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

What this trigger returns

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 Added.

How does the Comment Added trigger work in Todoist?

Fires whenever a comment is added to a Todoist task. Use it to mirror discussion to Slack or push transcripts into your project log.

Is the Comment Added trigger real-time?

Yes. Comment Added uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Todoist.

What data does Comment Added return?

The full event payload from Todoist. 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 Added 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 Todoist admin permissions to use Comment Added?

For most Todoist accounts a standard user can authorize the trigger. Some Todoist plans require an admin to enable third-party webhooks. Check Todoist's docs if the trigger fails to register.
