How do I trigger when a new Trello list is created?
Short answer: Drop the "Trello → New List" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in Trello, not on a polling schedule.

FAQ
Questions about New List.
How does the New List trigger work in Trello?
Fires when a new list is created on a Trello board. Useful for templated board provisioning or governance audit logs.
Is the New List trigger real-time?
Yes. New List uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Trello.
What data does New List return?
The full event payload from Trello. 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 New List 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 Trello admin permissions to use New List?
For most Trello accounts a standard user can authorize the trigger. Some Trello plans require an admin to enable third-party webhooks. Check Trello's docs if the trigger fails to register.
