I’ve tested the credit card thing they’ve got and I have it working.

The only problem is, when I try to charge using an American Express, I  
get this “card\_code\_message”: “Issuer was not certified for card  
verification”.

Can anyone explain what this means, or if anyone else has had a problem  
like this?
