Choosing an integration method for IAP

IAP integration can be performed either automatically or manually. Below you can find more detail on these methods.

Automatic IAP integration

(1) Automatic SDK integration
The automatic IAP integration works with apps available on Google Play Store and does not require any effort from the developers side. Developers only need to provide the app's Google Play link and Catappult is responsible for migrating the data.

This method is available for apps without IAP as well.

Manual IAP integration

Developers can either choose between one of the two manual integration methods:

(2) Catappult IAP SDK
An alternative for developers that have already integrated Google Play billing SDK and want to integrate SDK themselves.

(3) One-step payment
Best option for developers that want to quickly support payments on their apps and have not integrated Google Play billing SDK.
