Bei Bedarf können Sie OpenAPI mithilfe von Einstellungen und Umgebungsvariablen abhängig von der Umgebung bedingt konfigurieren und sogar vollständig deaktivieren.

## Über Sicherheit, APIs und Dokumentation

Das Verstecken Ihrer Dokumentationsoberflächen in der Produktion *sollte nicht* die Methode sein, Ihre API zu schützen.
