你的 API 的使用者（外部開發者）會透過一個 POST 請求在你的 API 中建立一張發票。

然後你的 API 會（讓我們想像）：

* 將發票寄給該外部開發者的某位客戶。
* 代收款項。
* 再把通知回傳給 API 使用者（外部開發者）。
    * 這會透過從「你的 API」向該外部開發者提供的「外部 API」送出 POST 請求完成（這就是「回呼」）。

## 一般的 **FastAPI** 應用 { #the-normal-fastapi-app }

先看看在加入回呼之前，一個一般的 API 應用會長什麼樣子。

它會有一個接收 `Invoice` body 的「路徑操作」，以及一個查詢參數 `callback_url`，其中包含用於回呼的 URL。

這部分很正常，多數程式碼你應該已經很熟悉了：

			}
			x = x<<8 | uint64(c)
		}
		if (x >> 63) > 0 {
			p.err = ErrHeader // Integer overflow
			return 0
		}
		if inv == 0xff {
			return ^int64(x)
		}
		return int64(x)
	}

	// Normal case is base-8 (octal) format.
	return p.parseOctal(b)
}

// formatNumeric encodes x into b using base-8 (octal) encoding if possible.
// Otherwise it will attempt to use base-256 (binary) encoding.
