[Forums] OnAfterResponse system action for web service integration

I'm wanting to log my own web service calls for an integration, and I'm writing the web service error response in the OnAfterResponse system action.  The problem is that I don't have the request information in that scope to store with the log record.

How have any of you implemented something like this, where the web service response logging has all the pertinent request/response data that you need?

Thanks in advance!
