Here are 3 simple steps to give you a head start with WCS member Web services, once you understand the input/output request format for a Web service it will be easy to build an external application which can consume these services.
Step 1: Load the service definition WSDL in SOAP UI project
Step 2: Review the Nouns to look for actions they support.
Member service support 3 types of Nounsa)Person http://publib.boulder.ibm.com/infocenter/wchelp/v7r0m0/topic/com.ibm.commerce.services.doc/Member/Person/noun.htm
b)Organization

c)MemberGroup
http://publib.boulder.ibm.com/infocenter/wchelp/v7r0m0/topic/com.ibm.commerce.services.doc/Member/MemberGroup/noun.htm
Step 3: Review the corresponding actions Request/Response XML
E.g let's say we want to use "Authentication" webserviceFollowing is a sample XML
http://publib.boulder.ibm.com/infocenter/wchelp/v7r0m0/topic/com.ibm.commerce.services.doc/Member/Person/AuthenticatePassword_Req.xml
Use this to build the corresponding request for the action in SOAP UI project
Request XML:
