Merchant Center 帐号会存储购物广告系列的商品信息。
您可以通过商品 Feed 将商品信息上传到您的商家帐号。
您可以在 Merchant Center 中或通过 Content API for Shopping 创建同时上传多个商品的商品 Feed。通过 Content API for Shopping,您还可以上传和更新单个商品。
通过 Feed 和 API 上传,新上传的商品需要接受数据质量检查,这最多可能需要 72 小时才能解决。在此期间,这些产品将处于 pending 状态。如需了解详情,请参阅产品状态定义页面。
如果您在某个电子商务平台中已有商品信息,则可以将该电子商务平台关联到 Merchant Center,并自动共享这些信息。请与您的电子商务平台提供商联系,了解是否存在任何可用于与 Merchant Center 共享商品信息的连接器。

The Content API\nfor Shopping also lets you upload and update individual products.\n| **Objective:** We strongly recommend you use the Content API for Shopping. The Content API is much more flexible and scalable than the manual steps.\n\nWith both feed and API uploads, newly uploaded products are subject to data\nquality checks that may take up to 72 hours to resolve. These products will have\nthe `pending` status in the meantime. See the [Product status definitions](//support.google.com/merchants/answer/160491) page\nto learn more.\n\nIf you already have product information in an eCommerce platform, you may be\nable to connect that eCommerce platform to the Merchant Center and have the\ninformation shared automatically. Check with your eCommerce platform provider to\nsee if any connectors exist for sharing product information with the Merchant\nCenter.\n\nAll products must adhere to the [Product data specification](//support.google.com/merchants/answer/188494). Read\nthrough the specification to understand what product attributes must be provided\nfor a product to be valid. Some types of products require different attributes\nthan others.\n\nManual steps\n------------\n\nIf this if your first time creating a feed, it may take a few tries to\nresolve all the errors. See the [Google Advertiser Community](//www.en.advertisercommunity.com/t5/Google-Shopping-and-Merchant/bd-p/google-shopping) for help.\n\n1. See [About feeds](//support.google.com/merchants/answer/188478) and [File formats for product data](//support.google.com/merchants/answer/160567) to plan the structure of your feed.\n2. Follow the steps in [Upload a feed](//support.google.com/merchants/answer/188477).\n\nAutomatic steps\n---------------\n\nYou can use the Content API for Shopping to bulk upload product information\nthrough feeds and to send individual product information.\n\nYou can only automate scheduled feeds.\n\n- Use the [`datafeeds`](/shopping-content/reference/rest/v2.1/datafeeds) service to create, update, and delete registered feeds.\n- Use the [`products`](/shopping-content/reference/rest/v2.1/products) resource to upload and update individual products.\n\n See the [Product data specification](//support.google.com/merchants/answer/188494) to learn which fields are required\n for your specific product.\n\n Use [`products.insert`](/shopping-content/reference/rest/v2.1/products/insert) to upload product information. If you're sending\n multiple products at once, see [Sending batch requests](/shopping-content/guides/how-tos/batch).\n\n Product errors are signaled with a non-2xx HTTP status message, and\n the body of the response contains more information.\n\n Even successfully uploaded products may return warnings that you\n should examine to improve your proudct data. See the [common errors](/shopping-content/guides/how-tos/common-errors) guide\n for more information.\n\n You can use the [`productstatuses`](/shopping-content/reference/rest/v2.1/productstatuses) service to see the status of products on\n you account.\n\n Individual products uploaded through the Content API for Shopping\n expire either after 30 days or on their manually set expiration date,\n whichever comes first.\n\n In order to keep products from expiring, they must be updated or\n re-inserted. It's important to schedule a regularly occurring refresh to the\n Content API for Shopping's [`products`](/shopping-content/reference/rest/v2.1/products) endpoint."]]
