Automatically add Linear comments from external webhooks

Keep all context in one place. When external tools send notifications, Notis automatically posts them as comments in Linear, eliminating scattered conversations.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Create a comment

Creates a new comment on a specified linear issue.

Why this helps

Updates arrive from many sources (form submissions, CRM events, partner systems), but Linear doesn't always know about them. Team members miss important context and conversations fragment.

  • Automatically document external updates in Linear comments
  • Keep all context and discussions in one place
  • Reduce fragmented communication across tools
  • Create complete audit trail of all work-related events

Setup

Build it in a few focused steps.

  • 1Connect Linear to Notis.
  • 2Create an automation called 'Webhook Comments to Linear'.
  • 3Write your prompt: 'When a webhook arrives, add a comment to the related Linear issue with the notification details.'
  • 4Select 'Notis Webhook' as the trigger and copy the webhook URL.
  • 5Test by sending a test webhook and verify the comment appears in the correct Linear issue.

Questions about this workflow

How does Notis know which issue to comment on?

Notis intelligently identifies the related Linear issue from your webhook payload or based on patterns in your automation. You can also specify naming conventions in your prompt.

Can I format the comment in a specific way?

Yes. Describe your preferred format in the prompt: 'format comments as bullet points' or 'include timestamps.' Notis respects your formatting preferences.

What if the related issue doesn't exist?

You can configure Notis to create a new issue if one doesn't exist, or just log a message. Specify your preference in the automation prompt.
