I am developing an iOS app for selling physical goods and for that, I want to redirect my user to my website for checkout and payment process. I want to confirm if that is allowed by apple guidelines. I tried to check with apple support but couldn't get a satisfactory answer. I am not asking about redirecting the user to the PayPal/stripe website but my own website where I have Authorize.net integration and want my user to make payment there and then I will take him back to my app. As per my understanding, external payment is allowed for physical goods but I want to check if my use case is acceptable or not.
