Native WhatsApp Commerce, Razorpay Payment & Shiprocket Integration

I’m looking for an experienced WhatsApp Cloud API developer to build a complete native WhatsApp ordering, payment, and shipping workflow for my jewellery brand Queziva. Current Setup Meta Business / WhatsApp Business Platform already set up WhatsApp Catalogue already available Meta WhatsApp Payment Configuration already created Razorpay authorization completed and payment configuration is Active Shiprocket will be used for shipping and tracking Required Workflow Customer → Cart → Place Order → Admin Review → Approve/Modify → Customer Confirmation → Address → Shiprocket Shipping Calculation → Final Order → Native WhatsApp Pay Now → Razorpay Payment → Order Confirmation → Shiprocket Shipment → Tracking → Delivered → Feedback/Unboxing → Instagram Follow-up Key Requirements Customer places order from WhatsApp Catalogue Order initially comes to Admin for review, without payment Admin can check stock and modify quantity/items Example: Customer orders 2, only 1 available → Admin changes quantity to 1 Customer must approve any modified order Collect delivery details through WhatsApp Calculate shipping charges through Shiprocket API Add shipping + applicable GST/tax/discounts Generate final payable amount Send native WhatsApp order_details + Pay Now Integrate with already-authorized Razorpay native WhatsApp payment Verify payment through webhook Generate/confirm Queziva Order ID Automatically create Shiprocket shipment after successful payment Send dispatch + AWB + tracking updates through WhatsApp Send delivered/unboxing message Send post-delivery feedback/review and Instagram follow-up Maintain complete order status/history Admin Dashboard Admin should be able to manage: New Order → Pending Review → Modified → Customer Approval → Ready for Payment → Paid → Processing → Shipped → In Transit → Delivered → Completed/Cancelled Including SKU, stock, quantity, pricing, shipping, GST, payment, Shiprocket and tracking details. Important I need native WhatsApp commerce/payment integration, not a simple WhatsApp chatbot or external Razorpay payment-link solution. Developer should have real experience with: WhatsApp Cloud API + WhatsApp Flows + order_details + Native WhatsApp Payments + Razorpay API/Webhooks + Shiprocket API/Webhooks.
