Short answer: Drop the "Todoist → Task Completed" 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.

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 Task Completed.

How does the Task Completed trigger work in Todoist?

Fires when a task is marked complete in Todoist. Common use: log productivity metrics, ping the requester, or move related items forward in a downstream system.

Is the Task Completed trigger real-time?

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

What data does Task Completed 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 Task Completed 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 Task Completed?

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.
