Extract invoices

Overview

Use the getInvoices method to extract shopper invoices from the Avangate system based on unique order references. The method returns the binary code for invoices in the PDF file format, Base64 encoded (Base64 is used to represent binary data in the ASCII string format).

getInvoices works for COMPLETE orders for which an invoice was already issued. For refunded orders, getInvoices provides two shopper invoices, one for the original order and the second for the refund, reflecting the repayment made.

In the case of cross-selling orders which contain products from different merchants, getInvoice enables you to re-send only the invoices for your own offerings.
