Trello automation for boards that keep moving.
Trello is where a lot of small teams run their week. Cronable creates cards from emails and forms, moves and archives them as work finishes, and starts a workflow the moment a card changes on the board you choose.
A Trello workflow on the canvas
Each card is one job. A wire means the next job runs when the one before it succeeds, or when it fails.

Every Trello step Cronable ships
Actions
Steps a workflow can take in Trello.List boards, lists and cards
Read your boards, a board’s lists, or the cards on a list or a whole board.
Get a card

Rename it, change the description or due date, move it to another list, or archive it.

Triggers
What starts a Trello workflow.Board, list or card changes
Pick a board, list or card to watch and Cronable registers the webhook. Every action on it, such as a card moved, a comment added or a list created, starts a run with the event attached.
Trello workflows worth automating first
Done cards announced
The Trello trigger fires on every change to a board, a Filter step keeps cards moved to Done, and Slack tells the team.
Requests become cards
Each Typeform response or support email creates a card on your intake list, with the details in the description.
Overdue card nudges
List a board’s cards each morning, let a Code step keep the ones past due, and comment on each to bring them back to the top.
Weekly board tidy-up
Every Friday, archive cards that have sat in Done for a week, so Monday starts clean.
How you connect
Connecting Trello
Trello connects with an API key and a user token, both pasted. Neither ever goes in a URL.
- 1Get your API key and generate a user token from Trello’s Power-Up admin page.
- 2Store them together as a username-and-password credential: the key as the username, the token as the password.
- 3For the trigger, choose what to watch and Cronable registers the webhook through Cronable’s relay, from the Basic plan up.
Your Trello automation, on your own machine
Runs on your own machine
Install Cronable as a Mac or Windows app, or on a server you own. Your Trello jobs, secrets and run history stay on that machine by default.
Built from one sentence
Describe the workflow in plain English and the built-in assistant builds the jobs, the schedule and the failure handling for you to review on the canvas. On every plan, including Free.
Unlimited runs
Plans count the jobs you define, not how often they fire. A job that touches Trello every hour costs the same as one that runs once a month.
Credentials encrypted locally
Keys and tokens are AES-256-GCM encrypted in a local database, referenced from jobs by name and masked out of logs and run output.
Trello automation, answered
Can Cronable create and move Trello cards?
Yes. It creates cards, updates, moves and archives them, adds comments, creates lists and reads boards, lists and cards.
How does Cronable authenticate with Trello?
With your Trello API key and a user token, stored together as one credential. Both are sent in the Authorization header, never in the URL, and masked in logs.
Can a Trello change trigger a workflow?
Yes. Choose a board, list or card and the Trello trigger registers a webhook on it, starting a run for every action. Inbound webhooks are included from the Basic plan.
Are Trello webhook events verified?
Auto-registered hooks are protected by an unguessable per-hook URL token. If you need every event signature-checked, wire the webhook by hand and give the trigger the signing secret and callback URL.
Where are my Trello keys stored?
Encrypted on the machine running Cronable. Jobs refer to the credential by name, so neither value appears in a job file.
