Connect Trello to Slack — No Code Required
Automate the handoff between Trello and Slack 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 Trello to Slack
Task updates in Trello affect the whole team, but most people don't check their project tool every hour. Connecting to Slack delivers those updates where people already are — in their chat tool — the moment a task is completed, assigned, or moved to a new status.
CRM deals, new orders, and code events post to Slack the instant they happen — no one needs to relay them
High-priority alerts reach the right channel or person before anyone even knows to check
Daily digests and summaries post automatically — no manual compilation, no formatting time
What you can automate between Trello and Slack
When a new card arrives in Trello, automatically post a message to a channel in Slack — no manual work, no delay
Route specific Trello cards from key sources and send a direct message in Slack the moment they arrive
Build a scheduled digest: collect Trello activity over time and post a formatted alert with details in Slack on a daily or weekly schedule
When a high-priority card is detected in Trello, notify a specific person instantly in Slack with all the relevant context included
Filter Trello cards by keyword, sender, or category — then post a message to a channel in Slack only for the ones that matter
Create a two-way feedback loop: every qualifying card in Trello triggers a record in Slack that your team can track and act on
What you stop doing manually
Trello is valuable — but without automation, it creates repetitive manual work. Here is what teams eliminate the moment they connect Trello to Slack:
Creating Trello cards by hand every time a new lead, support request, or task arrives from another tool
Manually moving cards between lists when the status changes in an external tool like a CRM or email
Copying information from emails, forms, and CRMs into Trello card descriptions one at a time
How to set it up in 3 steps
Connect Trello and Slack
Go to the Integrations tab in Vendarwon Flow and authorise both Trello and Slack. 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 card created in Trello, automatically post a message to a channel in Slack 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 card in Trello automatically triggers the right action in Slack — 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 card created in Trello, automatically post a message to a channel in Slack 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 Trello and Slack
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
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
Frequently asked questions
Does Trello have a native Slack integration?
Trello and Slack 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 Trello events can trigger the automation?
With Vendarwon Flow you can trigger automation from any of these Trello events: New card created; card moved to another list; card due date reached. You can also combine triggers — for example, only fire the automation when a card matches a specific keyword or comes from a particular source.
What can the automation do inside Slack?
Once triggered, the workflow can perform any of these actions in Slack: Post a message to a channel; send a direct message; post a formatted alert with details; notify a specific person instantly. You can chain multiple actions together — for example, post a message to a channel and then send a direct message.
How quickly does the automation run after something happens in Trello?
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 card meets your conditions in Trello, the workflow fires and the action in Slack happens instantly, whether it is 2 PM or 2 AM.
Which Slack channel or person receives the automated message?
You choose. When you describe your automation, you specify the exact channel name or person — for example "post to #sales-alerts" or "send a direct message to @john." You can also set up routing logic: send to different channels based on the content or priority of the triggering card.
