Are there any UPS WorldShip integration APIS or Libraries out there for .net? I've been tasked with integrating our Sample Order application (A VB.Net/SQL Server app) with UPS, and having it write .xml files for the auto import feature though serialization has gotten my foot in the door- but some of the more advanced shipment options such as international customs options are completely undocumented.
How did you get UPS integration up and running? Did you have any 3rd party help doing it? Is there a better location for documentation I'm just missing?
EDIT: What I'm trying to do is create new shipments based on order data in my database and then update those orders with the tracking number the shipment received from UPS. The orders have the shipping method designated, 2nd Day Air, Ground, or International. About 50% of the orders are international.

Look at the NexxStatus and ShipRush products at the bottom. Hopefully between those you'll be able to find something.
