Does anyone know of an API that enables you to print shipping labels from and to anywhere in the world? I'm creating an app that requires labels with an origin and destination that can be any country.
For example, one shipping label could be from a country in Europe to the USA. Another could be from Brazil to Europe. And another could be from the Philippines to Chile. I need the API to help me find a carrier that can ship between the particular origin and destination, then determine the rate, then print the label.
