The VineOS Commercial Invoice API generates printable Commercial Invoices for your international shipments. The API uses JSON over HTTPS and authenticates via API Key.
Use the Commercial Invoice API to email a copy of each Commercial Invoice to the shipper/sender. In addition, the API will automatically retrieve HS Codes, calculate total weights, and the total invoice amount. A web client is also available: http://documents.vineos.io/commercial-invoice/. See the project page for more information and access to an API test client.
