Razorpay Integration for In-App WhatsApp Payments

REQUEST_SUMMARY_V2 Problem - Current System: Currently, payments through WhatsApp require customers to leave the chat and complete the transaction through other means, leading to potential drop-offs. Suggested Feature: Integrate with Razorpay to enable in-app payments directly within WhatsApp chats. This will allow businesses and customers to complete the entire sales process, from product discovery to payment, without leaving the WhatsApp platform. This feature aims to reduce drop-offs, offer a frictionless checkout experience, and enhance customer engagement. Expected behavior - Expose clear integration setup and mapping flow - Support reliable sync with retries and visible failure states - Allow users to verify successful data movement end-to-end Business impact - Reduces manual operational effort for teams - Improves consistency and customer experience - Helps teams move faster with fewer support escalations Legacy category: New Feature
