Hi! Need help with xpay token generation foreignexchangerates (v2) api

this is the method implementation for xpay token key generation.

secret = bytes(shared_secret, 'utf-8')
timestamp = str(timegm(datetime.datetime.utcnow().timetuple()))
pre_hash_string = bytes(timestamp + resource_path + query_string + body, 'utf-8')
print(pre_hash_string)
hash_string = hmac.new(secret, pre_hash_string, digestmod=hashlib.sha256).hexdigest()
x_pay_token = 'xv2:' + timestamp + ':' + hash_string

 

Below are the parameters for xpay token generation:

api_key = 'Z93UKQ5PDYB2W5H2YRD621kyUNDazyuhSJqh7T-rTRU0zsRxM'
shared_secret = 'E3K0YZ5XFG}6RarTa{Og1X-M2l{PqVnim@xIFKoH'
timeout = 10
query_string = "apiKey=" + api_key
resource_path = "forexrates/v2/foreignexchangerates"
body ='''{
"acquirerDetails": {
"bin": 408999,
"settlement": {
"currencyCode": "840"
}
},
"rateProductCode": "A",
"markupRate": "0.07",
"destinationCurrencyCode": "826",
"sourceAmount": "100.55",
"sourceCurrencyCode": "840"
}'''
Given below is post request:
 
databody = {
"acquirerDetails": {
"bin": 408999,
"settlement": {
"currencyCode": "840"
}
},
"rateProductCode": "A",
"markupRate": "0.07",
"destinationCurrencyCode": "826",
"sourceAmount": "100.55",
"sourceCurrencyCode": "840"
}
headers = {'x-pay-token': x_pay_token, 'accept':'application/json'}
response = requests.post(url + '?' + query_string,
headers=headers,
timeout=timeout,
data=databody
)
And this is the output:
 
{'responseStatus': {'status': 401, 'code': '9159', 'severity': 'ERROR', 'message': 'Token Validation Failed', 'info': ''}}

Thanks Diana for the reply. But it seems you ain't using x-pay-token (where I'm currently stuck at!)

Hi @sakshi,

 

I did not use x-pay token. I used two-way SSL. The Foreign Exchange Rates authentication method is two-way SSL. Please use two-way SSL, test again and share your result with us. Here's the page link to the FX Rates authentication method: https://developer.visa.com/capabilities/foreign_exchange/docs-authentication  




Thanks,

Diana
