建立及存取定期執行報表

您可以使用 Google Display &Video 360 UI 或 API 建立及定期產生報表。舉例來說，使用者可以設定顯示昨天曝光的每日報表，或顯示總支出的每月報表。

建立定期執行報表

在 Display &Video 360 報表介面或透過 queries.create API 方法建立新的排定報表。如要進一步瞭解 Display & Video 360 的報表功能和如何建立新報表，請參閱 Display & Video 360 支援網站。

您可以使用使用者介面中的 Repeats 欄位和 API 中的 schedule 欄位，安排建立報表的時間。這些欄位應設為適當的時間間隔。

完成適當的欄位設定後，這份報表就會安排在排定的時間執行，產生的報表也可供下載。

存取定期執行報表

排定的報表會產生簡單的 CSV 檔案，並自動安全地儲存在 Google Cloud Storage 中。不過，您無法直接存取含有這些檔案的 Google Cloud Storage 值區。因此，檔案可以透過 Display &Video 360 UI 手動下載，或透過 API 取得的預先授權網址透過程式輔助方式擷取。

以下示範如何使用 API 下載報表檔案。在此範例中，queries.reports.list 會與 orderBy 參數搭配使用，以在查詢下擷取最新的報表。接著，Report.reportMetadata.googleCloudStoragePath 欄位可用來找出報表檔案，並將其內容下載至本機 CSV 檔案。
