问题
We are using Submit Feed and type is _POST_FLAT_FILE_FULFILLMENT_DATA_ to process the Amazon order. We create a flat file that contains order ID and ship date. But when we hit Submit Feed API for orders then it gives warning message that is:
Order cannot be fulfilled.
Where are we making a mistake?
回答1:
If your order contains more then one item then all API fields are required.
order-id, order-item-id, quantity and ship-date
If order have only one item and you can allow only order ref & date.
But other fields must be blank in the file at same position.
order-id order-item-id quantity ship-date carrier-code carrier-name tracking-number ship-method
You need to send other fields value Null in the file.
This may help you.
