How do I trigger when a ClickUp comment is posted?

Short answer: Drop the "ClickUp → Comment Posted" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in ClickUp, not on a polling schedule.

for the curious

You don’t need to read this. Tiny Command auto-maps every field into the visual picker so downstream nodes can pull values by clicking. We show it here for power users who want to know what’s on the wire.

FAQ

Questions about Comment Posted.

How does the Comment Posted trigger work in ClickUp?
Fires when a new comment is posted on a task in the selected ClickUp workspace. The webhook is registered automatically when the workflow is published. Use to mirror discussion to Slack or feed AI summaries.
Is the Comment Posted trigger real-time?
Yes. Comment Posted uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in ClickUp.
What data does Comment Posted return?
The full event payload from ClickUp. 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 Posted 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 ClickUp admin permissions to use Comment Posted?
For most ClickUp accounts a standard user can authorize the trigger. Some ClickUp plans require an admin to enable third-party webhooks. Check ClickUp's docs if the trigger fails to register.
