Trusted by millions, Trello is the visual collaboration tool that creates a shared perspective on any project. Trello’s boards, lists and cards enable you to organize and prioritize your personal and work life in a fun, flexible and rewarding way.


Trello uses OAuth, a developer-friendly delegated access protocol. Quolum has already connected the necessary wires with Trello. Using a sequence of click-throughs, your organization's administrator allows Quolum to make API calls to Trello without getting access to passwords.

Step 1: Initiate a connection to Trello

Click the Connect button from the Connections card. If you are not an admin, you can invite your organization's Trello admin to make a connection to your Trello organization account. When you click on the Connect button, the web browser will navigate to the Trello login page.

Step 2: Log in to Trello

Log in to Trello using your organization's credentials. The exact login mechanism may depend on your Trello plan, and the sign-in mechanism used. You may have corporate SSO such as Azure AD, GSuite, or Okta along with multi-factor authentication. Sometimes you may need to enter an API key and a token, the step by step details of which can be found at Trello API documentation. Once you have successfully logged-in, Trello is going to ask you to grant access to Quolum.


Trello Authentication

Step 3: Provide consent to Quolum

The next screen after login into Trello is the consent screen. On this screen, Trello confirms whether you authorize Quolum to access your organization's data.

Step 4: Back to Quolum

Once you have granted access to Quolum on Trello's website, Trello is going to send you back to Quolum's page in Step 1, where you started. The Connect button on the Connections card would now say Reconnect. Reconnect is used to reauthenticate under circumstances where the access has expired.

Under the hood

Using the OAuth protocol, Quolum now has delegated access to your Trello Workspace. The Quolum server, running on Amazon AWS VPC, will be able to make API calls and retrieve feature-level utilization. Later, this data is crunched and available for visualization on the Quolum dashboard.
