Google checkout offers 2 levels of integration. Level 1 involves posting XML shopping carts to their web service and receiving XML validation.

Level 2 requires writing a web service running on my own server. Google can then pass XML messages to my service to inform my system when various events occur. Thus, I need to write a web service and it must run over ssl.

I've written many CGI scripts and applications before, but I've never written a "web service". I'm wondering if I can do it from within my familiar CGI::Application framework, or do I need to go with something like SOAP::Lite or Frontier?

I'm looking for some validation of my approach before I dive headlong into coding
