Edge - API Explorer

API Explorer contains the most up-to-date documentation for all REST APIs. API Explorer enables developers and partners to easily browse all available REST APIs. Developers can learn about supported features, methods, and metadata. Developers can also download guidelines and access links to sample code.

To access the API Explorer, go to Admin > Tools > Edge > API Explorer. API Explorer can also be accessed directly at the following URL: http://apiexplorer.csod.com

Important: Cornerstone's legacy API authentication framework for APIs, Session Token Service (STS), was deprecated in February 2020 and is fully retired and unavailable as of February 2021.

API Explorer

All the content for applications and features related to REST APIs is available within the API Explorer. Select a resource from the navigation menu on the left side of the page, or enter a search term in the Search bar and click the Enter button on your keyboard to receive relevant documentation results.

Public Access to API Explorer

To access the API Explorer independently of a Cornerstone portal, go to: https://apiexplorer.csod.com/apiconnectorweb/apiexplorer#/

Generic documentation for existing Edge APIs is available from this URL. From the publicly accessible API Explorer page, users with access to an Edge portal can log into their Edge accounts, which redirects them to the Edge Marketplace, provided they have the associated permission. If an anonymous user attempts to try or purchase an API, they are directed to the Edge login screen and prompted to log in.
