AI Hospital Chatbot n8n Workflow: Mistral + Supabase Webhook

Turn patient chat into working appointments—using an n8n AI Hospital Chatbot workflow with Mistral + Supabase

This n8n automation exposes a /ai-chat webhook that lets users chat with an AI “hospital receptionist” powered by Mistral Cloud. The workflow can answer medical questions by searching your Supabase knowledge base, and it can also register patients, list doctors, and manage appointments in your database.

What this workflow does

• Receives chat messages via webhook: It handles a POST request to the workflow’s Webhook endpoint containing the user’s chat text.
• Uses a Mistral Cloud AI Agent with memory: The user message is sent to a Mistral Cloud AI Agent, using buffer memory to maintain conversation context.
• Registers and lists patients: When users ask to register or list patients, the agent creates or retrieves patient records in Supabase.
• Lists doctors: When users ask for doctors, the agent queries Supabase and retrieves all records from the doctors table.
• Books, views, and cancels appointments: For booking and viewing, the workflow creates or retrieves appointment records in Supabase; for cancellations, it updates an appointment status to Cancelled.
• Answers medical questions with retrieval: For medical questions, it searches the medical_knowledge table by disease title and replies using the returned content.
• Returns plain-text responses: The final response is sent back to the caller via the webhook response.

Use cases

• Patient intake chat for an AI-driven clinic assistant (register/list patients).
• Automated doctor directory and appointment booking with one conversational interface.
• Symptom/disease Q&A backed by a controlled Supabase knowledge base.

Technical details

• n8n nodes: Code, Webhook, Supabase, Supabase Tool, Manual Trigger, Sticky Note.
• AI model: Mistral Cloud Chat Model (via Mistral Cloud API credential).
