Step 8: Click Next to maintain SOAP Protocol
Here we can keep default settings.

Step 9: Click Finish then you will go back to the Details of Service Definition

Step 10: To get WSDL URL by clicking Open Service WSDL Generation

Here you can copy WSDL URL.

Step 11: If you want to test the API with SOAPUI, you can create SOAPUI project with the WSDL URL
