FAQ

Questions about Complete Task.

What does the Complete Task action do in Todoist?
Closes a Todoist task. Recurring tasks roll forward to their next due date instead of disappearing.
What inputs does Complete Task require?
Required: Task ID. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Todoist returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Complete Task support batch operations?
Yes. Run Complete Task inside a Loop node to process arrays. Tiny Command handles Todoist's rate limits automatically so you don't have to throttle manually.
