What is Representational State Transfer (REST)?

Representational State Transfer (REST) is an architectural style for designing web services that are based on the stateless exchange of resources. REST uses uniform and predefined methods, such as GET, POST, PUT, and DELETE, to manipulate resources identified by URIs. REST also supports different formats for data representation, such as XML, JSON, or plain text. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP
