Works great. Any idea how to modify to work with queries?

This code:

function doRequest() {
  var service = getService();
  if (service.hasAccess()) {
    var url = 'https://quickbooks.api.intuit.com/v3/company/<myid...>';
    var url = url + '/query?query=select%20*%20from%20Account%20where%20Metadata.CreateTime%20>%20\'2014-12-31\'' + '&minorversion=63'
    var response = UrlFetchApp.fetch(url, {
      headers: {
        Authorization: 'Bearer ' + service.getAccessToken()
      }
    });
    var result = JSON.parse(response.getContentText());
    Logger.log(result)
    return result; //eats into json response, leaving only acct info
  } else {
    var authorizationUrl = service.getAuthorizationUrl();
    Logger.log('Open the following URL and re-run the script: %s', authorizationUrl);
    return "Authorize URL in logger";
  }
}

gives me this error:
Exception: Invalid argument: https://quickbooks.api.intuit.com/v3/company/123145927198904/query?query=select%20*%20from%20Account%20where%20Metadata.CreateTime%20>%20'2014-12-31'&minorversion=63

@Nightwielder1 may be its got with the encoding of the URL properly.
Example, when encoded correctly:
This:
https://quickbooks.api.intuit.com/v3/company/1234/query?query=SELECT FROM Customer WHERE Metadata.LastUpdatedTime > '2011-08-10T10:20:30-0700'

Becomes:
https://quickbooks.api.intuit.com/v3/company/1234/query?query=SELECT%20FROM%20Customer%20WHERE%20Metadata.LastUpdatedTime%20%3E+%272011-08-10T10%3A20%3A30-0700%27

You could try using an online encoder like this one: https://meyerweb.com/eric/tools/dencoder/

Hi, @goelp!
Thank you for the code, it's all working.
But when I'm trying to get some info from the QB it sends me the 403 error.
Basically, I have some problem with authorization, but I still can't find where might be the issue.

I use the code to get - as the @MotorCityCobra wrote:

function getInvoices() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('TEST');
var url = "https://quickbooks.api.intuit.com/v3/company/" + companyID + "/account?minorversion=65"

var headers = {
"muteHttpExceptions": true,
"headers": {
"Accept": "application/json",
"Content-Type": "application/json",
"Authorization": "Bearer " + getService().getAccessToken()
}
};

var response = UrlFetchApp.fetch(url, headers);
var data = JSON.parse(response.getContentText());
sheet.appendRow([JSON.stringify(data)]);
}

I've googled the error code - but I see that everything is correct with token, redirect link, scope...
this API blows my mind :-)

I keep getting this.
`Exception: Request failed for https://quickbooks.api.intuit.com returned code 404. Truncated server response:

... (use muteHttpExceptions option to examine full response)`
