mubashir-786/n8n-whatsapp-automation — reverse-engineered prompt

Build me a simple WhatsApp order automation system for a small restaurant or shop. I want customers to message on WhatsApp and be able to see a menu, place an order with item quantities, confirm or cancel it, and check the order status later. It should save customers, products, and orders in a local SQLite database, and handle the full order flow from incoming webhook message to order updates and replies.

Please include the WhatsApp webhook endpoints, basic API routes for orders and customers, and the n8n workflow for routing messages like MENU, HELP, TRACK, CONFIRM, and CANCEL. I also want real time responses, a clean way to customize message templates, and a simple admin facing way to view or manage products and orders if that already fits the project.

Make it easy to run locally with env setup for WhatsApp Business API credentials and webhook verification. If anything is missing, look up the current docs for WhatsApp Business API and n8n and wire it up in a practical way.
