We have a crowd funding site which accepts payments via a payment gateway. We are also building an ios app for the same service.
The mobile app has a sign up button, by which users can create accounts. Once logged in, the user (investor) can fund a project/campaign they are interested in. We hope to integrate this using a mobile payment gateway or redirect to the web site's payment gateway via webview or use Apple Pay.
My question is: >>
1. Will we have to pay a 30% commission to Apple for each investment, made by an investor through the crowd funding app?
2. I understand Indiegogo, a popular crowd funding service with an ios app uses Apple Pay. Could our crowd funding app use Apple Pay as a payment gateway for our crowdfunding iOS app?
