WhatsApp Chat Admin Automation

I handle all customer enquiries through WhatsApp and now I need a small web-based admin panel that centralises every conversation in one place. From that single dashboard I must be able to read and reply to any incoming message without touching my phone.

Automation is equally important. The system has to:
• send an instant welcome message the first time a customer writes
• answer automatically outside office hours with my custom text
• recognise specific keywords and push the matching pre-set reply

I do not require sophisticated load-balancing between multiple agents right now; a single-user workspace is fine as long as the codebase leaves room for future expansion.

I prefer to stay within Meta’s official WhatsApp Business API ecosystem—Twilio, 360dialog, or the native Cloud API are all acceptable—so please choose whichever integration you know best and keep it compliant. A lightweight stack (Node, PHP, Python or similar) is perfect; just avoid vendor lock-in.

Deliverables
1. Working web dashboard accessible via modern browsers
2. Three automation flows configured and tested exactly as described
3. Deployment script or Docker file plus a brief user guide so I can host it on my own VPS

Once everything is installed and I can send, receive, and see each automated reply trigger correctly, I’ll consider the job complete.
