維護產品動態饋給
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
摘要
部分產品資料 (例如價格和供應情形) 會隨時間自然而有變動。
您需要定期維護產品動態饋給,以便隨時更新這項資訊。
您可以使用補充動態饋給和 Products API 更新產品資料。補充動態饋給只能在 Merchant Center UI 中建立,且必須連結至主要動態饋給。
手動步驟
如要利用補充動態饋給維護商品目錄,請參閱「建立補充動態饋給」一文。
您也可以使用商品自動更新功能,隨時更新價格和供應情形資訊。如果價格或供應情形與目前儲存在 Merchant Center 中的資訊不同,Merchant Center 可以利用網站上的內嵌結構化資料更新產品。
商品自動更新功能旨在修正產品價格和供應情形的細微問題,而非更新產品資料的主要方法。除了補充動態饋給和 Content API 之外,建議您也使用這些內容。
如要啟用商品自動更新功能,請按照「商品自動更新功能」一文中的步驟操作。
自動步驟
如要使用 Content API for Shopping 更新資訊產品資訊,請使用 Products API。
您可以使用 insert
和 update
方法建立及更新個別項目。
與產品插入和更新一樣,您可以使用 products.custombatch
方法,將多項商品目錄更新批次處理為單一 Content API for Shopping 呼叫。
