Merchant Center 帳戶會儲存購物廣告活動的產品資訊。
您透過產品動態饋給將產品資訊上傳至商家帳戶。您可以在 Merchant Center 中，或透過 Content API for Shopping 建立產品動態饋給，一次上傳多項產品。Content API for Shopping 也可讓您上傳及更新個別產品。
同時上傳動態饋給和 API 後，新上傳的產品都必須接受資料品質檢查，最多可能需要 72 小時才能解決。在此期間，這些產品將處於 pending 狀態。詳情請參閱產品狀態定義頁面。

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."]]
