其 JSON body 大致包含：

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

而它會預期該「外部 API」回傳的 JSON body 例如：

```JSON
{
    "ok": true
}
```

/// tip

注意回呼所用的 URL，包含了在查詢參數 `callback_url` 中收到的 URL（`https://www.external.org/events`），以及來自 JSON body 內的發票 `id`（`2expen51ve`）。

### 加入回呼 router { #add-the-callback-router }
