Trello to Slack Notification Trigger: Task/Card Move Alerts Workflow Solution

Workflow overview

Why this workflow matters

Improves internal consulting operations and productivity.

Sends a Slack notification whenever a Trello card is moved between lists on a specific board. Message format (bolded parts): Task: {{ $json.Task }} moved from {{ $json['Previous Step'] }} to {{ $json['New Step'] }} ⚙️ Setup Instructions 1️⃣ Connect Trello (Developer API) Get your API key here → Trello App Key On the same page, generate a Token (click Token). In AlekSystem → Credentials → New → Trello API → paste API Key + Token, then save. Open each Trello node (Get Board, Get Lists, Get Cards) and select your Trello credential. 2️⃣ Connect Slack Go to Slack API Apps and create a new app. Add OAuth & Permissions → include scopes like: chat:write (to send messages) users:read (if targeting specific users) Install the app to your workspace → copy the Bot User OAuth Token. In AlekSystem → Credentials → New → Slack OAuth2 API → paste the token and save. In your Slack node (e.g., Send a message), select your Slack credential, and choose whether to send messages to a channel or a user. 3️⃣ Get Your Trello Board ID Find your board’s shortlink in the URL (e.g. in https://trello.com/b/DCpuJbnd/administrative-tasks, the shortlink is DCpuJbnd). Run this request in an HTTP node (replace placeholders with your values): GET https://api.trello.com/1/boards/{BOARD_SHORTLINK}?fields=id&key={YOUR_TRELLO_KEY}&token={YOUR_TRELLO_TOKEN} Copy the "id" from the response — that’s your board ID. Paste it into the Trello Trigger node under Model ID. 📬 Contact Need help customizing this workflow or building automations? 📧 robert@ynteractive.com 🔗 Robert Breen 🌐 ynteractive.com
