SoapUI can sometimes be a bit cumbersome to use. In that case you can use Wizdler as an alternative. After adding the Wizdler extension to Google Chrome, simply add the URL for the WSDL in de address bar. For example: https://b2b.schuuring.nl:6443/KPNEAIImportWCF/KPNEAIImport.svc?singlewsdl
Now you can select an operation from the WSDL. A dummy input message will be shown. Replace the dummy message with your own test message and hit [Go] to call the service. That’s it, easy to use.
