Use the administrative console to configure endpoints for Representational State Transfer (REST) application programming interfaces that you want to use during runtime.
If you want widgets to be available in Business Space, you must configure the REST service endpoints for those widgets.
Business Space is a common interface for application users to create, manage and integrate Web interfaces across the IBM® WebSphere® Business Process Management portfolio. Business users can use widgets to work with artifacts from WebSphere Business Monitor, WebSphere Process Server, WebSphere Enterprise Service Bus, WebSphere Business Modeler Publishing Server, and Websphere Business Services Fabric.
