APISIGN_NOT_PROVIDED

[jatinmehta420]

Was using "https://bittrex.com/api/v1.1/account/getbalances?apikey=MY_API_KEY" through postman and got response "APISIGN_NOT_PROVIDED".
Where to get this "apisign" and also please tell from where to get "nonce" for appending with the API URL

I have calculated hash by following node.js file but still im getting same response "APISIGN_NOT_PROVIDED"
const crypto = require('crypto');
var url = 'https://bittrex.com/api/v1.1/account/getbalances?apikey=my_api_key&nonce=123456';
const hmac = crypto.createHmac('sha512', url,'my_secret_key');
console.log(${hmac.digest('hex')} );
