In a system, at least one web server provides an interface to a web-enabled application to a first computing device, with the web-enabled application and the at least one web server belonging to a first domain. An interaction routing module routes a contact event to the first computing device. At least one application server receives and responds to an Hypertext Transfer Protocol (HTTP) request for requested information related to the contact event. The HTTP request is generated by the web-enabled application. An integration module receives the HTTP request from the at least one application server and translates the HTTP request to an application programming interface call to interface with a second computing device storing the requested information in a second domain. A messaging module provides the requested data to the web-enabled application.
