This document provides an introduction to REST web services. It defines REST and compares it to SOAP web services. REST uses HTTP and is stateless, lightweight and more data-driven than SOAP. It also describes the common HTTP methods used in REST (GET, POST, PUT, DELETE) and how they map to create, read, update and delete operations. The document demonstrates how to create a REST request and test case in SoapUI by retrieving JSON data from a sample RESTful API.
