Trello

Boards, lists and cards to help you organize and prioritize your projects

Trello's REST API gives programmatic access to boards, lists, cards, members, labels, and checklists. You can create cards, move them between lists, add comments, manage due dates, and query board activity. Authentication uses an API key + token pair, which is simpler than full OAuth for personal use. For OpenClaw agents, Trello is a natural fit for task management automation. Your agent can create cards from chat commands, move tasks through workflows, check what's overdue, or give you a daily standup summary of your board state — all triggered by cron jobs or direct messages.

Use Cases

  • Create Trello cards from Telegram messages (e.g., 'add task: review PR')
  • Generate daily standup summaries of cards due today across all boards
  • Automatically move cards to 'Done' when certain conditions are met via cron

Tips

  • Append .json to any Trello board URL in your browser to discover board/list IDs
  • Use the 'fields' parameter to limit response data and speed up requests
  • Set up a 'daily review' cron job that checks for overdue cards and alerts you

Known Issues & Gotchas

  • Rate limits are per-key AND per-token — both count independently
  • Webhooks require a publicly accessible callback URL, which complicates self-hosted setups
  • Board/list/card IDs are not obvious from the UI — use the .json trick (append .json to any Trello URL)

Frequently Asked Questions

Do I need full OAuth to use Trello API for personal automation?

No. For personal use, you can generate an API key and token directly from the Trello developer portal. Full OAuth is only needed for multi-user apps.

Can my OpenClaw agent read and write to Trello boards?

Yes. With a token that has read/write permissions, your agent can create cards, update them, move them between lists, add comments, and manage checklists.

Is Trello API free?

API access is included in all Trello plans including free. The free plan limits you to 10 boards but API functionality is the same.
