Visa Checkout Decryption Not Working

[dragthor]

Visa Checkout Integration Guide Version 19.01

In the above document I am unable to get the C# example code and the Node.js example code to successfully decrypt encPaymentData return by the Javascript modal.

Please verify the following:

"payload" means encPaymentData

"wrappedKey" means encKey

And when I call this function (in C#) - decryptPayload(String key, String wrappedKey, String payload), the "key" parameter is the "Shared Secret" underneath the "API Key" in the Visa Developer Portal, right?

Thanks.

In the node.js example - HMAC validation failure.

In the C# example - Padding is invalid and cannot be removed.

Done.  However, this forum is not that useful if a solution is not posted for others to see.

I am literally using the exact code examples for both node.js and C#.  Neither work for decrypting the encPaymentData payload.

Here is a public link to both the node.js and C# example code -

Why can't I see the "outbound and encryption" keys option/tab?
