I built a WhatsApp AI

I built a WhatsApp AI Assistant using n8n and the Meta Business API to automate customer communication, appointment booking, and follow-ups directly inside WhatsApp.

The assistant is designed to handle natural conversations with users, answer questions, manage bookings through Phorest, and send automated appointment reminders — all through a fully automated workflow.

One of the key challenges was that Meta does not provide persistent chat history storage. To solve this, I built a custom chat history system with a WhatsApp-style interface that recreates the native messaging experience while keeping all conversation data fully controlled and accessible.

The system combines AI-driven conversations with workflow automation to create a smooth customer support and booking experience.

Features: • AI-powered WhatsApp conversations • Appointment booking integration with Phorest • Automated reminders and follow-ups • Custom WhatsApp-style chat history interface • Flexible workflow automation using n8n

Tech stack: • n8n • Meta WhatsApp Business API • Python • REST APIs • Phorest API • Custom chat history system

This project strengthened my experience in AI automation, messaging platform integrations, workflow orchestration, and customer communication systems.
