ShipEngine covers international shipments through any major carrier that we support. The packages must ship from US, Canada, Australia, or United Kingdom.
The difference between domestic and international labels is that you’ll need to make a customs object along with the label request for international shipments. In the response, you will get a label that you can download and print to ship your package.
Some carriers might also require a customs form to be included with your international shipment, which will be flagged as “form_download” in the JSON response. Make sure to download the form and include it with your shipment if it’s in the response.
