Receive order receipts and tax invoices

Hi,

We added a new REST API endpoint for receiving order receipts as PDF files. So now you have two options for order "invoices":

• Receive links to PDF files for all order tax invoices: https://api-docs.ecwid.com/reference/get-order-invoices
  Tax invoices are legally compliant, they can be used as official documents for tax services in your country.
• Receive order receipt as a PDF file: https://api-docs.ecwid.com/reference/get-order-receipt-pdf
  This receipt is not an official document, but it looks much nicer and works better as an order invoice for merchants
