本指南說明如何使用 Merchant API，管理 Merchant Center 帳戶的非必要電子郵件通知偏好設定。
電子郵件偏好設定適用於你可存取的每個 Merchant Center 帳戶。如果您管理多個帳戶，可以為每個帳戶設定不同的偏好設定。你可以透過 Merchant API 擷取目前的設定並更新。如要進一步瞭解如何透過 Merchant Center 介面管理電子郵件接收設定，請參閱「變更 Merchant Center 電子郵件接收設定」。
商家 API 僅支援管理「新聞和訣竅」電子郵件的偏好設定。
特殊注意事項
- 僅限已驗證的使用者：您只能取得或更新已通過 API 呼叫驗證的使用者帳戶電子郵件偏好設定。您必須在要求路徑中指定這位使用者的電子郵件地址 (例如
user@email.com)，或使用me別名。 - 進階帳戶：如果您是進階帳戶使用者，系統會在進階帳戶層級設定電子郵件偏好設定，並套用至進階帳戶本身和所有子帳戶。使用 API 時，進階帳戶使用者應指定進階帳戶 ID，以便管理偏好設定。
- 服務帳戶：即使為服務帳戶設定電子郵件偏好設定，服務帳戶也不會收到通知。
UNCONFIRMED狀態：電子郵件偏好設定的UNCONFIRMED選擇加入狀態只能由伺服器設定。您無法使用 API 將偏好設定設為UNCONFIRMED。嘗試設定這項偏好設定會導致錯誤。UNCONFIRMED狀態表示系統已將確認電子郵件傳送給選擇加入的使用者，但對方尚未點選確認連結。
檢查 Merchant Center 電子郵件接收設定
如要查看特定 Merchant Center 帳戶目前的電子郵件通知設定，請使用 GetEmailPreferences 方法。你必須提供 Merchant Center 帳戶 ID，並使用使用者的電子郵件地址或 me 別名來指出已通過驗證的使用者。
這項要求會擷取 EmailPreferences 資源，顯示可用通知類別的啟用狀態，例如 news_and_tips。
GET https://merchantapi.googleapis.com/accounts/v1/accounts/{ACCOUNT_ID}/users/{EMAIL_ADDRESS}/emailPreferences
如果要求成功，系統會傳回 EmailPreferences 資源，顯示目前的設定。
範例回應：
{
"name": "accounts/{ACCOUNT_ID}/users/{EMAIL_ADDRESS}/emailPreferences",
"news_and_tips": "OPTED_IN"
}

變更 Merchant Center 電子郵件接收設定
如要變更電子郵件通知偏好設定 (例如選擇是否接收「新聞和提示」電子郵件)，請使用 UpdateEmailPreferences 方法。
在要求中，請提供 Merchant Center 帳戶 ID，並使用使用者電子郵件地址 (或 me 別名)。要求主體應包含 EmailPreferences 物件，並為 news_and_tips 欄位選取 opt_in_state。您也必須在 update_mask 查詢參數中指定 news_and_tips，指出要變更哪項偏好設定。
這項操作會更新指定 Merchant Center 帳戶中已驗證使用者的電子郵件偏好設定。舉例來說，將 news_and_tips 設為 OPTED_OUT，即可停止接收該帳戶的「新聞與提示」電子郵件。
PATCH https://merchantapi.googleapis.com/accounts/v1/accounts/{ACCOUNT_ID}/users/{EMAIL_ADDRESS}/emailPreferences?update_mask=news_and_tips
要求酬載範例 (選擇停用「新聞和提示」)：
{
"name": "accounts/{ACCOUNT_ID}/users/{EMAIL_ADDRESS}/emailPreferences",
"news_and_tips": "OPTED_OUT"
}
成功的要求會傳回更新後的 EmailPreferences 資源。
回應範例：
{
"name": "accounts/{ACCOUNT_ID}/users/{EMAIL_ADDRESS}/emailPreferences",
"news_and_tips": "OPTED_OUT"
}
