The Trello Notification Gap
Trello has a native Slack Power-Up. It has been available for years, it is well-maintained by Atlassian, and it handles the common use cases — new card notifications, card move alerts, due date reminders posted to a Slack channel. For teams running entirely on Slack, this is sufficient.
But Trello has no native Microsoft Teams integration.
The Trello Power-Up marketplace lists Slack, HubSpot, Salesforce, and various other integrations. Teams is not among them. This matters because enterprise organizations increasingly run mixed messaging environments — product and design teams often on Slack, business stakeholders and leadership often on Teams, especially in Microsoft 365 shops.
When a design deliverable card moves to Done in Trello, the project sponsor who approved the budget needs to know. When a card with a red label (blocker) gets created, the account executive tracking the engagement needs to see it. If those people are in Teams, Trello's native notifications do not reach them.
What Butler Can Do (and Cannot Do Alone)
Trello's automation engine is called Butler. Butler is powerful — it can fire webhooks based on card events: card created, card moved to a specific list, due date approaching, checklist completed, member assigned, and more.
Butler's webhook action POSTs a JSON payload to any URL you specify. This is the hook that makes SyncRivo work.
The limitation: Butler sends to one webhook URL per automation rule. If you configure that URL to be a Slack webhook, Teams gets nothing. If you configure it to be a Teams webhook, Slack gets nothing. There is no native fan-out.
Routing Trello to Teams with SyncRivo
Configure Butler's webhook action to point to SyncRivo instead. SyncRivo receives the Trello event payload and routes it to all connected platforms simultaneously.
Setup (10 minutes):
- In SyncRivo, connect your Slack workspace and Microsoft Teams tenant via OAuth.
- Create a Webhook source in SyncRivo. Copy the endpoint URL.
- In Trello, open your board → Automation → Butler. Create a rule based on the trigger you want (e.g., "When a card is moved to list Done"). Add a "Send a webhook with card details" action. Paste your SyncRivo endpoint URL.
- In SyncRivo, configure routing: card moved to Done → Slack #project-team + Teams #stakeholders simultaneously; card created with red label → Slack #eng + Teams #account-team; due date reminder → Slack DM to assignee.
Routing Logic for Common Use Cases
Card moved to Done (milestone completion): The team that did the work is in Slack. The stakeholders who approved the project are in Teams. Both need to see completion. A single Butler rule → SyncRivo → both platforms simultaneously covers this without any duplication.
New card with specific label (bug, blocker): Engineers monitoring the backlog are in Slack. Product managers reviewing priorities may be in Teams. Route the blocker notification to both.
Due date approaching (48 hours): Assignees are typically in Slack. Project managers monitoring overall schedule may be in Teams. Route the reminder to Slack for the assignee and Teams for the PM channel.
Card moved to Review: Triggers a notification to the reviewer in Slack — the designer or engineer responsible for review — without any Trello polling or @mention required.
The key insight: Trello Butler is already a powerful automation layer. SyncRivo extends its reach from one platform to five (Slack, Teams, Webex, Google Chat, Zoom) without requiring additional Butler rules per destination. The routing differentiation happens in SyncRivo, not in Trello.
