Trello Integration & Workflow Automation
Run Trello on autopilot. Keep the veto.
256 actions50 triggers
Cards get created, comments post, and checklists update before you've seen what triggered them. Rills proposes each Trello action; you approve before it goes out.
Interactive. No signup. 14 days free · approvals always free.
Most automation fires first, asks later. Rills shows you the change before it ships.
Every consequential project management action from Trello arrives on your phone first. Approve in seconds. Decline without explaining yourself. Workflows wait, paused at zero cost, until you decide.
Queue 3
Create 6 cards across 3 client boards from this week's intake?
6 intake items · submitted in last 24h
Same board mapping as last Monday's batch
2 cards target client-visible lists — confirm placement
Free to wait. Free to think.
Approvals and logic don't cost a credit. Pause a workflow for three hours or three weeks. The price is the same: zero. You only pay when something real happens: an AI call, an outbound action.
Approve from your phone in five seconds.
Swipe right when you're sure. Decline when you're not. Between meetings, mid-coffee, on the train. No dashboard to babysit, no inbox triage, no 3am stomach-drop wondering what shipped while you slept.
Routine cases graduate themselves.
Every approval feeds a confidence score for that exact workflow shape. The obvious cases (the ones you've green-lit fifty times) start running on their own. The judgment calls still come to you.
About Trello automation
Project management automation sounds safe until a card gets created in the wrong list, a comment posts to the wrong client board, or a member gets added to something they shouldn't see.
When Trello runs unsupervised
Trello events fire fast, and most automation tools respond immediately. A single misconfigured rule sends the wrong card to the wrong team before anyone notices.
- createCard on the wrong trigger: A card gets created in a client-facing list from internal intake data, and the client sees work-in-progress notes they weren't meant to.
- addMemberToCard without review: A new member gets added to a card with sensitive attachments because the automation matched on name alone.
- commentCard fires before context is ready: An automated comment posts to a card before the upstream data it references has finished updating, so the comment reads as incomplete or wrong.
- addChecklistToCard on stale data: A checklist gets added to a card that was already completed, cluttering the board and confusing whoever picks it up next.
- deleteCard without confirmation: A card deletion fires on a false-positive match, and the work record is gone before anyone catches it.
What Rills does inside Trello
Rills watches your Trello triggers, including createCard, addMemberToCard, and commentCard, and holds each proposed action in a queue instead of executing immediately. When a checklist needs updating or a new card is ready to create, Rills surfaces the proposal with the context it used to build it, so you can read the reasoning before anything hits the board.
The card still gets created; you just see what it says and where it's going first.
When Trello events should and shouldn't act on their own
Not every Trello automation trigger carries the same risk. Some are routine enough to run without a second look; others touch things you'd want to read before they go out.
- createList: Low stakes, structural change only, a good candidate to graduate to autonomous once the pattern is established.
- copyCard: Routine duplication inside a known board can run without review after a few confirmed approvals.
- addToOrganizationBoard: Adding a board to an org changes visibility and access for everyone on it; always worth a human check.
- addMemberToBoard: Membership changes are hard to reverse quietly; a proposal here keeps you in control of who sees what.
- commentCard: A comment that posts to a client-facing card under your name is yours to own; approve Trello comments before they go out, every time.
- deleteCard: No recovery path without a backup; this one should never run on its own.

Common questions about Trello automation
How do I automate Trello card creation without losing control?
Rills watches your triggers, like a new board being created or a member added to a card, and proposes the next action for you to approve before anything ships. You keep the veto on every card, checklist, or comment that goes out.
Can I get mobile approvals before a Trello card or comment goes out?
Yes. Every proposed Trello action lands in your mobile approval queue. You review it from your phone, swipe to approve or reject, and only then does Rills execute. Nothing posts to your board while you are unreachable.
How do I automate checklist updates in Trello across multiple cards?
Rills can propose checkitem updates across cards based on triggers you define, like when a member is added or an attachment lands. Each batch of updates waits for your approval before it touches your board, so a bad rule does not silently corrupt your project tracking.
Can I automate Trello card assignments when new members join a board?
When an addMemberToBoard or addMemberToCard event fires, Rills can propose the follow-on card assignments or checklist additions. You decide which proposals go through before they reach your team's view.
How do I set up Trello automation that only runs when I approve it?
Connect Trello to Rills, define which events should trigger proposed actions, and Rills queues every proposal for your review. Routine decisions can graduate to autonomous over time as confidence scoring learns your patterns, but you control when that happens.
How is Rills different from Zapier for Trello automation?
Zapier fires actions the moment a trigger hits. Rills proposes the action first and waits for your call. If a rule is wrong, Zapier has already shipped it to your board or your team's inbox. With Rills, you catch the mistake before it goes out, not after someone files a complaint.
Does Rills support Trello event triggers like card creation and comments?
Yes. Rills supports Trello events including createCard, commentCard, addChecklistToCard, addMemberToCard, addAttachmentToCard, and more. Each event can trigger a proposed action that sits in your approval queue until you confirm it.
How much does Rills cost for Trello automation?
Approvals and workflow logic are free. You only pay when Rills executes a real action, like an AI call or an external operation on your Trello board. You can review and reject as many proposals as you want without being charged anything.
