Asside from the built-in routines, VPCART has add-ons available for other shipping types. These can be added in the “Setup Other Shipping” area of the shipping setup page, as can any shipping routines you write yourself.
To add a shipping routine, simply enter a name for the routine in the Shipping Method field and the name of the file that does the processing in the File Name field.
If you are using an add-on, it will come with detailed installation instructions which cover any extra steps you need to take.
Among the shipping calculation providers VPCART integrates with are:
•UPS Realtime (see section below)
•UPS by Database Lookup
•Australia Post realtime
•Canada Post realtime
•Fedex database lookup
•USPS Realtime lookup
•Intershipper
Note: These add-ons do not form part of the official supported VPCART product. It is possible for these providers to change their rules or requirements and we cannot guarantee that VPCART will support these changes. Some of these providers require that you register before using their services and most of the real-time interfaces require the Microsoft XML DLL to be installed on your server.
