I'd like to integrate payment for subscription to our services. Currently the website offers manually-renewable subscription for 6 or 12 months, and we take the payment by Credit Card (authorize.net payment gateway) or PayPal. As we'd like to offer the users to be able to renew subscriptions from our iOS app, too, I was thinking if I could integrate the Paypal and Authorize.net SDKs in our app instead of using in-app purchases.
Here are the points related to my question from the App Store Review Guidelines:
11.2. Apps utilizing a system other than the In-App Purchase API (IAP) to purchase content, functionality, or services in an App will be rejected
11.12. Apps offering subscriptions must do so using IAP, Apple will share the same 70/30 revenue split with developers for these purchases, as set forth in the Program License Agreement.
11.13. Apps that link to external mechanisms for purchases or subscriptions to be used in the App, such as a "buy" button that goes to a web site to purchase a digital book, will be rejected.
The above points don't exactly answer my following question:
If I must use in-app purchases for subscription renewals, can I also provide users the options to pay via Paypal and Credit Card through my iOS app besides in-app purchases? Note that the "buy" button won't go to a website to purchase the subscription - I'll be integrating PayPal and Authorize.net SDKs to receive purchases from the app.
