PaaS API version, fraud detection and credit card declines

[dmcheng]

We built a Visualforce online donation page with PaaS Class Library for a client early in 2013 last year and it was working fine until a couple days ago. The first problem was TransactionType was not specified, so I added that.


The second problem was that almost all credit cards were being declined, even the Visa 4111111111111111 number through my CnP developer account. The result code was Decline (5001).


I had to set Operation.DeclineFraud = false in order to get successful transactions, even with my developer CnP account.


Has the fraud detection sensitivity changed in the latest version? Is there a more specific error to distinguish fraud decline vs. other types of decline? Are there other settings we can use to keep fraud detection but avoid the decline problem?

thanks

Hi David,

There may be a number of factors. Please note that the test mode in a client account is different from your test account as a developer.

The TEST accounts given to you as a developer act like a live account and repeated attempts will block the attempts. If you give me the account number I can review your declines and find out the reasons.

It is best to whitelist your IP's or the emails used for testing by logging into the account Portal > Account Info > 3rd Party > Fraud and add the IP address or email address used for testing. Those parameters will be whitelisted.

Let us know the account number so we can review the declines.
