I am developing iOS app which basically allows to purchase coupon codes from our server . This coupon code is shown in shop and then we can purchase physical goods of that .
I am really confused which payment mechanism i should choose,
In app purchase : Allows to sell only digital contents . We Cant sell physical goods .
Payment Gateway (like Stripe, PayPal etc) : Only physical goods can be purchased .
Should i go for In app purchase or payment gateway . Please help me .
