A delivery note must contain at least one order line or at least one returnable item. A payload with neither is rejected with a 400 error. This means you can create a delivery note with only returnables (e.g. a supplier picking up empty crates with no goods delivered) by omitting order_lines entirely.

Asynchronous Order Line Processing

After the delivery note is created, the system processes the linking of order lines to their corresponding order packages asynchronously. This means the response returns immediately with the basic delivery note details, but the order line matching may take a few seconds to complete in the background.

To retrieve the fully linked order lines with their matched packages, use the Get Delivery Note Details endpoint after creation.
