四年前(2014年)實作過應用內購買 (In App Purchase)，經歷讓人三溫暖的刺激感，終於跟偉大的後台工程師JK，攜手合作打造出給幼兒使用的iOS App，那可是要在美國運行的呢！

如今要再次研究Apple金流部分，IAP 驗證發票 (IAP Verify Receipt)是個必經程序，那我可以怎麼驗證購買真實性？

在IAP交易成功後記錄發票資料(Receipt Data)：

receipt-data: The base64 encoded receipt data.

未來就是要拿receipt-data去反查發票詳細內容！

我實際使用Postman測試Sandbox環境的receipt-data，真的能成功取回呢！

現在要請後台工程師來實現，每一天去反查發票，來知道用戶訂閱(Subscription)期限為何！
