  # Note: The official Xero Accounting API for uploading invoice attachments uses
  # POST /Invoices/{InvoiceID}/Attachments/{FileName} (with FileName in the path).
  # The endpoint without a FileName ("/Attachments") is not documented in the
  # official API docs. See: createInvoiceAttachmentByFileName (Xero Node SDK) for reference. \
