### Gerar o esquema OpenAPI { #generate-the-openapi-schema }

Em seguida, use a mesma função utilitária para gerar o esquema OpenAPI, dentro de uma função `custom_openapi()`:

{* ../../docs_src/extending_openapi/tutorial001_py39.py hl[2,15:21] *}

### Modificar o esquema OpenAPI { #modify-the-openapi-schema }

### API-Dokumentation { #api-docs }

Wenn Sie zu `/docs` gehen, sehen Sie, dass es die **Schemas** für die Daten enthält, die in Requests gesendet und in Responses empfangen werden:

<img src="/img/tutorial/generate-clients/image01.png">

Sie können diese Schemas sehen, da sie mit den Modellen in der App deklariert wurden.

Diese Informationen sind im **OpenAPI-Schema** der Anwendung verfügbar und werden in der API-Dokumentation angezeigt.

### Documentação da API { #api-docs }

Se você for para `/docs`, verá que ela tem os **schemas** para os dados a serem enviados nas requisições e recebidos nas respostas:

<img src="/img/tutorial/generate-clients/image01.png">

Você pode ver esses schemas porque eles foram declarados com os modelos no app.

Essas informações estão disponíveis no **schema OpenAPI** do app e são mostradas na documentação da API.
