Setup Guide

This guide walks you through obtaining a Trello API key and token required to use the Trello connector.

Prerequisites

• An active Trello account. If you do not have one, sign up for free.

Step 1: Create a Power-Up in the admin portal

1. Log in to your Trello account.

2. Navigate to the Trello Power-Ups admin portal.

   

3. Select New to create a new Power-Up.

4. Fill in the required fields (name, workspace, and a placeholder iframe connector URL) and select Create.

   

Step 2: Generate an API key

1. After creation, select the Power-Up name to open its settings.

2. Select the API Key tab.

   

3. Select Generate a new API Key and copy the displayed API Key.

   

note

If you previously generated a key at trello.com/app-key, that flow has been replaced by the Power-Up Admin portal.

Step 3: Generate an API token

1. On the same API Key page, select the Token link next to your API key.

   

2. Review the permissions requested and select Allow.

3. Copy the generated Token.

   

tip

Store the API Key and Token securely. Do not commit them to source control. Use Ballerina's configurable feature and a Config.toml file to supply them at runtime.

warning

The token grants access to your Trello account. Treat it like a password and revoke it if compromised.
