Error from running SOAP UI example for X-PAY TOKEN

[petablue]

{"responseStatus":{"code":"9101","severity":"ERROR","info":"","status":401,"message":"Token validation failed"}}

I ran this code:

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
def hmac(String secretKey, String data) {
Mac mac = Mac.getInstance("HmacSHA256")
SecretKeySpec secretKeySpec = new SecretKeySpec(secretKey.getBytes(), "HmacSHA256")
mac.init(secretKeySpec)
byte[] digest = mac.doFinal(data.getBytes())
return digest
}
def APIKey = ‘VALUE_OF_YOUR_API_KEY’
def sharedSecret = ‘VALUE_OF_YOUR_SHARED_SECRET’
def URI = "helloworld"
def QS = "apikey="+APIKey
def timeStampUTC = String.valueOf(System.currentTimeMillis().intdiv(1000L))
def payload = ""
def HMACDigest = hmac(sharedSecret, timeStampUTC + URI + QS + payload)
def encodedDigest = HMACDigest.encodeHex().toString()
def XPayToken = "xv2:"+ timeStampUTC + ":" + encodedDigest
testRunner.testCase.setPropertyValue("xpayToken", XPayToken)
log.info(XPayToken)

I followed your instructions to the T and get this error. Please advice what I need to do.

(I only changed  APIKey and sharedSecret)

Hi @petablue,

I recommend using the VDC Playground tool to test X-Pay Token. You can find the guide on Getting Started with VDC Playground from this blog post here - https://developer.visa.com/pages/visa-developer-center-playground

Here's my setup for reference:

1. Select Auth Method as X-Pay Token.

2. Get the API Key and Shared Secret from VDP Dashboard  > Credentials section.

3. Provide the API key as part of query parameter on the API End Point.

4. Provide the Shared Secret in the settings input field.

Hope this helps.
