# Trello

> Connect Trello to your Atako agents — 17 read and 23 write actions.

Let your agents manage your Trello boards — create and move cards, keep lists, checklists, labels and comments up to date.

## Connection

* **Authentication**: API key (key:token).

<Note>
  Trello → [https://trello.com/power-ups/admin](https://trello.com/power-ups/admin) → New → fill in the Power-Up form → open it → "API key" tab → Generate a new API key and copy it. Then click the "Token" link next to the key, approve access (grants read/write for your account), and copy the token. Paste both as key:token.

  See [Trello's documentation](https://trello.com/power-ups/admin).
