Trello

Turn the page you are on into a Trello card with the link attached, and update or move cards across your boards.

Pick a saved connection in the Credential field, or create one from there. It signs in with a Basic Auth.

What it does

The Trello node works on three kinds of things (Resource):

• Card: create a card in a list, change its title or description, move it to another list, or attach a link to it.
• Board: list your boards, to find a Board ID.
• List: list the lists (columns) of a board, to find a List ID.

When you fill Source URL on Card → Create, the node does two things: it adds a Source: line with the link to the end of the description, and it attaches the link to the card, so it shows in the card’s attachments with a preview.

When to use it

• Capture a page as a card in a “To read” or “Ideas” list.
• Add a card to a team board when a form is filled or a page changes.
• Move a card to “Done” when a workflow finishes the task.
• Attach a generated report or a related page to an existing card.

For personal to-dos, use Todoist. For software issues, use Linear or GitHub.

Call the Trello API yourself with the HTTP Request node, and pick the same connection in its Credential field.

Use HTTP Request →

• List ID and Target list ID are the id of a list (a column), not of a board. Run Board → List, then List → List with your Board ID, and copy the id of the list.
• Board ID can also be the short code in a board’s address: https://trello.com/b/AbC123xY/my-board gives AbC123xY.
• Card ID comes from the id of a Card → Create result, for example {{ $('Trello').id }}, or from the short code in a card’s address (https://trello.com/c/<code>/…).
• Position puts the new card at the Top or Bottom of the list.

Outputs

• Output

• Card → Create, Update and Move return the card, including its id, name, desc, idList and url (the link to open it in Trello).
• Card → Attach URL returns the new attachment, with its id, name and url.
• Board → List returns one item per board with id, name and url; List → List returns one item per list with id and name.

Dependencies and credentials

• Credential (connection, Basic Auth): required. See Connect Trello.

Trello uses an API key and a token, saved together as a Basic Auth credential:

1. Open trello.com/app-key while signed in to Trello. If Trello asks you to create a Power-Up first, create one in its admin page; its API key tab gives you the key.
2. Copy the API key.
3. Next to the key, follow the Token link, allow access, and copy the token.
4. Create a Basic Auth credential with the API key as Username and the token as Password. See Create a credential.

The token can act on all your boards, so keep it private.

Example workflow

1. A Context Menu trigger adds “Add to Trello” to the right-click menu.
2. Get Page Metadata reads the page’s title and url.
3. Trello, Card → Create, List ID of your “Ideas” list, Card title {{ $input.title }}, Source URL {{ $input.url }}, Position Top.
4. Browser Notification shows Card added, with the card’s {{ $input.url }}.

Common issues

• “Trello needs a Basic Auth credential with the API key in Username and the token in Password.” The credential is missing a value or is not Basic Auth. Fill both fields.
• “Trello API Error: 401 … the API key or token is invalid or expired”. The key and token do not belong together, are swapped, or the token was revoked. Generate a new token next to your key and update the credential.
• “Trello API Error: 400 … invalid id”. A List ID, Card ID or Board ID is wrong. A board id was probably used where a list id is needed; use List → List to get list ids.
• The run is blocked in the web app. Trello runs through the browser extension. Install the extension and allow Trello for this workflow when asked, or run the workflow from the extension. See Running extension-only integrations in the web app.
