Commerce server provides flexibility to access its sub-systems using web services. The main drawback is web service documentation – which service to call for a particular action. If you are little bit intelligent, you can achieve this very easily.
Go to IIS and enable logging as shown in the image.
By enabling this functionality, IIS will start logging all hits to web server in the follow location
C:\WINDOWS\system32\LogFiles\W3SVC1
Note: Make sure you enable method name logging. For more information on enabling IIS logging click on below link

Now open any commerce server business tool and run any desired action. For example, you would like to approve a discount in marketing system. Just perform that action in business tools and check the log file. you can see which method the business tool has called. Enjoy….
