In this chapter, we learned about a number of powerful ServiceNow APIs, including GlideUser, GlideSystem, GlideSession, and more. We also learned about some exclusively client-related APIs, such as GlideAjax and the g_form API. This chapter can serve as a reference for some of the ServiceNow APIs we'll be using in the coming chapters, so feel free to bookmark it, and flip back now and then for reference.
