You can display all SOAP request/response data in IntegrationServer stdout.
Browse to IS-> Settings → Extended → Show and hide keys , and click on
watt.server.SoapRPC.debug
watt.server.SoapRPC.trace
watt.server.SoapRPC.verbose
Save changes and now go to Settings → Extended → Edit extended settings
Change values for those 3 from false to true.
Restart IS and check stdout.
You would get all SOAP exchange information… if you only want the requests/response I believe the .trace option was ok.
Good luck.
