Trello

Let an agent move cards across your boards without your password. It reads boards, lists and cards, creates, updates, moves, archives and labels cards and comments on them, and deleting a card can wait for a person.

How do users connect? Each one brings their own Trello.

  1. 1.Call for the userYour server invokes the action for the signed-in user. Without a Trello connection, the SDK throws EndUserNotConnectedError with a connect link.
  2. 2.The user pastes a keyThe link opens a form that shows where in Trello's settings to create the key. The link lasts 10 minutes and works once.
  3. 3.Anlyon checks itThe key is checked with Trello before it is kept, and bound to api.trello.com. It is never shown back.
  4. 4.Your server confirmsYour server confirms the connection for the user who is signed in, and the call goes through.

Guardrails. Suggested limits and approvals, for you to review.

  • 200 cards updated a day
  • 300 cards moved a day
  • 100 cards archived a day
  • 50 cards restored a day
  • 200 comments a day
  • 300 labels added a day
  • 300 labels removed a day
  • 20 cards deleted a day

Suggested approvals

What the key must allow

  • An API key from a Power-Up you create, and a token for your account
  • The token acts as you on every board you can reach

Good to know

  • Create the token from an account that is a member of only the boards your agent should work in.
  • A comment or a description is bounded to 4,000 characters, because Trello takes them in the URL.

For your own account

  1. 1.In Trello, create a Power-Up at trello.com/power-ups/admin and generate its API key.
  2. 2.Use the key's Token link to create a token for your account.
  3. 3.In Anlyon, open Actions, then Integrations, choose Trello and paste the key and the token.
  4. 4.Anlyon checks them with Trello before storing them. They become a secret named TRELLO, bound to api.trello.com.

Trello in your code. For one of your users, or for your own account.

Act for one of your users from your server, or connect your company's own Trello with the CLI.

All integrations

Let your agent act for your users, safely.

A few lines of server code, then send a user a connect link. Nothing to host.
