I need a WhatsApp-based chat-bot that connects to ChatGPT and takes over the entire order-processing flow for my store. The bot must automatically: • collect and validate product information • capture payment details securely • record the customer’s contact information End-to-end, the conversation should feel natural thanks to ChatGPT, yet every step must translate into structured data I can push into my existing back-office. Think of a user messaging “I want two blue hoodies”; the bot confirms stock, calculates totals, asks for payment, issues a receipt, and stores name, phone, and address—without any manual touch. Please build on the official WhatsApp Business API (Twilio, Meta Cloud API, or similar) and wire it to the ChatGPT API. A lightweight admin panel or webhook endpoint where I can see raw order objects is enough; no full CRM needed. Deliverables: 1. Source code (Node.js or Python) and README for local deployment. 2. Cloud-hosted instance running in my account. 3. Short video or live demo showing a complete order cycle. If you have prior WhatsApp automation or GPT integration samples, share a link in your proposal so I can assess fit quickly.
