# Extract invoices

Use the **getInvoices** method to extract shopper invoices from the 2Checkout 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.
