亚马逊MWS - 更新产品数量

Question

我使用了更新的产品的数量亚马逊API使用“_POST_INVENTORY_AVAILABILITY_DATA_”的FeedType一样，

<?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>$merchantID</MerchantIdentifier> 
</Header> 
<MessageType>Inventory</MessageType> 
<Message> 
<MessageID>1</MessageID> 
<OperationType>Update</OperationType> 
<Inventory> 
<SKU>$SKU</SKU> 
<Quantity>8</Quantity> 
</Inventory> 
</Message> 
</AmazonEnvelope> 

<?xml version="1.0"?> 
<SubmitFeedResponse xmlns="http://mws.amazonaws.com/doc/2009-01-01/"> 
<SubmitFeedResult> 
    <FeedSubmissionInfo> 
    <FeedSubmissionId>6791310806</FeedSubmissionId> 
    <FeedType>_POST_INVENTORY_AVAILABILITY_DATA_</FeedType> 
    <SubmittedDate>2013-03-21T19:48:37+00:00</SubmittedDate> 
    <FeedProcessingStatus>_SUBMITTED_</FeedProcessingStatus> 
    </FeedSubmissionInfo> 
</SubmitFeedResult> 
<ResponseMetadata> 
    <RequestId>fd07bf18-4f6a-4786-bdf9-9d4db50956d0</RequestId> 
</ResponseMetadata> 
</SubmitFeedResponse> 

，但是当我尝试使用Magento的装载产品在同一时间更新15K以上的产品亚马逊数小时后的采集数量也不会更新。是正确的方法还是我需要使用任何其他方法？

任何人都可以帮助我吗？

在此先感谢。

Answer 1

尝试使用_POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA_ feedtype并在https请求的主体中发送CSV文件（制表符分隔）而不是XML文件。 csv的第一行应该是：sku价格数量（由制表符分隔），后面是包含值的行（由制表符分隔）。

Answer 2

引用亚马逊MWS API：

饲料大小被限制为每饲料2,147,483,647字节（2^31 -1）。如果您的 有大量要提交的数据，则应通过分解数据或在一段时间内提交供稿 来提交比Feed大小限制更小的订阅源 。一种好的做法是提交大小限制为30000条记录/条目的订阅源，或者在 时间段（例如每隔几个小时）提交订阅源。
