Test American Express Card Verification
Before using CVN with American Express, it is strongly recommended that you follow these
steps:
- Contact customer support to have your account configured for CVN. Until you do this, you will receive a1in theccAuthReply_cvCoderesponse field.
- Test your system in production using a small currency amount, such as one currency unit. Instead of using the test account numbers, use a real payment card account number, and send an incorrect CVN in the request for authorization. The card should be refused and the request declined.
