FAQ

Questions about Update Comment.

What does the Update Comment action do in Todoist?

Updates the content of an existing Todoist comment. Use this to keep an automation-posted status comment current rather than spamming new ones.

What inputs does Update Comment require?

Required: Comment ID, Content. 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 Update Comment support batch operations?

Yes. Run Update Comment inside a Loop node to process arrays. Tiny Command handles Todoist's rate limits automatically so you don't have to throttle manually.
