⚡ 261 views · 📋 Project Management

⚙️ 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 n8n → 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 n8n → 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):
Copy the “id” from the response — that’s your board ID.
Paste it into the Trello Trigger node under Model ID.
