n8n AI Support Ticket Triage: GPT-4o Reply + Slack Alerts

Instant AI triage for your support inbox—GPT-4o drafts replies, escalates urgent tickets to Slack, and logs everything to Google Sheets.

If you run customer support in a fast-moving SaaS, this n8n AI support ticket triage workflow helps you respond faster and route issues correctly. It receives new tickets via webhook, uses OpenAI (GPT-4o) to determine priority and draft a response, escalates high-priority cases in Slack, then sends an email auto-reply and tracks outcomes in Google Sheets.

What this workflow does

• Receives new tickets through an HTTP POST webhook (subject + body).
• Calls OpenAI (GPT-4o) to classify the ticket, including priority, and generate a drafted reply.
• Extracts the priority from the AI output and uses it to route high-priority requests for escalation.
• Escalates urgent tickets to Slack by posting a message to your chosen channel (e.g., an on-call channel like #support-urgent).
• Sends an email auto-reply using the ticket subject and the AI-drafted response via SMTP/Email credentials.
• Appends ticket details and results to Google Sheets for tracking and reporting.

Use cases

• Support teams who want consistent ticket routing and faster first responses.
• SaaS operators needing Slack alerts for urgent issues without manual review.
• Automation engineers building a webhook-based helpdesk triage workflow in n8n with audit-friendly logging.

Technical details

• Webhook: HTTP POST intake for ticket subject and body.
• OpenAI (GPT-4o): priority classification + drafted reply generation.
• Switch + Set: priority extraction and branching.
