Can I execute Google Apps Script code from a Chrome extension?

Question

I want to write a Chrome extension that allows users to send emails directly from the omnibox. Is it possible to directly execute Google Apps Script code, such as the Gmail Services API from within a Chrome extension?

Answer 1

Yes, you can but with some limitation If you publish your apps script code as a webapp which will be accessible publicly, you can make a GET request to the webapp URL to execute the Apps Script code.

e.g

doGet(e){
//use e.parameter here
//write your apps script code
return ContentService.createTextOutput('your return content');
}

after publishing it, say you got a URL like

https://script.google.com/macros/s/djihwerd98ejdeijded/exec

Now make a request from your chrome app

GET https://script.google.com/macros/s/djihwerd98ejdeijded/exec?param=value
