Finding "original_application_version" on iOS Receipt


I’ve been struggling to find the “original_application_version” in the iOS App receipt.

Our game was initially a premium purchase and we are now converting over to a free App with a “premium” IAP using Unity IAP system. As a result we need to check if the original_application_version was version 1.0 so we can unlock the appropriate content.

Any help would be greatly appreciated as I am unable to find any documentation regarding this issue.


I’m interested in this too. Did you find a solution to retrieve the receipt even though no new IAP has been made? Otherwise I’ll be writing an iOS → Unity plugin to solve this, but it would be nicer if it was possible to solve it using the normal Unity api’s.

I believe this guy found the answer for what you need:
