如何确定亚马逊本身是否通过API销售商品？

提问于

我正在使用“GetLowestOfferListingsForASIN”MWS API来获得亚马逊为ASIN销售的最低价格 . 我的要求是找出亚马逊自己是否出售最低价格 . 由于API未返回任何卖家ID，因此我无法确定卖家是谁 .

我知道“AnyOfferChanged”订阅确实会返回卖家ID，但它只会通知我销售的商品 . 但我有很多我不卖的ASIN，我仍然需要亚马逊销售的价格 .

任何人都可以告诉我，如果可以通过API或任何其他方法 .

提前感谢你们 .

    据我所知，这是不可能的，他们故意不通过MWS API向卖家提供价格信息 . 我想要相同的信息，并且无法收集任何比FBA更好的东西 . 如果你找到另一种方式，我有兴趣知道 .

    这是可能的，但有点间接 . 您必须通过Subscription API订阅AnyOfferChangedNotification . 然后，您可以处理Amazon Simple Queue Service (SQS)队列中的消息 . 此消息将包含 SellerID ，您可以识别亚马逊 .

    通知将如下所示：

    <Notification>
<NotificationMetaData>
    <NotificationType>AnyOfferChanged</NotificationType>
    <PayloadVersion>1.0</PayloadVersion>
    <UniqueId>c027f13372c522</UniqueId>
    <PublishTime>2015-11-03T16:24:13.907Z</PublishTime>
    <SellerId>1337</SellerId>
    <MarketplaceId>A1PA6795UKMFR9</MarketplaceId>
</NotificationMetaData>

<NotificationPayload>
    <AnyOfferChangedNotification>

        <OfferChangeTrigger>
            <MarketplaceId>A1PA6795UKMFR9</MarketplaceId>
            <ASIN>B00FQ8AVHS</ASIN>
            <ItemCondition>new</ItemCondition>
            <TimeOfOfferChange>2015-11-03T16:24:13.664Z</TimeOfOfferChange>
        </OfferChangeTrigger>

        <Summary>

    在这个例子中，我切断了其他优惠，使其缩短一点 . 正如您所看到的， Notification.NotificationPayload.AnyOfferChangedNotification.Offers.Offer.SellerId 的值是 A3TZZ7DOC6G9UH . 亚马逊为其卖家帐户拥有自己独特的SellerId .

    如果您已经设置了这样一个系统并跟踪所有产品的这些信息，您将会知道亚马逊销售的产品 . 我这样做是为了大量的产品，它工作正常 .

    您需要使用产品广告API .

    ItemSearch和ItemLookup操作支持可选的参数MerchantId，可用于过滤MerchantId的结果 .

    要查找亚马逊本身是否为卖家，请设置 MerchantId = Amazon

    在这里阅读API文档http://docs.aws.amazon.com/AWSECommerceService/latest/DG/ItemSearch.html http://docs.aws.amazon.com/AWSECommerceService/latest/DG/ItemLookup.html
