亚马逊 MWS - 更新产品数量

Question

我正在使用 amazon api 使用“_POST_INVENTORY_AVAILABILITY_DATA_”feedtype 来更新产品的数量，例如，

<?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>

但是当我尝试一次更新 15k 或更多产品时，使用 magento 收集数量的产品在几个小时后也没有在亚马逊更新。这是正确的方法还是我需要使用任何其他方法？

谁能帮帮我？

提前致谢。

Answer 1

尝试使用 _POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA_ feedtype 并在 https 请求的正文中发送 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），然后是包含值的行（由制表符分隔）。

Answer 2

引用亚马逊 MWS API：

每个 Feed 的大小限制为 2,147,483,647 字节 (2^31 -1)。如果你 有大量数据要提交，您应该提交较小的提要 通过分解数据超过 Feed 大小限制，或提交 Feed 过了一段时间。一种好的做法是提交带有 30,000 条记录/项目的大小限制或在一段时间内提交提要 时间，例如每隔几个小时。
