Amazon SP-API Feeds API：JSON_LISTINGS_FEED提交成功但部分价格未更新

我按照官方文档使用Feeds API提交了JSON_LISTINGS_FEED，API流程执行成功，卖家中心也没显示错误，但只有约一半的商品价格更新成功，剩下的24小时后还是没变化。怀疑是Feed内容有问题，求帮忙排查。提交的Feed内容如下：

排查方向及解决方案 #

• 核对Product Type准确性
  每个SKU的productType必须和亚马逊后台商品的实际品类完全匹配，比如SPORTING_GOODS是大类，若商品属于更细分的子品类，用大类可能导致更新被静默拒绝。建议逐个检查未生效SKU的后台品类，修正productType字段。

• 优化PATCH操作路径
  当前直接替换整个purchasable_offer对象，部分品类可能需要更精准的路径。尝试改为直接更新价格值：

  {
    "op": "replace",
    "path": "/attributes/purchasable_offer/0/our_price/0/schedule/0/value_with_tax",
    "value": 37857
  }
  

  这种方式减少了对象结构冲突的概率。

• 检查SKU状态与格式
  确认未生效SKU在后台处于可售状态，没有拼写错误（大小写、连字符差异）。部分SKU可能因审核、锁定等后台限制导致价格更新失败。

• 获取Feed详细处理日志
  通过Feeds API的getFeedDocument接口拉取处理后的结果文档，里面会记录每个message的具体状态，即使卖家中心没显示错误，也能找到静默失败的原因。
