在 Google Ads API 中，您可以要求有效的作業提交，而失敗的作業則會傳回錯誤。這項功能稱為「部分失敗」，可讓您在最後分別處理失敗的作業。這項屬性可用於許多 Google Ads API 服務的非 get 方法。
技術詳細資料
如要使用這項功能，請設定您要使用的 partialFailure 方法參數。每個用戶端程式庫的名稱可能略有不同。舉例來說，如要使用 MutateAdGroups 傳送要求時啟用這項功能，請執行下列操作：
Java
mutateAdGroups(String.valueOf(customerId), operations, true)
C#
MutateAdGroups(customerId.ToString(), operations, true, false)
PHP
mutateAdGroups($customerId, $operations, ['partialFailure' => true])
Python
mutate_ad_groups(customer_id, operations, partial_failure=True)
小茹
mutate_ad_groups(customer_id, operations, partial_failure: true)
Perl
mutate({customerId => $customer_id, operations => $operations, partialFailure => 'true'})
服務會執行沒有錯誤的作業。系統會針對成功的作業傳回結果，針對失敗的作業傳回錯誤。
用量
假設您需要在帳戶中新增一組廣告群組，但部分廣告群組可能會發生問題。您想建立有效的廣告群組，但已傳回失敗的廣告群組，以及相關錯誤。

處理成功和失敗的作業
如果對應於提交作業的結果成功，其訊息會包含資源名稱。在這種情況下，您可以直接列印資訊，或將資訊用於其他用途。
不過，如果結果沒有任何內容，表示對應的作業已失敗。您可以從回應的 partial_failure_error 開始，擷取錯誤詳細資料：
partial_failure_error欄位的類型為Status，其中包含詳細資料清單。- 每個詳細資料都對應至每個提交的作業。代表
GoogleAdsFailure的例項。 GoogleAdsFailure包含GoogleAdsError物件的清單。因此，一個提交的作業可能包含許多錯誤。GoogleAdsError會顯示錯誤訊息、錯誤代碼和所有其他相關詳細資料。
所有用戶端程式庫都提供實用函式，可為您擷取這些錯誤詳細資料，因此您不必擔心要從頭執行上述步驟。請參考下方的程式碼片段：
