For example, you might use this API to display a custom welcome message such as "Hello John, your Chapter 1 Reading Assignment is due today."
The Content Extensions APIs can only be invoked from within a course the user is accessing and cannot be called outside of the LearningStudio User Interface. You do not need to include course or user identification in the URL when making the request, as this information is taken from the User Interface session.
Note: This is the only data that can be dynamically included inside the visual editor. The RESTful Course APIs cannot be called from inside LearningStudio.
