维护商品 Feed
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
摘要
某些商品数据（如价格和库存状况）会随着时间而自然变化。
您需要定期维护产品 Feed，以确保这些信息是最新的。
您可以使用补充 Feed 和 Products API 更新商品数据。补充 Feed 只能在 Merchant Center 界面中创建，并且必须与主要 Feed 相关联。
手动步骤
要使用补充 Feed 维护您的商品目录，请参阅创建补充 Feed。
您还可以使用自动商品更新使价格和库存状况信息保持最新。如果商品的价格或库存状况与当前存储在 Merchant Center 中的信息不同，Merchant Center 可以使用来自您网站的嵌入式结构化数据更新商品。
自动商品更新旨在解决商品价格和库存状况方面的小问题，而不是作为更新商品数据的主要方法。建议将这些信息与补充 Feed 和 Content API 结合使用。
如需启用自动商品更新功能，请按照自动商品更新简介中的步骤操作。
自动设置步骤
如需使用 Content API for Shopping 更新商品信息，请使用 Products API。
您可以使用 insert 和 update 方法来创建和更新各个项。
与商品插入和更新一样，可以使用 products.custombatch 方法在单个 Content API for Shopping 调用中批量处理多项商品目录更新。
