Retrieve all documents associated with a specific order. Documents may include invoices, shipping labels, packing slips, customs declarations, and tax receipts. EcartAPI normalizes document metadata across platforms that expose order documents differently — some provide downloadable URLs while others generate documents on demand.

This endpoint is essential for automating document delivery to customers, feeding documents into accounting systems, and maintaining compliance records for cross-border shipments.

Note: Available document types and metadata fields vary by platform.
