FAQ

Questions about Create List.

What does the Create List action do in Trello?

Creates a new list on a Trello board with name and position. Used for templated board scaffolding (Backlog, In Progress, Done).

What inputs does Create List require?

Required: Board ID, List Name. 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 Trello 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 Create List support batch operations?

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