WooCommerce Logiwa Integration

OK, I have a client using WooCommerce and the warehouse for the wholesale products uses Logiwa for inventory and stock information.

While Logiwa claims that they have “WooCommerce Integration”, they not only have no documentation about this, but no PHP sample code whatsoever for their API (C# only).
I’m hoping to get any information from anyone who might have any knowledge about this topic.
I searched this board and no topics match. Thanks everyone!
