Invalid MerchantOrderItemID.
This error occurs when we are unable to recognize the MerchantOrderItemID you provided. The
MerchantOrderItemID must exactly match a value you previously provided in an order
acknowledgment feed. Common reasons why this error may occur include:
-
You accidentally provided the AmazonOrderItemID instead of your own
MerchantOrderItemID.
-
You transposed or omitted characters in your MerchantOrderItemID.
-
Your MerchantOrderItemID was never created in the Amazon system because of an error in a
previous order acknowledgement feed.
To resolve this error:
-
Review you’re the MerchantOrderItemID field. If the AmazonOrderItemID is in that field,
provide a valid MerchantOrderItemID. If the field has a typo, correct this.
-
Update your acknowledgment feed with the corrected MerchantOrderItemID and resubmit your
data.
