Encryption errors when testing Visa In-App Provisioning, Enroll Customer

[NCL-82]

I've been testing against sandbox Enroll Customer api

https://sandbox.api.visa.com/universal/core/customers?apikey=<redacted>

I'm encrypting data for the following fields:  encMobileNumber, encEmailAddress, and encAddress using MLE python code found here: https://developer.visa.com/pages/encryption_guide.

The x-pay-token seems to be getting validated correctly, however i'm getting an error back suggesting that the encryption itself may be invalid:

{'errorResponse': {'status': 400, 'reason': 'invalidParameter', 'message': 'Invalid input parameter(s)', 'details': [{'location': 'encMobileNumber', 'message': 'Failed to parse/decrypt the value provided.'}, {'location': 'encEmailAddress', 'message': 'Failed to parse/decrypt the value provided.'}, {'location': 'encAddress', 'message': 'Failed to parse/decrypt the value provided.'}]}}

I'm using the key id generated on my project dashboard along with the corresponding server encryption cert.

Request headers:

headers = {
    "content-type": "application/json",
    "X-PAY-TOKEN": <redacted>,
    "keyId": <redacted>
}

 
Any help would be appreciated, thanks

I'm having this same issue, and would appreciate any useful pointers.

Hi @tonietuk, @NCL-82,

Can you please share the x-correlation ID that is returned in the response header? Once we have the x-correlation ID, we'll be able to trace the error in our system and get back with an update. Thank you.

Hi,

The X-CORRELATION-ID for my latest request is: 1614280642_583_781887584_l73c015_VDP_WS

Thanks

Hi @NCL-82, @tonietuk,

Visa In-App Provisioning (VIAP) uses Field Level Encryption (FLE), not Message Level Encryption (MLE). Can you please send an email to developer@visa.com so we can provide further assistance on your VIAP implementation in sandbox? In your email, please share the follow information:

• Company legal name? 
• URL? 
• Your full name?
• Your role? 
• Your email address associated with the company? 
• What capabilities or functions will your application provide to your customers?  
• Use Case Information? 
• Who are your customers? 
• Which countries will your application be used in? 
• What will be your anticipated transaction volume for the first two years? 
• Do you have an existing relationship with Visa? If yes, can you provide the name of your Account Executive or other contact? 
• Are you a merchant, acquirer, issuer, or processor? 

Thanks!

I don't have a lot of the information you are requesting to hand, this is an investigation we are carrying out to see if we can get the visa integration working before going further.

Can you send me a link to any visa documentation on field level encryption? All I can find are docs for message level encryption...

Hi @NCL-82, @tonietuk,

Thank you for sharing the x-correlation ID. Please navigate here for the FLE being used in VIAP. In Sandbox, Visa will share the test keys that you can use for FLE. However we cannot share it in this public forum. Please do send us an email at developer@visa.com and provide some information about who you are and how you plan to use VIAP in your app. A VIAP product representative will then reach out to have an initial discussion before sharing the test keys. Thanks.
