> Make multiple, asynchronous API calls simultaneously using UrlFetchApp.fetchAll in Apps Script. mostly when running through a list of resources against which an API call needs to be triggered, we end up using the `UrlFetchApp`‘s [fetch](https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#fetchurl,-params) service; however, in case if the list is well-defined and needs to be consumed as a whole, you could make use of the [fetchall](https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#fetchallrequests) service instead.
