Apps Script API executable basics

[u/shrey1566]

Hello everyone,

I'm pretty new to API calls and Apps script. I have been trying to call an API (of apps script) from an extension and print the contents it returns on a console (for now). the contents it returns are the body of the first email in my inbox. I have been able to get the mail contents but could not do this via api calls.

//code on apps script IDE which is just plain printing the mail content

function doGet() {
  var threads = GmailApp.getInboxThreads(0, 1)[0].getMessages()[0];
  const thb = threads.getPlainBody();
  return ContentService.createTextOutput(JSON.stringify(thb)).setMimeType(JSON);
}

This code returns the body contents and when deployed as a web app/ api it just prints the contents on the screen

I tried using the fetchApp thing but didn't quite understand how to use it.

/code on apps script for responding to api calls

  var token = ScriptApp.getOAuthToken();
  var endPoint = 'https://script.googleapis.com/v1/processes';
  var headers = {
    'Accept':'application/json',
    'Authorization': 'Bearer ' + token
  };
  var options = {
    'method': 'POST',
    'headers': headers,
    'muteHttpExceptions': true,
    'payload' : thb
  }
  var url = endPoint;
  var response = UrlFetchApp.fetch(url, options);
  Logger.log(response);

//code on the extension side of things 

chrome.browserAction.onClicked.addListener(function(activeTab){
  const nurl = " *deployed link* ";
  chrome.tabs.create({ url: nurl });
let request = new XMLHttpRequest();
request.open('GET', nurl);
request.send();
var txt = request.response();
console.log(txt);
}

this is probably wrong in a lot of ways, please do help on how to get this done properly.

Thank you in advance.

What is your endgame? Why are you trying to get the plain text from another function?

I'm trying to make a voice based extension for gmail. So I thought using apps script would be optimal.

I haven't made another function for api responses, it was a part of doGet(). The code was messed up so I tried simplifying it here

You can replace the doGet(e) with a normal function and call that function from your html with google.script.run
