Automatic Trello Board Cleanup by Removing Cards with Specific Labels

Automatically clean up Trello boards by deleting any cards labeled “Mark for Deletion.”

This workflow checks all cards on your chosen Trello board, looks for the Mark for Deletion label, and removes those cards automatically — keeping your boards tidy without manual effort.

⚙️ Setup Instructions

1️⃣ Connect Trello (Developer API) Get your API key: https://trello.com/app-key
Generate a token (from the same page → Token) In n8n → Credentials → New → Trello API, paste API Key and Token, save.
Open each Trello node (Get Board, Get Lists, Get Cards) and select your Trello credential.

2️⃣ Add Your Board URL to “Get Board” Copy your Trello board URL (e.g., https://trello.com/b/DCpuJbnd/administrative-tasks).
Open the Get Board node → Resource: Board, Operation: Get.
In ID, choose URL mode and paste the board URL.
The node will resolve the board and output its id → used by Get Lists / Get Cards.
