In order to distribute an app with IAPs, the billing method has to be integrated with us, which is the One Step Payment (OSP) method. This billing integration guarantees a smoother experience both for you and your app's users.

It allows your users to be able to update your app and acquire any IAPs under the Catappult fees, being beneficial for you since you'll get the best revenue share in the market, compared to other distribution channels and stores such as Google Play. It will also provide quick updates to your apps.
