Amazon MWS Upload Invoice

See more Amazon MWS Examples

Demonstrates how to upload an invoice using _UPLOAD_VAT_INVOICE_FeedType to submit an invoice for an order. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Connect to the Amazon MWS REST server.
// 
// Make sure to connect to the correct Amazon MWS Endpoint, otherwise
// you'll get an HTTP 401 response code.
// 
// See Amazon MWS endpoints and MarketplaceId values

rest.set_host("mws.amazonservices.com");

// MarketplaceList.Id parameter �This should be the marketplace in which the order was placed. Only one marketplace must be used per order.T
// Here are the marketplace ID's
