I've got a connection to the cnpAPI sandbox via, and have been first playing with getting a response via the registerTokenRequest function.


I've come across multiple differing documents with examples of card numbers to use for testing features, and my issue that I seem to be running into is that no matter what number I put in for the card, the response always comes back as 801 - Account Number was successfully registered.

Does anyone have any tips on this?
