Token Validation Error

[nickmaina]

Literally spent more than 3 days just to call my first request after the hello world. Been getting

{'responseStatus': {'code': '9159', 'severity': 'ERROR', 'info': '', 'status': 401, 'message': 'Token validation failed'}} 

on CyberSource process payments endpoint.

Even tried to use SOAPUI but getting the 400 error.

{"responseStatus": {
   "code": "9501",
   "severity": "ERROR",
   "message": "Invalid input found, please correct the input data",
   "info": "",
   "status": "400"
}}

All this is just a copy paste from the api explorer.

My XPAY function

def x_pay_token(secret, resource_path, query_string, body=''):
    """Generates the XPayToken
    XPayToken = "xv2:"+ timestamp + ":" + SHA256HMAC(shared_secret, message)
    """
    if not isinstance(secret, bytes):
        secret = bytes(secret, encoding='utf8')

    timestamp = current_timestamp()
    
    # pre_hash_string = timestamp + resource_path + query_string + request_body
    pre_hash_string = (timestamp + resource_path +
                       query_string + body).rstrip().encode('utf-8')

    hash = hmac.new(secret, msg=pre_hash_string,
                    digestmod=hashlib.sha256).hexdigest()
    return 'xv2:' + timestamp + ':' + hash

The request data am passing

Hi, 

Thank you for your patience. Please use the following uri in the token generation: 

def URI = "v2/payments" instead of def URI = “cybersource/v2/payments”

Thank you, 

Vaibhav

This is now the response.

{
 "ID": null,
 "status": "500",
 "statusInformation": {
 "reason": "SYSTEM_ERROR",
 "message": "Request failed due to unknown system error."
 },
 "submitTimeUTC": "2018-02-21T08:12:34Z"
}

We even tried to use the github sample codes and just changed the api keys and secret in config file and it still fails.

Hi Nick, 

The recommendation is to change only the URI used for the token not the URI to which submit the request. 

Thank you,
