How do I get Apple to market my app with in-app purchases?

Question

Apple Developer Program

Here they have this item:
"Apps using IAP to purchase physical goods or goods and services used outside of the App will be rejected"
I have a platform within which e-book purchases are made. Books are downloaded from our server, through the Apple payment system.
It turns out that everything will be fine for me if the purchase is loaded directly into the application itself?

Answer 1

It seems to be the same with shopping. Look at the narr8 project for example. Another question is that Apple can check what exactly is being bought and require proof of rights to the content. Or, in the case of books, offer to sell them through iBooks.
