//// tab | Pydantic v1

У версії Pydantic 1 використовується внутрішній клас `Config` і параметр `schema_extra`, як описано в <a href="https://docs.pydantic.dev/1.10/usage/schema/#schema-customization" class="external-link" target="_blank">документації Pydantic: Налаштування схеми</a>.

这部分代码很常规，您对绝大多数代码应该都比较熟悉了：

/// tip | 提示

`callback_url` 查询参数使用 Pydantic 的 <a href="https://pydantic-docs.helpmanual.io/usage/types/#urls" class="external-link" target="_blank">URL</a> 类型。

此处唯一比较新的内容是*路径操作装饰器*中的 `callbacks=invoices_callback_router.routes` 参数，下文介绍。

## 存档回调

实际的回调代码高度依赖于您自己的 API 应用。

并且可能每个应用都各不相同。
