Triage support tickets by GPT-4o sentiment and route them to Slack

Analyze customer support ticket sentiment and route to Slack channels

Who is this for

Customer support teams, customer experience managers, and operations teams that need to triage incoming support tickets in real time without manual classification. Ideal for SaaS companies, e-commerce businesses, and service providers handling high ticket volumes.

What this workflow does

This workflow automatically triages incoming customer support tickets by sentiment using OpenAI GPT-4o. A ticket arrives via webhook, is normalized, analyzed for anger intensity (scored 0-10), and routed to the correct Slack channel in real time. High-anger tickets are escalated immediately, mid-range tickets go to standard support, and low-anger tickets or feedback are logged separately.

How to set up

Add your OpenAI API credential to the AI sentiment analysis node Add your Slack OAuth2 credential to all three Slack nodes Update Slack channel names (#escalation / #support / #feedback) to match your workspace Activate the workflow and copy the webhook URL for your support form integration Send a test request to verify end-to-end execution

Requirements

OpenAI API account with GPT-4o access Slack workspace with OAuth2 app installed (chat:write scope) Three Slack channels: one for escalation, one for support, one for feedback

How to customize

Adjust the anger score thresholds in the Switch node to match your team's escalation policy. Modify the GPT-4o prompt to detect additional sentiment categories or extract custom fields from tickets. Add language detection for multilingual support.
