Automate Slack Support Tickets with n8n & ChatGPT Integration

What this workflow does

This workflow watches a Slack channel for messages with the ticket emoji.

It stops creating duplicate tickets by checking message IDs.

Using AI (ChatGPT), it makes a short title, description, priority, and suggestions for each ticket.

Then it creates a new support ticket in Linear.

It checks Slack every minute to handle tickets fast without needing people to run it.

This saves time and helps teams avoid missing or repeating tickets.

Who should use this workflow

This is for support teams who get many Slack messages needing ticketing.

Teams that spend too much time manually making tickets in Linear will benefit.

It suits users with Slack channels dedicated to tickets.

Users comfortable with basic n8n import and configuration will find this helpful.

Tools and services used

• Slack API: To search ticket messages in a specific Slack channel.
