  * Replicate a service definition and change the name of the new service appropriately.

API 应用调用外部 API 时的流程叫做**回调**。因为外部开发者编写的软件发送请求至您的 API，然后您的 API 要进行回调，并把请求发送至外部 API。

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*，返回什么样的请求体，应该返回哪种响应等。

## 使用回调的应用

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

## 常规 **FastAPI** 应用
