Web Services

4D offers easy consumption and publication of Web Services

Web Services allow an application to call another application using standard protocols such as SOAP and WSDL, independent of the platform or language used.


Since 4D Web Services are written to support Internet standards, they allow 4D developers to build applications that communicate across a local network as well as over the Web.


4D can act as a Web services client, a Web services server, or both.
