I need an implementation that listens to incoming WhatsApp messages through the official Cloud API (or another compliant WhatsApp Business API) and immediately surfaces each message on a lightweight web-based dashboard. My scope is strictly receive-only: sending, automations, filtering, or categorisation are not required at this stage. What matters most is seeing the raw message content, sender name/number, and timestamp appear in real time (ideally via WebSocket or short-polling) on a clean, responsive interface I can open in any browser. A simple table or card layout is fine as long as new messages push to the top and unread messages stand out visually. Deliverables • API webhook endpoint that securely receives WhatsApp message events • Minimal persistence layer (in-memory or simple database) so the dashboard can refresh/history can survive page reloads • Front-end dashboard displaying each message with sender and time, auto-updating without a manual refresh • Brief setup guide covering API credentials, environment variables, and how to redeploy I prefer common stacks—Node.js/Express, Python/Flask, or PHP/Laravel are all acceptable—so choose whichever lets you deliver quickly and cleanly. Keep external dependencies minimal and open-source.
