## Die Dokumentation testen { #check-the-docs }

Sie können die Query-Parameter in der Dokumentations-Oberfläche unter `/docs` einsehen:

<div class="screenshot">

</div>

## Zusätzliche Query-Parameter verbieten { #forbid-extra-query-parameters }

## Check the Docs { #check-the-docs }

You can see the query parameters in the docs UI at `/docs`:

<div class="screenshot">

</div>

## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.
