We are now posting our Catalina API for Dynamics SL sample client code to GitHub(under a MIT license. Which means that you can use the sample client code for your own purposes).
I am posting the SOAP based sample clients here: https://github.com/CatalinaTechnology/ctAPIClientExamples
I just put up one for customer maintenance. I will be posting more throughout the week (as I get them ready for consumption). If you have any questions, feel free to Contact us. Also, if you are a current Catalina API for Dynamics SL user and have any sample code that you would like to share with others, feel free to forward and we will see if we can get it out there for you.
