How to test Webservice?

I can test my webservice successfully in SOAPUI by using the below setting:

  1. Endpoint
  2. Resource
  3. Request message

But, I don’t know to test it and config on Katalon ? I got the error “Service Function is empty” (I don’t have wsdl file)

I resolved this by using restful service and changed the url to: http://10.53.21.18:5999/global/vn/rpgw/modulekenh/sendstore/1.0

Thanks.
