Google Apps Script interaction with Zoho API

I am experimenting with extracting certain data --Leads, Vendors, ...-- from Zoho CRM. Based on their API description I have created a function that creates a ticket and I have an issue with the next function that should obtain the data from Zoho.

I have added two Logger.log lines to visualize certain variables.

When I copy the zohoVendorUrl into a browser window I get to see the JSON data. When I run the script, the script shows null for the var o in the log.

When I read result.getResponseCode, the code is "200", which indicates the client sent a successful request.

Any suggestions on the "null" issue here?

// Get vendors from ZOHO CRM

function getVendors() {

ticket = getZohoTicket();

var zohoApiKey = " xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; //changed

var zohoVendorUrl = "https://crm.zoho.com/crm/ private/json/Leads/getRecords?&ticket=" + ticket +"&apikey=" + zohoApiKey + "&newFormat=1&selectColumns=All";

var result = UrlFetchApp.fetch( zohoVendorUrl);

var o = Utilities.jsonParse(result. getContentText());

Logger.log(o);

}

PS If I switch to http I am getting an Java exception error in GAS that it cannot open the URL.
