Connect Trello to Fibula

What you'll be able to do

Trello cards are the simplest way to put a human in the loop after a workflow runs. Connect Trello and Fibula can drop a new card on any board, with the document details in the description and the file attached.

Use it for review queues, where each extracted invoice becomes a card on a "To review" list and moves across the board as your team works through them. Use it for vendor follow-up, where a card is created for every missing line item or rejected bill. Use it for onboarding, where each new contract drops a card on the legal team's board with the counterparty and value in the title.

It is a low-friction way to wire documents into whatever Trello workflow your team already lives in.

Set up the Trello app

API Key

1. Go to the Trello Power-Ups Admin
2. Click "New" to create a Power-Up and fill in the form:
   • App name — e.g. "Fibula"
   • Workspace — select the workspace you want to connect
   • Email — your email address
   • Support contact — your email or support link
   • Author — your company or personal name
   • Iframe connector URL — leave blank, not needed for API access
3. After creating, click "Generate a new API key"
   • Copy the API Key and paste it below
   • Under "Allowed origins", add the redirect URI and click Add —

Secret

1. On the same page, copy the Secret value

Connect your credential in Fibula

Open Credentials from the Fibula sidebar and click Add credential. Pick Trello from the provider list, paste in the API Key and Secret you just copied, then click Save and Connect.

Fibula sends you over to Trello to approve the OAuth grant. Sign in to the Trello account that owns the boards you want to write to, approve access, and Trello sends you straight back to Fibula.

The credential is now ready to use in any workflow. You only do this once per Trello account.

What's next

With the credential connected, you don't build anything by hand. Open the Fibula agent chat and tell it what you want in plain English. Something like "Create a Trello card on the AP review board with the vendor name in the title and the invoice attached."

The agent picks the right nodes, points them at your Trello credential, and maps the extracted fields onto the card title, description, and attachments. You review the canvas and click Publish.

For a full end-to-end example of the same pattern, see the Xero guide. Extract from the document, then push to the destination tool.

That is the whole setup. From here it is just workflows.
