Description
We need to automate the process of syncing project tasks from our GitHub repository to a Trello board to streamline project management and tracking efforts. The goal is to automatically create Trello cards for new GitHub issues and keep them updated as issues change.

Benefits:

• Keep project updates visible in Trello for all stakeholders.
• Reduce manual overhead of copying tasks between systems.
• Enable richer cross-platform workflows with n8n.

How to Set Up with n8n Automations

1. Prepare Accounts

• Ensure you have admin access to the relevant GitHub repo and Trello board.
• Generate Personal Access Token for GitHub and get API key/token for Trello.

2. Build the n8n Workflow

• Launch n8n (self-hosted or cloud).
• Click “Create New Workflow”.

3. Add GitHub Trigger Node

• Drag in the GitHub node.
• Use the “Webhook” trigger to listen for new issues or changes.
• Authenticate with your GitHub token.

4. Add Trello Node

• Add the Trello node after the trigger.
• Use “Create Card” to make Trello cards for new GitHub issues.
• Map GitHub issue fields (title, description, labels) onto Trello card fields (card name, card description, labels).
• Authenticate with your Trello token.

5. Optional – Additional Syncs

• Add nodes for syncing comments or status changes (e.g., mark Trello card as done when GitHub issue closes).
• Add notifications, error handling, or filters as needed.

6. Test & Deploy

• Save and activate the workflow.
• Create a mock issue in GitHub to verify that it appears in Trello.

Monitor with n8n logs for troubleshooting.

Why Syncing GitHub Project to Trello via n8n Is Needed

• Integrating GitHub with Trello via n8n creates a seamless workflow that boosts productivity, reduces friction between teams, and ensures nothing falls through the cracks
• Unlike Trello boards, GitHub Projects do not support rich embeddings or interactive content within their project views. Trello allows embedding files, links, previews, and integrations directly into cards and boards, making it easier to add context or resources related to a task.
• By syncing GitHub issues to Trello via n8n, your team can take advantage of Trello’s robust embedding capabilities—such as attaching documents, visual assets, or deep links—right on project tasks. This unlocks more collaborative and context-rich project management workflows that GitHub Projects alone cannot provide

The issue provides n8n workflow steps and external GitHub/Trello references, but names no repository files, entry points, or tests. First clarify where the integration should live and how authentication and synchronization are expected to work. Done would require validating that a mock GitHub issue creates and updates the corresponding Trello card.
