Order confirmation interface (OrderResponse)

The electronic transmission of order confirmations allows for structured communication of deviations, for example in case of delivery delays, price changes, or (partial) cancellations. This reduces the need for clarification and improves planning reliability for customers.

If an order is updated, for example due to a delivery date change, the order confirmation can be resent at any time.

Important: Confirmations that only confirm receipt of the order without any statement regarding deliverability will not be processed by Unite.
