Automate Customer Support with Mintlify Documentation & Zendesk AI Agent

This n8n workflow automates support ticket handling with AI-driven classification, response generation, and safety checks. Responses are based solely on your Mintlify documentation, ensuring accuracy, consistency, and reduced manual effort in customer support.

✅ Trigger: New Ticket Received The workflow is triggered whenever a new support ticket is created.

🔍 Check for Assignee If the ticket is already assigned to a human agent, the bot does nothing and exits. If the ticket is unassigned, the bot continues processing.

🔢 Bot Response Count Check The workflow checks how many times the bot has already responded to this ticket. If the bot has replied more than 3 times, it stops and waits for a human to take over. This prevents endless loops and flags potentially complex cases for review.

🧠 AI-Based Ticket Categorization An AI model analyzes the ticket content and classifies it into one of the following categories: 🧾 Billing → Sends a predefined billing-related message. 📢 Advertising → Automatically deletes the ticket. 🚨 Fraud → Sends a predefined fraud-related message. ❓ Other → Proceeds to generate a dynamic response.

🤖 Mintlify Integration For tickets categorized as "Other", the customer’s question is sent to the Mintlify API, which returns a documentation-based answer.

✍️ AI Response Formatter The raw response from Mintlify is passed to an AI model that: Summarizes and rewrites the answer in a clear, friendly tone Limits the response to 120 words Adds conversational elements like “Hi,” “Thanks,” and a proper closing

🛡️ AI Confidence Filter A second AI model reviews the formatted response to ensure it sounds confident and accurate. It looks for uncertainty phrases like: “I’m not sure” “I don’t have enough information” “It depends…” If the response is flagged as uncertain, the workflow stops and waits for a human agent to respond.

📤 Send Response & Update Ticket If the response passes the confidence check: The reply is sent to the customer The ticket status is updated to “Pending”
