POST /v3/orders/{purchaseOrderId}/acknowledge
This request allows a drop ship vendor (DSV) to acknowledge an order, including all order lines, preferably within four hours of receipt of the order.
The response to a successful call contains the acknowledged order.
As a good practice, acknowledge orders to avoid underselling.
Only those orders that are in a Created state should be acknowledged.
Orders that are in an Acknowledged state can be re-acknowledged.
This is desirable, for example, when resolving an error response from a previous API call.
Orders with line items that are shipped or canceled should not be re-acknowledged.
