I've been searching StackOverflow for a while now but I still couldn't find an answer to my question.
From this link :PayPal API for iOS - allowed? "Yes, as long as you are not selling digital goods, you can use the PayPal API"
How do they define digital goods? Is e-Ticketing (ticket with QRcode/BarCode) considered as digital goods?
I've came across cinemas app that are approved. (Just a little paranoid here)
