Power users: Claude to Trello
Want your own Claude (or any AI agent) to drop finished briefs straight into your board? Two steps.
1. Get your Trello keys (2 min)
Click New → create a Power-Up (any name, leave the iframe URL blank).
Open it → API Key tab → copy your API Key.
On the same page, click the “Token” link → set an expiration (30 days is plenty) → Allow → copy your Token.
Keep these private: the token gives access to your whole Trello account, not just this board. Revoke it anytime from the same page, and revoke it immediately if you ever share a chat transcript.
2. Paste this into Claude
Fill in your key, token and board name, then paste the whole thing into Claude Code (or your agent):
SETUP PROMPT — PASTE INTO CLAUDE
You can post design requests to my Yumi Trello board using the Trello API. Yumi is the design subscription I use for product, web and brand design: one request at a time, delivered in ~48h, and a brief locks once the request goes active. My Trello API key: [paste key] My Trello token: [paste token] My board is named: Yumi — [my name] Setup: use the Trello API to find my board and my “Backlog” list. Write every request in the Yumi brief format: Goal: what it's for, and what “great” looks like. Copy: my actual words, or a structured draft. Never lorem ipsum. References: 2 to 3 links or screenshots, and why I like each. Assets: logo, images, brand files, if any. Brand: colors, fonts, tone, if I have them. Format: where it lives (Framer page, app screen, PDF…) and any sizes. Goal, Copy and References are never skipped. When I ask you to send a request: 1. Show me the brief and wait for my OK. 2. Then post it as a new card in my Backlog list. Full documentation and three real briefs: https://yumidesign.co/os Keep my key and token private.
That’s it. Now just say “send this to my board” and Claude writes the brief and files it for you.
