The WSDL Inspector allows you to define, from the WSDL of a web service, an External Object of the WSDL type and the required data types in GeneXus to use the web service in a transparent manner, without worrying about the protocols involved in the process and its definition.
Access the WSDL Import wizard through Tools/Application integration and indicate the WSDL path:
Indicate the name to be given to the External Object (EO), its description, folder and prefix.
Finally, all the information related to the WS that is obtained from the WSDL is displayed.
Once we've done the import, we'll have created the EO of the WSDL type with all the properties required to use it.
