Display & Video 360 API 第 3 版已停用。遷移至第 4 版。

指定目標

資源指定目標管理是 Display & Video 360 API 的核心功能。您可以為多種資源類型指派目標，並使用多種其他資源和 ID 空間。本頁詳細說明採用 Display & Video 360 API 指派目標對象選項服務時，應注意的限制和最佳做法。

使用指定目標繼承功能

部分資源的指定目標可由子項資源繼承。您可以擷取子項資源繼承的指定目標選項，但無法在子項資源層級編輯這些選項。這樣一來，品牌安全設定和其他指定目標就會在整個合作夥伴或廣告主中強制執行。

繼承路徑如下圖所示：

指定目標沿用圖表

如圖所示，部分指定目標層級僅支援部分指定目標類型。也就是說，部分指定目標選項無法在較高層級設定並沿用，而必須在較低層級設定。

YouTube 與合作夥伴資源的繼承功能

Display & Video 360 API 中的 YouTube 與合作夥伴資源不會反映指定目標的沿用設定。廣告群組繼承的指定目標無法在 AdGroup 層級擷取，且指派給父項資源的 YouTube 指定目標不會由子項資源繼承。

如要擷取廣告群組的所有功能指定目標設定，請擷取廣告群組、父項委刊項和父項廣告主的指定目標選項。

注意在建立委刊項時指派的指定目標

除了沿用的指定目標選項，大多數指定目標都只能在建立委刊項後指派。不過，有幾種指定目標類型會在建立委刊項時，為委刊項指派預設值子集。這些指定目標類型包括：

嘗試建立現有或刪除不存在的已指派指定目標選項會傳回錯誤，因此建議您在建立委刊項時，留意指派給委刊項的完整指定目標套件。如要擷取指派給委刊項的指定目標 (跨指定類型)，請使用 advertisers.lineItems.bulkListAssignedTargetingOptions。

此外，如果資源未指派該類型的指定目標選項，系統會預設部分設定。舉例來說，如果資源未定義 TARGETING_TYPE_AUTHORIZED_SELLER_STATUS 目標選項，表示該資源使用「授權直接銷售商和經銷商」狀態。

無法修改 YouTube 與合作夥伴指定目標

您無法使用 Display & Video 360 API，更新 YouTube 與合作夥伴廣告活動的指定目標。

YouTube 與合作夥伴指定目標包含直接指派給 YouTube 與合作夥伴委刊項和廣告群組的所有指定目標，以及下列指定目標類型的任何指定目標：

TARGETING_TYPE_SESSION_POSITION
TARGETING_TYPE_YOUTUBE_CHANNEL
TARGETING_TYPE_YOUTUBE_VIDEO

您可以直接使用 Display & Video 360 使用者介面更新指定目標，或上傳結構化資料檔案。

使用單一選項指派指定目標對象

大多數指定類型的指定目標選項都是個別指派。目標對象群組指定目標不會遵循這個模組化慣例，而是會指派至單一可設定的目標對象群組指定目標詳細資料物件，列出放送廣告時要納入和排除的目標對象 ID。這個目標對象群組選項的 assignedTargetingOptionId 一經指派，一律為「audienceGroup」。

因此，如要變更目標對象群組指定目標，您必須先刪除現有目標對象群組的指定目標選項，然後建立新的目標對象群組指定目標選項，並進行所需變更。您可以使用 advertisers.lineItems.bulkEditAssignedTargetingOptions，在單一要求中完成這項操作。

以下舉例說明如何更新目標對象指定目標，以便積極指定其他 Google 目標對象：

Java

long lineItemId = line-item-id

    Arrays.asList(google-audience-id-to-add,...);

// Convert list of Google Audience IDs into list of settings.
for (Long googleAudienceId : addedGoogleAudienceIds) {
  newGoogleAudienceSettings.add(new GoogleAudienceTargetingSetting()
      .setGoogleAudienceId(googleAudienceId));
}

// Create relevant bulk edit request objects.
BulkEditLineItemAssignedTargetingOptionsRequest requestContent =
    new BulkEditLineItemAssignedTargetingOptionsRequest();

為指定目標選項淘汰做好準備

指定目標選項並非固定不變，有時會停用少數選項。指定目標選項淘汰後，不會影響委刊項的廣告放送。淘汰後，這些選項會從現有行項目取消指派，嘗試擷取或指派這些選項的要求會導致錯誤。

為避免發生這類錯誤，建議您定期檢查儲存的目標選項 ID。為節省配額，我們建議您快取常用 ID。不過，儲存 ID 可能會導致您未察覺指定目標選項已遭淘汰。因此，您應定期使用 targetingOptions.targetingTypes.get 擷取所有儲存的指定目標選項 ID，確認 Display & Video 360 仍支援這些 ID。

如要瞭解重大淘汰項目，請參閱「已公布的淘汰項目」頁面。

請勿同時發出更新同一明細項目的要求

如果使用多個並行要求，嘗試更新單一委刊項的設定或指定目標，系統會傳回錯誤。適用要求包括：

如要同時為單一廣告素材新增或移除多個已指派的指定目標選項，請使用單一 advertisers.lineItems.bulkEditAssignedTargetingOptions 要求。如要更新委刊項的設定和指定目標，請將 patch 或 bulkUpdate 要求和相關指定目標要求加入佇列，確保系統在第一個要求傳回回應前，不會傳送第二個要求。

指定目標 透過集合功能整理內容 你可以依據偏好儲存及分類內容。
