When you scaffold an ePortal Web API presentation project using the Scaffold Unisys Web API Controller for ePortal Data Source Dialog, ePortal generates a controller. For more information on creating a web API RESTful service application, refer to Creating a RESTful Web Service Application.

In particular, ePortal generates the file <controllemame>Controller.cs,  where <controllemame> matches the controller name specified on the Scaffold Unisys Web API Controller for ePortal Data Source Dialog. This file is located in the Controllers folder; it contains the C# code to implement the controller class.

For more information, refer to Programming in the Controller for Web API.
