For work, one of the major projects we have been working on involves integrating a Wild West Domains(Godaddy) API reseller account to automatically register domain names in our application.  The process of figuring out the API is a monumental task due to the lack of clear current documentation, and a muddle of old documentation that can lead you down a difficult and messy path.

I won't be posting much of any code here, sorry, but will tell you of my experience, and leave the invitation open for those who may need assistance interpreting the API, or debugging impossibly cryptic certification errors.  Interested persons may contact me about purchasing the PHP interface class that I wrote, along with my own documentation.
