...
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}"

Optional Authentication
Another item to note is that you can also configure the REST web service call to include basic authentication to provide some security. See the notifications.properties (notification-portlet-webapp/src/main/filters/notifications.properties) file for where to set the value for username and password.

# Use this file for filter expressions
