This service allows scripts to access other resources on the web by fetching URLs. A script can use the UrlFetch service to issue HTTP and HTTPS requests and receive responses. The UrlFetch service uses Google's network infrastructure for efficiency and scaling purposes.
Requests made using this service originate from a set pool of IP ranges. You can look up the full list of IP addresses if you need to whitelist or approve these requests.
This service requires the https://www.googleapis.com/auth/script.external_request
scope. In most cases Apps Script automatically detects and includes scopes a script needs, but
if you are
setting your scopes explicitly
you must manually add this scope to use Url
.
