Introduction : Overview of REST Web services in OpenEdge : Standards supported by OpenEdge REST Web Services : HTTP
OpenEdge REST Web services employs HTTP for accessing and manipulating resources. In general, HTTP is the defacto standard for REST.
OpenEdge REST uses HTTP methods (GET, POST, PUT, DELETE for example) to interact with resources that are mapped to URIs. (Compare with the SOAP-based OpenEdge WSA, which only uses HTTP as a transport protocol, and uses complicated WSDL mappings to provide access to procedures.)
