The document outlines the integration of Hybris Commerce backoffice with a call center system using API calls to manage customer service events. It describes a flow where the UCCX system triggers an HTTP RESTful API call to the Hybris OCC API, which then publishes a backoffice event that a custom widget listens for to render a popup in the customer service backoffice module. The implementation is demonstrated using Groovy code, but it can also be executed in Java.
