How to Connect Linear to Slack Without Code (2025 Guide)

Why connect Linear to Slack?

Linear is the issue tracker of choice for fast-moving engineering teams. Slack is where those teams communicate. Keeping everyone in sync — posting updates when issues change status, alerting the right channel when a high-priority bug is filed, notifying a PM when their feature ships — requires a connection that doesn't exist out of the box.

This guide shows you how to connect Linear to Slack in under 10 minutes without writing a single line of code.

What you will build

A live webhook that automatically posts a message to a Slack channel whenever:

Step 1: Describe what you want

Open APIlot (useapilot.com) and type your request in plain English:

"When a new Linear issue is created with priority Urgent or High, post a message to our Slack channel #engineering-alerts with the issue title, assignee, and link."

Or:

"When a Linear issue status changes to Done, post a completion message to #product-updates on Slack with the issue title and who completed it."

APIlot identifies that this requires the Linear Webhooks API and the Slack Web API.

Step 2: Review the generated code

APIlot generates:

Step 3: Configure environment variables

Linear webhook secret:

Go to Linear → Settings → API → Webhooks → Create a new webhook → Copy the signing secret.

Slack bot token:

Go to api.slack.com/apps → Create New App → Add chat:write OAuth scope → Install to workspace → Copy the Bot User OAuth Token.

Slack channel ID:

Right-click the Slack channel → View channel details → Copy channel ID (starts with C...).

Step 4: Deploy

Click the GitHub deploy button in APIlot. The code lands in a private GitHub repository. Deploy it to Railway, Render, or Fly.io to get a public URL.

Step 5: Register the webhook in Linear

In Linear → Settings → API → Webhooks:

1. Set the URL to your deployed server's endpoint

2. Select the event types you want

3. Save and test with a sample issue

That's it

Your Linear to Slack integration is live. Every qualifying event in Linear now automatically posts to your Slack channel. The whole process takes under 10 minutes — no developer, no dev ticket.

Want to modify the Slack message format? Edit slack-client.ts directly, or describe the change to APIlot and regenerate.
