Unified WhatsApp Admin Chat Dashboard

I need a straightforward web-based dashboard that lets my team reply to customer WhatsApp messages from a single place. The interface should pull every incoming chat into one queue where we can: • View each customer’s message thread in real time • Reply directly from the dashboard using our connected WhatsApp number • See the sender’s WhatsApp phone number and profile name so we immediately know who we’re talking to I am not looking for advanced routing, auto-responders, or deep CRM features right now—just a clean, secure panel focused on viewing and replying. A lightweight user-login system is fine so only authorized staff can access the dashboard. You may use the official WhatsApp Business Cloud API, an on-premise gateway such as yowsup or Chat-API, or another proven solution, so long as it complies with WhatsApp’s terms and reliably delivers/receives messages. Please outline your preferred stack, estimated setup steps, and any hosting requirements in your proposal. Deliverables: 1. Source code and brief setup guide 2. Deployed demo (or screen-share walk-through) showing messages sent/received in the dashboard 3. Basic instructions for adding additional WhatsApp numbers later If you have built similar WhatsApp reply tools before, sharing a link or screenshot will help me decide quickly.
