Guideline 3.1.1 - Business - Payments - In-App Purchase
We noticed that your app or its metadata enables the purchase of content, services, or functionality in the app by means other than the in-app purchase API, which is not appropriate for the App Store.
Specifically, your app enables points, or intermediate currencies, without using the in-app purchase API. Additionally, please note that the cost of the points or the intermediate currency cannot be included in the purchase price of the app.
While the payment system that you have included may conduct the transaction outside of the app, if the purchasable content, functionality, or services are intended to be used in the app, they must be purchased using in-app purchase, within the app - unless it is of the type referenced in guideline 3.1.3 of the App Store Review Guidelines.
It may be appropriate to revise your app to use the in-app purchase API to provide content purchasing functionality.
In-app purchase provides several benefits, including:
- The flexibility to support a variety of business models.
- Impacting your app ranking by consolidating your sales to one app rather than distributing them across multiple apps.
- An effective marketing vehicle to drive additional sales of new content.
