Zalo Medical Consultation & Appointment Booking Bot

A dental and cosmetic clinic experienced high abandonment rates on customer inquiries outside clinic working hours (6 PM - 8 AM), resulting in lost consultations and high front-desk phone congestion during peak mornings.

Built an intelligent Zalo Official Account chatbot with natural language understanding to answer common treatment FAQs, verify doctor availability in real-time, and confirm bookings directly into clinic schedules.

Conversational AI Developer: Configured Zalo OA webhooks, authored prompt safety guardrails, built intent classification nodes, and integrated booking calendar APIs.

Designed an n8n webhook listener that processes incoming Zalo messages, uses an LLM with strict clinic knowledge grounding for FAQs, and transitions seamlessly to structured booking workflows.
