Busca de URL
Esse serviço permite que scripts acessem outros recursos na Web ao buscar
URLs. Um script pode usar o serviço UrlFetch para emitir solicitações HTTP e HTTPS e
receber respostas. O serviço UrlFetch usa a infraestrutura de rede do Google para
efeitos de eficiência e escalonamento.
As solicitações feitas usando esse serviço têm origem em um conjunto de intervalos de IP. Consulte a lista completa de endereços IP
se você precisar adicionar essas solicitações à lista de permissões ou aprová-las.
A string de user agent padrão das solicitações de serviço do UrlFetch é
Mozilla/5.0 (compatible; Google-Apps-Script; beanserver; +https://script.google.com; id: SCRIPT_ID).
Este serviço requer o escopo
https://www.googleapis.com/auth/script.external_request. Na maioria dos casos, o Apps Script detecta e inclui automaticamente os escopos necessários para um script, mas, se você estiver definindo os escopos explicitamente, será necessário adicionar esse escopo manualmente para usar UrlFetchApp.
