この場合、その *外部 API* がどのようである「べき」かをドキュメント化したくなるでしょう。どんな *path operation* を持ち、どんなボディを受け取り、どんなレスポンスを返すか、などです。

## コールバックのあるアプリ { #an-app-with-callbacks }

例で見ていきます。

あなたが請求書を作成できるアプリを開発していると想像してください。

これらの請求書は `id`、`title`（任意）、`customer`、`total` を持ちます。

あなたの API の利用者（外部開発者）は、POST リクエストであなたの API に請求書を作成します。

その後、あなたの API は（仮にこうしましょう）:

当您的 API 应用调用*外部 API*时，这个过程被称为“回调”。因为外部开发者编写的软件会先向您的 API 发送请求，然后您的 API 再进行*回调*，向*外部 API*发送请求（很可能也是该开发者创建的）。

此时，我们需要存档外部 API 的*信息*，比如应该有哪些*路径操作*，请求体应该是什么，应该返回什么响应等。

## 使用回调的应用 { #an-app-with-callbacks }

示例如下。

假设要开发一个创建发票的应用。

发票包括 `id`、`title`（可选）、`customer`、`total` 等属性。

API 的用户（外部开发者）要在您的 API 内使用 POST 请求创建一条发票记录。

（假设）您的 API 将：

* 把发票发送至外部开发者的消费者
* 归集现金
