網址擷取
這項服務可讓指令碼透過擷取網址，存取網路上的其他資源。指令碼可使用 UrlFetch 服務，發出 HTTP 和 HTTPS 要求，然後接收回應。UrlFetch 服務會使用 Google 的網路基礎架構，以提高效率和擴充服務。
使用這項服務提出的要求會來自特定的 IP 範圍集區。如需將這些要求加入許可清單或核准，您可以查看完整的 IP 位址清單。
UrlFetch 服務要求的預設使用者代理程式字串為 Mozilla/5.0 (compatible; Google-Apps-Script; beanserver; +https://script.google.com; id: SCRIPT_ID)。
這項服務需要 https://www.googleapis.com/auth/script.external_request 範圍。在大多數情況下，Apps Script 會自動偵測並納入指令碼所需的範圍，但如果您明確設定範圍，則必須手動新增此範圍才能使用 UrlFetchApp。
