Merchant Center アカウントには、ショッピング キャンペーンの商品情報が保存されます。
商品フィードを使用して、販売アカウントに商品情報をアップロードします。Merchant Center または Content API for Shopping を使用して、複数の商品を一度にアップロードする商品フィードを作成できます。Content API for Shopping では、個々の商品のアップロードと更新も行えます。
フィードと API のどちらのアップロードでも、新しくアップロードされた商品はデータ品質チェックを受け、解決に最大 72 時間かかることがあります。その間、これらのプロダクトのステータスは pending になります。詳しくは、商品ステータスの定義ページをご覧ください。
e コマース プラットフォームに商品情報がすでにある場合は、その e コマース プラットフォームを Merchant Center に接続すれば、情報を自動的に共有できます。Merchant Center と商品情報を共有するためのコネクタがあるかどうかについては、e コマース プラットフォーム プロバイダにお問い合わせください。

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."]]
