I want to send an HTTP request to some REST service from Google drive spreadsheet.
Is this possible?
Using Google Apps Script, you can make HTTP requests to external APIs from inside Google Docs/Sheets/etc. using the UrlFetchApp class:
var url = 'https://gdata.youtube.com/feeds/api/videos?'
+ 'q=skateboarding+dog'
+ '&start-index=21'
+ '&max-results=10'
+ '&v=2';
var response = UrlFetchApp.fetch(url);
Logger.log(response);
Note that:
This service requires the https://www.googleapis.com/auth/script.external_request scope. In most cases Apps Script automatically detects and includes the scopes a script needs, but if you are setting your scopes explicitly you must manually add this scope to use UrlFetchApp.
