Voyons tout cela avec un exemple.

Imaginez que vous développiez une application qui permet de créer des factures.

Ces factures auront un `id`, un `title` (facultatif), un `customer` et un `total`.

L’utilisateur de votre API (une personne développeuse externe) créera une facture dans votre API avec une requête POST.

Ensuite votre API va (imaginons) :

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
* 把通知发送至 API 的用户（外部开发者）
    * 通过（从您的 API）发送 POST 请求至外部 API（即**回调**）来完成
