I want to turn my WhatsApp Business number into a first-line support channel that answers customers instantly. The goal is simple: when someone writes in with a product-related question or a basic troubleshooting issue, the system should recognise the intent and fire back the correct answer—no human intervention needed unless the chat gets escalated. Here is what I need built: • Connection to the official WhatsApp Business API (I already have the number and Facebook Business verification in place, or you can guide me through the setup if anything is missing). • A small knowledge base of product-related FAQs plus the most common troubleshooting steps, mapped to intents or keywords. • Logic that listens for incoming messages via webhook, matches them to those FAQs or troubleshooting flows, and replies automatically. • A straightforward way for me to update or add new questions without touching code—CSV import, simple admin panel, or even a Google Sheet sync works. • Clear hand-off rules: if the question falls outside the knowledge base or a customer types “agent,” the chat should be routed to my live team. • Basic analytics (message counts, resolved vs. escalated) so I can see how the automation performs. • Deployment on my preferred stack (feel free to recommend Node.js, Python, or another language you’re comfortable with) and a short hand-over guide so I can maintain it. Once everything is live, a quick walkthrough video or call showing how to add new FAQs will be enough for acceptance. If you have previous WhatsApp automation or chatbot examples, please share them in your proposal.
