啟用委刊項

使用 Display & Video 360 API 建立的所有委刊項，一開始都是草稿狀態。在草稿狀態下，委刊項不會放送廣告，因此您可以自由調整設定和指定目標，而不會影響任何目前的廣告放送。本頁面說明確認產品線項目是否已準備好放送廣告的步驟，以及如何將其狀態更新為「有效」。

啟用前須知

由於委刊項是廣告收益透過廣告購買和放送的方式，因此請務必確保委刊項在啟用時能如預期放送廣告。請在啟用項目之前考量下列事項：

• 確認放送設定正確無誤：請檢查委刊項的 flight 欄位，確認委刊項的放送時間視窗設定正確無誤。委刊項的放送時段可以自訂，也可以沿用上層廣告訂單的放送時段。
• 確認沒有警告會阻止委刊項放送：使用 advertisers.lineItems.get 擷取委刊項資源，並檢查 warningMessages 欄位，確認委刊項沒有可能阻礙放送的警告。LineItemWarningMessage 列舉會指出每個警告的影響。
• 確認所有上層資源也處於有效狀態：如果上層廣告主、廣告活動或廣告訂單無效，有效的委刊項就不會開始放送廣告。使用廣告客戶、廣告活動和廣告訂單服務中的 GET 方法擷取這些資源。

啟用委刊項

如要啟用委刊項，請將其 entityStatus 欄位更新為 ENTITY_STATUS_ACTIVE。您可以使用 advertisers.lineItems.patch 方法更新個別委刊項的這個欄位，也可以使用 advertisers.lineItems.bulkUpdate 更新特定廣告主中的多個委刊項。

警告： 請勿同時提出 patch 或 bulkUpdate 要求，以及其他更新相同委刊項或其指定目標的要求。

以下範例說明如何使用 bulkUpdate 啟用多個委刊項：

Java

// Create the line item structure.
LineItem targetLineItem = new LineItem();
targetLineItem.setEntityStatus("ENTITY_STATUS_ACTIVE");

// Create the bulk update request body.
BulkUpdateLineItemsRequest requestBody = new BulkUpdateLineItemsRequest();
requestBody.setLineItemIds(line-item-ids);
requestBody.setTargetLineItem(targetLineItem);
requestBody.setUpdateMask("entityStatus");

// Configure the bulk update request.
LineItems.BulkUpdate request = service.advertisers().lineItems()
    .bulkUpdate(advertiser-id, requestBody);

// Update the line items.
BulkUpdateLineItemsResponse response = request.execute();

// Display the line items that were updated, failed, and skipped.
if (response.getUpdatedLineItemIds() != null) {
  System.out.printf(
      "The following line item IDs were successfully updated: %s.\n",
      Arrays.toString(response.getUpdatedLineItemIds().toArray()));
}
if (response.getFailedLineItemIds() != null) {
  System.out.printf("The following line item IDs failed to update: %s.\n",
      Arrays.toString(response.getFailedLineItemIds().toArray()));
  if (response.getErrors() != null) {
    System.out.printf(
        "The failed updates were caused by the following errors: %s.\n",
        Arrays.toString(response.getErrors().toArray()));
  }
}
if (response.getSkippedLineItemIds() != null) {
  System.out.printf(
      "The following line items IDs were skipped in the update: %s.\n",
      Arrays.toString(response.getSkippedLineItemIds().toArray()));
}

Python

# Create a line item object with only updated entity status.
line_item_obj = {
    'entityStatus': 'ENTITY_STATUS_ACTIVE'
}

# Build the bulk update request.
bulk_update_request = {
    'lineItemIds': line-item-ids,
    'targetLineItem': line_item_obj,
    'updateMask': "entityStatus"
}

# Update the line items.
response = service.advertisers().lineItems().bulkUpdate(
    advertiserId=advertiser-id,
    body=bulk_update_request
).execute()

# Display the line items that were updated, failed, and skipped.
if 'updatedLineItemIds' in response:
  print("The following line item IDs were updated: %s"
        % response['updatedLineItemIds'])
if 'failedLineItemIds' in response:
  print("The following line item IDs failed to update: %s"
        % response['failedLineItemIds'])
  if 'errors' in response:
    print("The failed updates were caused by the following errors:")
    for error in response["errors"]:
      print("Error code: %s, Message: %s" % (error["code"], error["message"]))
if 'skippedLineItemIds' in response:
  print("The following line items IDs were skipped in the update:: %s"
        % response['skippedLineItemIds'])

PHP

// Create request body.
$body = new Google_Service_DisplayVideo_BulkUpdateLineItemsRequest();
$body->setLineItemIds(line-item-ids);

// Create target line item with updated fields.
$lineItem = new Google_Service_DisplayVideo_LineItem();
$lineItem->setEntityStatus('ENTITY_STATUS_ACTIVE');
$body->setTargetLineItem($lineItem);

// Set update mask in request body.
$body->setUpdateMask("entityStatus");

// Call the API, updating the entity status for the identified line item.
$response = $service->advertisers_lineItems->bulkUpdate(
    advertiser-id,
    $body
);

// Display the line items that were updated, failed, and skipped.
if (!empty($response->getUpdatedLineItemIds())) {
    printf('The following line item IDs were updated:\n');
    foreach ($response->getUpdatedLineItemIds() as $id) {
        printf('%s\n', $id);
    }
}
if (!empty($response->getFailedLineItemIds())) {
    print('The following line item IDs failed to update:\n');
    foreach ($response->getFailedLineItemIds() as $id) {
        printf('%s\n', $id);
    }
    if (!empty($response->getErrors())) {
        print('The failed updates were caused by the following errors:\n');
        foreach ($response->getErrors() as $error) {
            printf(
                'Error Code: %s, Message: %s\n',
                $error->getCode(),
                $error->getMessage()
            );
        }
    }
}
if (!empty($response->getSkippedLineItemIds())) {
    print('The following line item IDs were skipped in the update:\n');
    foreach ($response->getSkippedLineItemIds() as $id) {
        printf('%s\n', $id);
    }
}
