Frequently Asked Questions
How do I connect Trello to Slack? ▼
There's no native integration. To connect them, you will need a middleware tool like Make or n8n.
Is the connection between Trello and Slack secure? ▼
Yes. This integration typically uses OAuth 2.0, meaning you grant permission via a secure login window. You do not need to share your raw password, and you can revoke access at any time from your Trello security settings.
Is the sync one-way or two-way? ▼
This is typically a one-way sync: Trello → Slack. Changes in Slack do not sync back to Trello.
Will existing data in Trello sync to Slack? ▼
Usually, no. Most native integrations are "forward-looking," meaning they only sync data created or updated *after* you activate the connection. To move historical data, you will likely need to perform a one-time CSV export/import manually.
Can I sync custom fields? ▼
Native integration is limited to standard fields. For custom field mapping, use an automation tool.
Can I add approval steps before syncing? ▼
Native integrations can't do this. For workflows that need human review (e.g., "Manager must approve before creating invoice"), use Relay.app.
