Connect Slack to Trello — No Code Required
Automate the handoff between Slack and Trello using plain English. Describe what you want to happen and Vendarwon Flow builds and runs the workflow automatically — forever, in real time, without developer help.
Why teams connect Slack to Trello
Requests, decisions, and action items come up constantly in Slack, but tracking them requires creating a task in Trello — which most people skip because it takes too long. Connecting the two means a simple keyword or reaction in chat can automatically create the corresponding task.
New emails, form submissions, and leads automatically create Trello cards with all the details filled in
Cards move to the right list automatically when status changes in your CRM or other tools
Trello card updates trigger Slack messages or emails automatically — no manual status sharing needed
What you can automate between Slack and Trello
When a new message arrives in Slack, automatically create a card on a board in Trello — no manual work, no delay
Route specific Slack messages from key sources and move a card to a list in Trello the moment they arrive
Build a scheduled digest: collect Slack activity over time and add a comment to a card in Trello on a daily or weekly schedule
When a high-priority message is detected in Slack, attach data to a card in Trello with all the relevant context included
Filter Slack messages by keyword, sender, or category — then create a card on a board in Trello only for the ones that matter
Create a two-way feedback loop: every qualifying message in Slack triggers a record in Trello that your team can track and act on
What you stop doing manually
Slack is valuable — but without automation, it creates repetitive manual work. Here is what teams eliminate the moment they connect Slack to Trello:
Manually typing updates into Slack every time something changes in another tool
Pasting CRM updates, new orders, or GitHub alerts into channels by hand throughout the day
Checking multiple tabs and tools then summarising status in Slack so the team knows what's happening
How to set it up in 3 steps
Connect Slack and Trello
Go to the Integrations tab in Vendarwon Flow and authorise both Slack and Trello. Each takes under 2 minutes — just click Authorise and follow the prompts. No API keys to configure manually, no webhooks to set up.
Describe your automation in plain English
Click New Workflow and type what you want to happen. For example: "When there is a new message posted in a channel in Slack, automatically create a card on a board in Trello with all the relevant details included." The AI reads your description and builds the complete workflow — triggers, actions, conditions, and all.
Activate and it runs forever
Review the workflow in the visual editor, adjust any details, then click Activate. From that moment, every qualifying message in Slack automatically triggers the right action in Trello — no manual steps, no missed triggers, no babysitting required.
Type this to get started
Copy this prompt into the Vendarwon Flow workflow builder. The AI will generate the complete workflow in seconds — you can then refine it in plain English.
Example prompt
“When there is a new message posted in a channel in Slack, automatically create a card on a board in Trello with all the relevant details included.”
You can add conditions, extra steps, and filters in plain English after the AI generates the base workflow.
About Slack and Trello
Slack
Team Messaging
Slack is the team communication hub used by over 750,000 companies worldwide. While it excels at conversation, the painful reality is that most alerts, updates, and status changes from other tools still get posted to Slack manually — by a person copy-pasting from another tab.
Available triggers
- new message posted in a channel
- keyword or mention detected
Available actions
- post a message to a channel
- send a direct message
- post a formatted alert with details
- notify a specific person instantly
Trello
Project Management
Trello is the visual project management tool with over 50 million users who rely on its simple card-based interface. The challenge every Trello team faces: boards fill up only when someone manually creates cards — so work that comes in through email, forms, or other tools often never gets tracked.
Available triggers
- new card created
- card moved to another list
- card due date reached
Available actions
- create a card on a board
- move a card to a list
- add a comment to a card
- attach data to a card
Frequently asked questions
Does Slack have a native Trello integration?
Slack and Trello do not have a built-in direct integration that covers most real automation scenarios. Vendarwon Flow acts as the bridge — you describe what you want in plain English and it handles the API connections between both tools securely. No Zapier account, no developer, no webhook configuration needed.
What Slack events can trigger the automation?
With Vendarwon Flow you can trigger automation from any of these Slack events: New message posted in a channel; keyword or mention detected. You can also combine triggers — for example, only fire the automation when a message matches a specific keyword or comes from a particular source.
What can the automation do inside Trello?
Once triggered, the workflow can perform any of these actions in Trello: Create a card on a board; move a card to a list; add a comment to a card; attach data to a card. You can chain multiple actions together — for example, create a card on a board and then move a card to a list.
How quickly does the automation run after something happens in Slack?
In real time — typically within a few seconds of the triggering event. Vendarwon Flow runs continuously in the cloud, so there is no polling delay. The moment a new message meets your conditions in Slack, the workflow fires and the action in Trello happens instantly, whether it is 2 PM or 2 AM.
Can I add conditions so only certain messages trigger the automation?
Yes — conditional logic is built in. You can describe rules like "only trigger when the message contains the word urgent" or "skip if the source is internal." Vendarwon Flow supports AND/OR conditions, keyword matching, and value comparisons, all configured in plain English without writing any code or building separate logic branches.
