Amazon MWS Feed API Issue in updating Order status

Question

I am working on amazon mws feed api to update the order status from my site.
when i call to SubmitFeed Api, it is submitted successfully. But, when i call to GetFeedSubmissionResult, its returns me an error stating :

        <Result>
            <MessageID>1</MessageID>
            <ResultCode>Error</ResultCode>
            <ResultMessageCode>25</ResultMessageCode>
            <ResultDescription>We are unable to process the XML feed because one or more items are invalid. Please re-submit the feed.</ResultDescription>
        </Result>

Here is the my xml :

<?xml version="1.0" encoding="UTF-8"?>
<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">
    <Header>
        <DocumentVersion>1.01</DocumentVersion>
        <MerchantIdentifier>Maxvite Store</MerchantIdentifier>
    </Header>
    <MessageType>OrderFulfillment</MessageType>
    <Message>
        <MessageID>1</MessageID>
        <OrderFulfillment>
            <AmazonOrderID>123-5454545-5454545</AmazonOrderID>
            <MerchantOrderID>123456</MerchantOrderID>
            <MerchantFulfillmentID>123456</MerchantFulfillmentID>
            <FulfillmentDate>12-02-2013T04:23:00Z</FulfillmentDate>
            <FulfillmentData>
                <CarrierCode>UPS</CarrierCode>
                <ShippingMethod>UPS Ground</ShippingMethod>
                <ShipperTrackingNumber>123456</ShipperTrackingNumber>
            </FulfillmentData>
         </OrderFulfillment>
    </Message>
</AmazonEnvelope>

Thanks in advance

Answer 1

I have changed "CarrierCode" from 'Fed Ex' to 'FedEx' - Removed the space and it is working fine now.

Answer 2

Remove the tag: 123456

it should be either "AmazonOrderID" or "MerchantOrderID".

You can leave out the cantainer.

Answer 3

You're missing the <item> section:

<Item>
     <MerchantOrderItemID>1234567</MerchantOrderItemID>
     <MerchantFulfillmentItemID>1234567</MerchantFulfillmentItemID>
     <Quantity>2</Quantity>
</Item>

Although the XSD shows minOccurs="0", it may required in some circumstances. (I've found some weird behaviors with some of the feeds)

That being said, the MWS forum is reporting an identical issue affecting multiple people, so it could be a MWS thing...

Answer 4

Your feed does not validate against the XSD schema. You cannot specify both AmazonOrderID and MerchantOrderID in the same feed (it is specified as choice in the OrderFulfillment.xsd)

Also, your FulfillmentDate should read 2013-02-12T04:23:00+00:00.

The following feed is changed accordingly and does validate:

<?xml version="1.0" encoding="UTF-8"?>
<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">
    <Header>
        <DocumentVersion>1.01</DocumentVersion>
        <MerchantIdentifier>Maxvite Store</MerchantIdentifier>
    </Header>
    <MessageType>OrderFulfillment</MessageType>
    <Message>
        <MessageID>1</MessageID>
        <OrderFulfillment>
            <AmazonOrderID>123-5454545-5454545</AmazonOrderID>
            <MerchantFulfillmentID>123456</MerchantFulfillmentID>
            <FulfillmentDate>2013-02-12T04:23:00+00:00</FulfillmentDate>
            <FulfillmentData>
                <CarrierCode>UPS</CarrierCode>
                <ShippingMethod>UPS Ground</ShippingMethod>
                <ShipperTrackingNumber>123456</ShipperTrackingNumber>
            </FulfillmentData>
         </OrderFulfillment>
    </Message>
</AmazonEnvelope>

Hope this helps.
