Integration Architecture

The n8n Trello integration works through a simple yet powerful process:

1. Authentication: Securely connect your Trello account using API credentials
2. Trigger Setup: Define events that initiate workflows (new cards, comments, status changes)
3. Action Configuration: Specify what happens when triggers fire
4. Cross-Platform Integration: Connect Trello with other apps like Slack, Gmail, or HubSpot
5. Execution Logic: Add conditional logic, transformations, and filters as needed

The integration supports all core Trello functionalities including boards, cards, lists, members, checklists, and attachments. You can trigger workflows from Trello events or use Trello actions as part of larger workflow automations.
