Is it anyone else’s experience that lately (Nov. 2011) the production URL for validating In App Purchase receipts now works to validate sandbox-generated receipts?
If this can be relied upon its a huge boon for me. It means that the build I submit to Apple can be exactly the same as the build I test with (except for final code signing.)
I’m referring to https://buy.itunes.apple.com/verifyReceipt and https://sandbox.itunes.apple.com/verifyReceipt.
I noticed this too, and it is May 2012 so I guess this has been working for awhile.
