This is a prelude to a series on working with SOAP Requests using Perl. For the past 3 months I have been working on a Perl API for CyberSource’s Simple Order API which uses SOAP (I should note, that although I believe most of the API is now stable some area’s still need work, and thus I don’t expect it to reach 1.0.0 anytime soon). First I used SOAP::Lite to do my requests, but I found it confusing to construct the requests that I needed to make.
