I have a problem with POST_ORDER_FULFILLMENT_DATA and specialy with ShipFromAddress.
It is documented in OrderFulfillment.xsd that a field ShipFromAddress can be included in this request and I tested a lit of times with different data and the answer was “We are unable to process the XML feed because one or more items are invalid. Please re-submit the feed.”
Is it possible to add this field what information I have to put in it?
