Properties   Methods   Events   Configuration Settings   Errors  

Allows you to generate a USPS shipping label for any of USPS international services complete with addresses and barcode.




Generating a shipping label can be done by calling the GetPackageLabel method. You will have to specify the package information, USPS service to be used for shipping this package, origin and destination information, and any special services you want to associate the shipment (such as Return Shipment, etc.), and any other specific information on international shipments.

This component also allows you to request customs forms through the GetFormCN22 and GetFormCP72 methods.
