In CentraSite, you document a REST API as an asset instance of the type REST Service or Virtual REST Service.

These APIs are typically collections of resources.

For example, consider an API that is defined to support an online phone store application. Assume, this sample Phone Store API currently has a database that defines the various brands of phones, features in the individual phones, and the inventory of each phone.

The Phone Store API is used as a sample to illustrate how to model URL patterns for resources, resource methods, HTTP headers and response codes, content types, and parameters for request representations to resources.
