It doesn’t really have any setup standards and ignores the details of data implementations as well as syntax. However, its main focus is on the role of elements and interaction between the others.
  • SOAP. Simple Object Access Protocol doesn’t have such popularity as the previous one and its share is 26%. It is used for sending the messages or small amounts of data using HTTP. Also, SOAP tunnels easily over firewalls and proxies, however, the process occurs to be slow.
  • JAVASCRIPT/ XML-RPC. This protocol has a raw of advantages like one method of serialization and security simplicity. Its functionality is a bit similar to REST’s JSON.
