View source for REST


With DataFlex you can create RESTful web services as well as consume those web services.

== Client side ==
Consuming [https://en.wikipedia.org/wiki/Representational_state_transfer REST] services was made a lot easier since DataFlex 19.0 when it added native JSON support.

Consume a REST service:
See [https://docs.dataaccess.com/dataflexhelp/mergedProjects/VDFClassRef/cJsonHttpTransfer.htm cJsonHttpTransfer] and [https://docs.dataaccess.com/dataflexhelp/mergedProjects/Welcome/JSON_Parsing_and_Transfer.htm JSON Parsing and Transfer]

You can find a demo of how-to use cJsonHttpTransfer in DAWs WebOrder workspace.

== Server side ==
Creating REST web services has been made easy since DataFlex 19.1 with the introduction of the [https://docs.dataaccess.com/dataflexhelp/mergedProjects/VDFClassRef/cWebHttpHandler.htm cWebHttpHandler] handler.

For an example see the DemoSimpleRestService.wo file in the WebOrder example workspace.

You can create a REST service with earlier DataFlex versions, see [https://www.unicorninterglobal.com/Company-White-Papers-Creating-RESTful-JSON-Web-Services-in-DataFlex-868 here] for how-to do so in DataFlex 19.0, but it is probably better to use DataFlex 19.1 in that case.
