application is completely independent. The OpenAPI and docs from your main application won't include anything from the mounted application, etc.

You can read more about this in the [Advanced User Guide](../advanced/index.md){.internal-link target=_blank}.
