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);

Please let me know the issue

Hello, @saisandeep

Please see below information and follow.,

// Resource path for the API endpoint
var resourcePath = 'helloworld';

// Query parameters with the API key
var queryParams = 'apiKey=QM6BVPJH6XNA7RMZGLJG21iNon2ZUrYEA5CDL3sTmKb_-7Xzk';

// Shared secret provided by the API service
var sharedSecret = 'UJ8qGPUcz{H2gL1YPUMnaXUIJaMbVp2asi0U6w$3';

// Post body for the API call (if any)
var postBody = '';

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

// Concatenating the required elements for hashing
var preHashString = timestamp + resourcePath + queryParams + postBody;

// Generating the HMAC SHA256 hash of the pre-hash string
var hashString = CryptoJS.enc.Hex.stringify(CryptoJS.HmacSHA256(preHashString, sharedSecret));

// Creating the x-pay token
var xPayToken = 'xv2:' + timestamp + ':' + hashString;

// Setting the x-pay token in the environment variable
postman.setEnvironmentVariable('x-pay-token', xPayToken);

I hope my suggestion is helpful for you.

Best Regard,
