Trello

Overview

The Trello integration connects your Trello boards to Monday Morning, enabling card syncing and board-to-project mapping. This is useful for teams transitioning from Trello to Monday Morning, or for maintaining parallel views of project work across both tools.

Prerequisites

• A Trello account
• A Trello API Key and API Token from the Power-Up admin page
• Access to the boards you want to sync

Setup

Step 1: Get Your API Key

1. Go to trello.com/power-ups/admin
2. Click on New to create a Power-Up (or use an existing one)
3. Copy the API Key displayed on the page

Step 2: Generate an API Token

1. On the same Power-Up admin page, click the link to generate a Token
2. Authorize the token to access your Trello account
3. Copy the generated token

Step 3: Configure in Monday Morning

Set both credentials as environment variables in your shell profile:

export TRELLO_API_KEY="your_api_key_here"
export TRELLO_API_TOKEN="your_api_token_here"

Alternatively, configure them through the Monday Morning desktop app under Settings > Integrations > Trello. Enter your API Key and API Token in the respective fields.

Step 4: Verify the Connection

Ask your AI agent to sync a Trello board:

Sync my Trello board with this project

The agent will call the Trello sync tools. If configured correctly, you will see cards from your board reflected in Monday Morning.

Available Tools

Tool	Description
mm_sync_trello	Sync cards and boards between Trello and Monday Morning.
mm_export_trello	Export Monday Morning tasks and specs to a Trello board.
mm_import_trello	Import cards from a Trello board into Monday Morning.

Common Workflows

Import a Trello board into Monday Morning

Import all cards from my "Product Roadmap" Trello board

The agent calls mm_import_trello to pull cards from the specified board and create corresponding tasks or specs in .mm/.

Export Monday Morning tasks to Trello

Export my current tasks to the "Sprint Board" on Trello

The agent calls mm_export_trello to push tasks from .mm/ to the target Trello board.

Keep boards in sync

Sync my Trello board with this project in both directions

The agent calls mm_sync_trello to reconcile changes between Trello and Monday Morning.

Troubleshooting

“Unauthorized” error Your API key or token is invalid. Regenerate them at trello.com/power-ups/admin.

“Board not found” error Ensure you have access to the board and that the board ID or name is correct. Private boards require the token to be generated by a board member.

Cards not syncing Check that both TRELLO_API_KEY and TRELLO_API_TOKEN are set. The API key alone is not sufficient — Trello requires both for authenticated requests.

Column mapping issues Trello lists map to Monday Morning task statuses. If cards appear in unexpected columns, check the list-to-status mapping in your integration settings.
