Frequently Asked Questions

Why does Trello require me to grant write permissions?
Write permissions allow applications to create, modify, and delete cards, lists, and boards on your behalf. This is necessary for automation tools and integrations to function properly.
Is it safe to grant admin permissions to third-party apps?
Only grant admin permissions to trusted applications from reputable companies. Admin permissions allow apps to manage board settings, members, and organization-level features.
Can I revoke permissions later if needed?
Yes, you can revoke application permissions at any time by going to Settings > Apps in your Trello account and clicking 'Revoke Access' next to the application.
What happens if I don't grant the requested permissions?
The third-party application will have limited functionality or may not work at all. It will only be able to read your public board information without write or admin access.
How do I know which permissions an app actually needs?
Check the application's documentation or support pages to understand what features require specific permissions. Most reputable apps explain why they need certain access levels.
