The system is currently publishing a selection of relatively undocumented SOAP B2B services,
We can provide a demonstration project for Microsoft Visual Studio 2013/15 in C# that demonstrates the use of all services - please create a request in the support tool if you would like to receive it.
However, be aware that the services will be rewritten as REST B2B in 2016, but still centered around exchange of the DVI Files as XML.
