An accessible workspace that is friendly to non-designers including developers, product managers, copywriters and more. Zeplin also helps the team collaborate by providing much needed organization and structure to native design files.


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

Step 1: Initiate a connection to Zeplin

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

Step 2: Log in to Zeplin

Log in to Zeplin using your organization's credentials. The exact login mechanism may depend on your Zeplin plan, and the sign-in mechanism used. You may have corporate SSO such as Azure AD, GSuite, or Okta along with multi-factor authentication. Once you have successfully logged-in, Zeplin is going to ask you to grant access to Quolum.


Zeplin Authentication

Step 3: Provide consent to Quolum

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

Step 4: Back to Quolum

Once you have granted access to Quolum on Zeplin's website, Zeplin 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 Zeplin 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.
