How this works
Streamline your team's issue tracking by automatically creating Linear issues from Slack messages, ensuring nothing falls through the cracks in busy workflows. This suits development teams or support groups relying on Slack for discussions and Linear for project management, freeing up time from manual data entry. The key step involves the Slack trigger detecting specific commands or keywords, followed by an HTTP request to Linear's GraphQL API that formats and posts the new issue with all necessary details.
Use this workflow when your team frequently discusses bugs or tasks in Slack channels and needs instant Linear tickets to maintain momentum, particularly in agile environments with Postgres for logging timestamps. Avoid it for high-volume alerts that could overwhelm your Linear board, or if you prefer direct integrations without custom triggers. Common variations include adding AI nodes for summarising message content before issue creation, or routing to different Linear projects based on Slack channel.
