For Paywall Management-only plans
This method is for customers who have implemented their own in-app purchases or subscription code directly with the App Store, Google Play, etc. or who are using another third-party for subscription or purchase management.
Your Nami account needs to be on a Paywall Management-only plan to use this interface. Contact [email protected] for details.
NamiPaywallManager.registerBuySkuHandler will provide a callback from a Nami paywall when the user has selected a sku and asked for the purchase flow to start.
It is you're responsible to listen to this handler's callback to start the purchase with the provided sku.
Once the purchase is successful, indicate it is complete by calling buySkuComplete to close the paywall.
