encPaymentInstrument JWE Validation

I am sending enrollPAN payloads to VTS and getting ERROR results back.

 

message:{"errorResponse":{"status":400,"message":"Input for encPaymentInstrument is invalid or inconsistent with the profile.","reason":"invalidParameter","details":[{"location":"encPaymentInstrument"}]}}

 

 

Does this mean the "Decryption" at VTS has succeeded or not?

 

My current Payload is: [08:29:29 UTC - referenceid = "1529569752745652900" ]

"clientAppID":"Connekt","clientDeviceID":"823780937495628394529374","encPaymentInstrument":"eyJhbGciOiJBMjU2R0NNS1ciLCJpdiI6IlFldzZrZlltYlZzSnotLXkiLCJ0YWciOiJIcHhJalpDVTJaS3ZLSFZ3ZGVsNExBIiwia2lkIjoiVzVWMlNKTkpVQjI1U0lZVFgzWVEyMV96bkd6MkZ1UGpuYXBneGh3eUJWMDBjRWhkOCIsImNoYW5uZWxTZWN1cml0eUNvbnRleHQiOiJTSEFSRURfU0VDUkVUIiwiZW5jIjoiQTI1NkdDTSIsImlhdCI6IjE1Mjk1NzAyNDkwMDAifQ.AfSWKL75oD43R_EZ.UWV3NmtmWW1iVnNKei0teQ.q8O8QjTtGeY1gFxpTZr9MHN6bvj8Mb-JoJSfvsBxoSdc4zKFoiXGdTw7ZMIx_5heVwLWwMscz6WphOKBQh2xJ6dUi7q7fqFSccUkPjUT6lAT_YzCSlYxrt6Yit3kF8EkJKB-VIT8hr5DdeKqpqb2YIqJop_QH-BaVrOOSTzaa1eHDq8AfD0nNunySfxU1fQPPoiPyBPKGZH6yY3WOFxmhTzFZRI9yBRMyxkENavUgS5OwBRtKZ4Aa-lylxc_F6rex4bBFD5fcMcGzE3usyMgjHt4IIGKYjQowVwWIxHcaOefDzQAtw5kSOsNm8262tPklshRigA5HrMAbcvL8L4yUXQ0BzCWFQe2lq0iZ0gshk5V_SlTDaFlwI1M0Bpcvy84GwXV.iiKa4CeLtTfkgyKRaTDOXQ","locale":"en_US","panSource":"ISSUER_PUSH_PROVISION","platformType":"ANDROID"}

 

Has anyone have any test vectors to test the construction of the JWE, including the encryption algorithm inputs?

 

inputs: "all inputs" to have a reproducable correct payload.

e.g. iat, kid, shared_secret, the random generated cek, iv, and the JSON encPaymentInstrument in clear text, etc.

 

expected output: the body of the http web call e.g. JWE JSON payload.

Re: encPaymentInstrument JWE Validation

Hi @constvar,

 

To follow up, the 400 error means the PAN entered was invalid, the device used was invalid, or the PAN was not enrolled. Token Services support isn't widely distributed. More integration assistance would be given to priority merchants depending on their annual sales level if they contact developer@visa.com.

 

When contacting developer@visa.com, please make sure to reference this community forum post query.

 

 




Thanks,

Re: encPaymentInstrument JWE Validation

It was an encryption error, my JWE implementation was incorrect.

After solving the JWE encryption problem, I received a different error related to a field inside the encPaymenIntrument,

indicating that the decryption has succeeded.

Hi,

I saw that you have sorted out JWE decryption and can you please share some piece of code in GitHub or Somewhere then it will be very helpful for me and others who is struggling to get it done.

Hey @Raveen,

 

To further investigate, please provide the following information:

1. End Point
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.

 




Thanks,

Tee
