Set up the preferences
Add the 'RestfulJsonNotificationService.serviceUrls' preference and specify your service(s).
You may add more than one Url by clicking on the "Add Value" link
Using Optional Parameters
The parameters included with the call to a REST service are set in the Spring configuration. See file applicationContext.xml (notification-portlet-webapp/src/main/webapp/WEB-INF/context/). In that file the Spring bean restfulJsonNotificationServices is configured accordingly and you can revise the "urlParameters" property based on your needs. By default, the url pattern will be similar to this: "https://university.edu/yourFeed/{username}"
