Apple have rules about whether you are required to use in-app purchases vs other payment processors in your app.
Specify that apps that let users purchase digital items(credits) require in-app purchases, whereas apps that sell you real-world goods and services are required to use a different payment processor.
In my app, I want a mix between those two concepts to allow users to pay for real-world goods with credit card or with digital coins/credits.
Essentially these credits can be received for free by accomplishing various tasks within the app, which are then used to pay for physical goods(shoes, watches etc.).
BUT users can also purchase extra credits with real money so they can buy physical goods.
Credits are only used to purchase real-world goods!
It is multiplatform project that have web and android app.
Would the purchase of these credits fall under in-app purchases or other payment systems?
