Adding Native Payments (Google/Apple IAP) to Existing PWA

Description

Project Description:
Need a developer to integrate native in-app purchase functionality (Google Play Billing and Apple In-App Purchases) into our existing Progressive Web App (PWA) that is wrapped for Android and iOS using Super PWA Pro. The solution should conditionally use these native payment systems when the app is running as a standalone mobile app (installed from the app stores) and retain the existing WooCommerce payment gateway when the PWA is accessed via a web browser. The developer will be responsible for implementing the purchase flow, handling responses, and ensuring proper communication with both the native platforms and our backend (if necessary). Thorough testing on both Android and iOS is required.
