Fail to post requests. "responseStatus":{"status":400,"code":&quot

[passiveradio]

Hello!

I'm new to VISA developer and trying to send requests to https://sandbox.api.visa.com/cofds-web/v1/datainfo to check whether the credit card is valid or not in Python.

Python code:

cert = 'C:\\Users\\user\\visa_cert\\cert.pem'

ca_cert = 'C:\\Users\\user\\visa_cert\\ca_cert.cer'

key = 'C:\\Users\\user\\visa_cert\\my_key.pem'

user_id = 'your user id of your project'

password = 'your password of your project'

timeout = 10

cred_info = 'credit_info.json'

payload = json.loads('''{

  "requestHeader": {

    "requestMessageId": "6da6b8b024532a2e0eacb1af58581",

    "messageDateTime": "2019-02-35 05:25:12.327"

  },

  "requestData": {

    "pANs": [

      4072208010000000

    ],

    "group": "STANDARD"

  }

}

''')

try:

    response = requests.post(url,

                            verify = (ca_cert),

                            cert=(cert, key),

                            # headers = headers,

                            auth=(user_id, password),

                            json = payload,

                            timeout=timeout

    )

except Exception as e:

    print(e)

Execution itself succeeded, but the response says the "Ecpectd input credential was not present"

Response header and contetns are as below.

response header:

{'Server': 'nginx', 'Date': 'Fri, 03 Jun 2022 13:52:17 GMT', 'Content-Type': 'application/json;charset=UTF-8', 'Content-Length': '130', 'Connection': 'keep-alive', 'X-SERVED-BY': 'c6795c5t4', 'X-CORRELATION-ID': '1654264337_872_241384137_c6795c5t4_VDP_WS', 'X-ERROR-ORIGIN': '9200', 'X-APP-STATUS': '400', 'X-Frame-Options':
'SAMEORIGIN', 'X-XSS-Protection': '0', 'X-Content-Type-Options': 'nosniff', 'Strict-Transport-Security': 'max-age=31536000;includeSubdomains', 'Cache-Control': 'no-cache, no-store, must-revalidate', 'Pragma': 'no-cache', 'Expires': '-1'}

response content:

b'{"responseStatus":{"status":400,"code":"9125","severity":"ERROR","message":"Expected input credential was not present","info":""}}'

I followed the instruction here(https://developer.visa.com/pages/working-with-visa-apis/two-way-ssl#configuring_a_twoway_ssl_keystor...) to generate the CA certificate, double-checked my user_id and password are correct and two-way SSL certificate is active.

I googled this error, but I'm still not sure how to fix this problem.

Thank you.

Hi @passiveradio,

I ran a sandbox test today and I received a successful request/response payload. Please see my sample payload below and try your test again. Please share your result with us and let us know if the error is fixed. Also, make sure that you enable the message level encryption.

Hi @passiveradio,

Is the error fixed?  

[passiveradio]

Hi! Diana,

Thank you for spending your time to address my problem.

Actually, I suppose the cause of my problem is the credential things, because the error is "Expected input credential was not present". The credentials I use are the latest generated ones, so I couldn't address why it says the input credential is not present.

Are there any steps I missed to conduct SSL connection between Visa server and my computer ?

Thank you,

Yudai

Hi @passiveradio, 

Please provide the information below:

1. Endpoint
2. Request Header
3. Request Body
4. Response Header (include the x-correlation-id)
5. Response Body

Using SoapUI, you can find the x-correlation-id in the Raw Tab of the response header.

Hi @passiveradio,

Please provide the information that I've asked of you in my prior post (above). Also, make sure to provide the x-correlation-id so that our engineering team can check the logs. If the error is fixed, let me know so that I can take you off my contact list. Thanks!

Hi @passiveradio,

This error usually occurs when the client certificate is not sent or if the credentials you used are invalid. Please check these two scenarios and get back to me on your result. If you're still experiencing an error, I'll log an incident to our engineering team for you.
