How do I trigger when a Linear comment is added?
Short answer: Drop the "Linear → Comment Created" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in Linear, not on a polling schedule.

FAQ
Questions about Comment Created.
How does the Comment Created trigger work in Linear?
Fires when a comment is added to a Linear issue. Use to mirror engineering discussion to Slack or to feed AI summaries into a status doc.
Is the Comment Created trigger real-time?
Yes. Comment Created uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Linear.
What data does Comment Created return?
The full event payload from Linear. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.
Can I filter Comment Created so only some events start a workflow?
Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.
Do I need Linear admin permissions to use Comment Created?
For most Linear accounts a standard user can authorize the trigger. Some Linear plans require an admin to enable third-party webhooks. Check Linear's docs if the trigger fails to register.
