Does anyone validate their receipts after an IAP purchase is made,
e.g. as an additional confirmation?
If so, is there any advice on how to do it locally?
My ‘receipt data’ returned after succesfully calling [Make In App Purchase] is an encryptyed string but the UE4 docs don’t explain what it is for or how/where to use it.
You should validate receipt on your own cloud server or using Third-Party services.
Hi,
Thanks, I am aware of the cloud-server validation method as mentioned in the apple.com link I posted.
I’m interested in how to Validate Receipts ‘Locally’.
This is the best explanation/summarization and sample code I’ve found for validating purchase receipts client side…
It’s a bit of work get to get OpenSSL to build from source largely from numerous configuration options/settings but we’ve implemented this into a production title and the results were a stark drop in pirated purchases that were skewing revenue reports. You will find this project helpful as well for building an OpenSSL static library for iOS…
Wow, thanks robertfsegal, that was quite a heavy-duty read!
Sure no problem.
