How it works

The text below comes from the sticky notes inside the workflow. We removed links, code samples and anything that looks like a key or token.

Try It Out!

This workflow does the following

  • Monitors a Slack channel for new user messages asking for assistance
  • Only user messages which are tagged with the ticket emoji are processed.
  • Linear is first checked to see if a ticket was created for the user message.
  • User messages are sent to ChatGPT to generate title, description and priority.
  • Support ticket is created in Linear.

1. Query Slack for Messages

Slack API search uses the same search syntax found in the app. Here, we'll use it to filter the latest messages with the ticket emoji within our designated channel called #n8n-tickets.

  • Set the Slack channel to monitor here.

3. Use AI to Generate Ticket Contents

For this demo, we've instructed the AI to do the following

  • Generate a descriptive title of the issue
  • Summarise the user message into an actionable request.
  • Determine a prority based on tone and context of the user message.
  • Can offer possible fixes through use of tools or RAG. (not implemented)

4. Create New Ticket in Linear

For generated issues, we add the message id to the description of the message so that we can check them at this point in the workflow to avoid duplicates.
