var sharedSecret = 'UJ8qGPUcz{H2gL1YPUMnaXUIJaMbVp2asi0U6w$3';

var postBody = '';

var timestamp = Math.floor(Date.now() / 1000);  

var preHashString = timestamp + resourcePath + queryParams + postBody;  

var hashString = CryptoJS.enc.Hex.stringify(CryptoJS.HmacSHA256(preHashString, sharedSecret));

var xPayToken = 'xv2:' + timestamp + ':' + hashString;

postman.setEnvironmentVariable('x-pay-token', xPayToken);
