# Responses Adicionales en OpenAPI

/// warning | Advertencia

Este es un tema bastante avanzado.

Si estás comenzando con **FastAPI**, puede que no lo necesites.

///

Puedes declarar responses adicionales, con códigos de estado adicionales, media types, descripciones, etc.

Esos responses adicionales se incluirán en el esquema de OpenAPI, por lo que también aparecerán en la documentación de la API.

もしなんらかの理由でアンダースコアからハイフンへの自動変換を無効にする必要がある場合は、`Header`の`convert_underscores`に`False`を設定してください:

{* ../../docs_src/header_params/tutorial002.py hl[9] *}

/// warning | 注意

`convert_underscores`を`False`に設定する前に、HTTPプロキシやサーバの中にはアンダースコアを含むヘッダーの使用を許可していないものがあることに注意してください。

///

## ヘッダーの重複

受信したヘッダーが重複することがあります。つまり、同じヘッダーで複数の値を持つということです。

これらの場合、リストの型宣言を使用して定義することができます。
