The most prevalent of SOAP libraries for Perl is SOAP::Lite it is the oldest and most documented. Though for all of its documentation it can be quite painful to figure out how to use it. First make sure you’ve read Part 0 to set up the server. Once that’s done let’s look at the most simple way to interface with this server. In our first example we need to send a request to getCountries, which is a method provided by the API.

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.
