There are 6 guidelines or design principles that a true RESTful application must have: The four basic verbs that primarily get used are:Īdditionally, REST can provide responses in a variety of formats such as XML, CSV, JSON, or RSS, allowing you to choose an output that is easiest to parse within your programming language. REST uses HTTP 1.1 verbs to perform tasks. However, REST is lighter-weight and is usually easier and simpler to work with than other Web Services. Because REST relies on the web and pre-existing technologies, it is limited to what it can do. REST, introduced by Roy Fielding, is an architectural style that commonly uses HTTP to transmit data over the web. Because of the level of security that SOAP APIs have to offer, it is recommended that organizations handling sensitive data use SOAP APIs. WS-Security is built on the standards set by the Organization for the Advancement of Structured Information Standards (OASIS) and the World Wide Web Consortium (W3C), and uses a mixture of XML encryption, XML signatures, and SAML tokens for authentication and authorization. SOAP APIs use WS-Security to ensure that data is transferred securely. This is extremely important and useful when working with a Web Service that is not yours, as you won’t have to guess what is causing an error.
