Automate Ticket Sentiment Routing to Slack with n8n Workflow

Transform Your Customer Support with AI-Powered Sentiment Analysis and Automated Slack Routing

Eliminate manual ticket triage and ensure urgent customer issues reach the right team instantly. This intelligent n8n workflow automatically analyzes incoming support tickets for sentiment intensity using OpenAI GPT-4o, then routes them to appropriate Slack channels based on anger levels—turning hours of manual classification into seconds of automated precision.

What This Workflow Does

Your automated sentiment routing system works through six seamless steps:

• Webhook Reception: Accepts POST requests containing ticket details (ID, customer name, email, subject, message)
• Data Normalization: Sanitizes incoming data and applies safe defaults for missing fields
• AI Sentiment Analysis: OpenAI GPT-4o evaluates anger intensity on a 0-10 scale, plus sentiment category, key issues, and urgency level
• Intelligent Routing: Switch node automatically directs tickets based on anger scores—8+ goes to #escalation, 4-7 to #support, 3 and below to #feedback
• Slack Notification: Sends formatted alerts with full ticket context to the designated channel
• Response Confirmation: Returns routing results with ticket ID, sentiment score, and assigned channel

• E-commerce Operations: Fast-track angry customers with order problems to experienced agents
• Technical Support Teams: Route high-emotion bug reports directly to senior developers
