Web services are Application based Programming Interfaces (APIs) or web APIs that are accessed through Hyper Text Transfer Protocol (HTTP) to execute on a remote system hosting the requested services. A restful web service is a budding technology, and a light weight approach that do not restrict the client-server communication. The Open Authorization (OAuth) 2.0 protocol enables the users to grant third-party application access to their web resources without sharing their login credential data. The authorization server includes authorization information with the access token and signs the access token.
