WhatsApp Business API Auto-Reply Enhancement

Whatsapp in app payment No redirection Reference i have I've set up an auto-reply feature for my WhatsApp Business account, and I need some enhancements. Specifically, whenever a user selects '100' from a list, a payment link for 100rs via Razorpay should be sent. Key Requirements: - Modification of current auto-reply setup to include sending payment links. - Payment links should be sent in-app, via WhatsApp, whenever '100' is selected from the list by a user. - The auto-reply message includes text and an image, so the freelancer needs to be able to integrate this with the multimedia element of the reply. - Experience with Razorpay is a plus, but not necessary. The WhatsApp Business API is already configured, so this project will focus on enhancing the existing auto-reply functionality.
