Added custom invoice attachments for business shipments

Details

Now, within the invoice array, you can:

  • specify whether the invoice is client-provided;

  • define the invoice type and its attributes;

  • attach a scanned invoice file.

This allows the system to automatically determine the correct customs codes and synchronize data between the client, Nova Post systems, and customs authorities.
