How do I add a checklist to a Trello card?

Short answer: You can create checklist in Trello by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Trello Create Checklist action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Create Checklist.

What does the Create Checklist action do in Trello?

Adds a checklist to a Trello card with a name. Items are added separately via Add Checklist Item.

What inputs does Create Checklist require?

Required: Card ID, Checklist 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 run history shows the failed step with its input and the error message Trello returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Create Checklist support batch operations?

Run Create Checklist inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Trello's rate limits.
