constraints.NotNull.message = {item} is required.
constraints.Null.message = {item} must be null.
constraints.Past.message = {item} must be a past value.
constraints.Pattern.message = {item} does not match "{regexp}".
constraints.Size.message = The size of {item} must be between {min} and {max}.

* das Geld einsammeln.
* eine Benachrichtigung an den API-Benutzer (den externen Entwickler) zurücksenden.
    * Dies erfolgt durch Senden eines POST-Requests (von *Ihrer API*) an eine *externe API*, die von diesem externen Entwickler bereitgestellt wird (das ist der „Callback“).

## Die normale **FastAPI**-Anwendung

Sehen wir uns zunächst an, wie die normale API-Anwendung aussehen würde, bevor wir den Callback hinzufügen.

    * Hier übergeben wir die Klasse, die Gunicorn etwa so importiert und verwendet:

        ```Python
        import uvicorn.workers.UvicornWorker
        ```

* `--bind`: Das teilt Gunicorn die IP und den Port mit, welche abgehört werden sollen, wobei ein Doppelpunkt (`:`) verwendet wird, um die IP und den Port zu trennen.
