Here are two diagrams, Figure 1 is a record of the IAP purchase information on itunes for a particular test, and Figure 2 is the validation information for the Apple feedback received in the background of the pen record
I have repeatedly compared these two messages and found that we could not find a common ID number. In other words, if my user only provided such a paid screenshot, I wouldn't be able to match the user's recharge to my background-recorded Apple order one by one. For example, there is billing and order number information in the top right of the itunes purchase record screenshot, but these two values do not match any of the information in the paid receipts returned by the background intercepted store kit.
This led to a situation where the user provided a Photoshop picture, or the user gave an account a punch value, and then told me another account B point to recharge the money but did not get the original package, and give me a screenshot of account A, I can not make effective distinction
Special to help you guys, I hope you can give some advice
