Any way to log webservice request parameters?

Hi there,

I'm trying to debug an application that I have that is sending requests to my moodle server registered as an external webservice. I can see the webservice requests in the mdl_logstore_standard_log MySql table, but unfortunately, that log does not appear to include parameters passed along with the request. Is there any way to get that data, or to start logging it? I would love to be able to see these logs to be able to troubleshoot the issue I'm encountering.

Thanks!
