Hi, I have a quick question, we have some customers using Vantiv Express hosted payments page for online transactions. These customers in question are movie theatres, so some people purchase tickets online in a couple batches. It seems that if they do that, the first one is fine, but a lot of times the bank will decline the next immediate transaction. This doesn't seem to occur with other processors we integrate with. Is there anything we can add to pass along to reduce these declines?
Thanks for your time.
Hello,
This is likely caused by our duplicate logic that is automatically enforced on all merchant accounts upon initial boarding. Our duplicate logic is: same transactionAmount, same cardNumber, same transaction category (sale, refund, etc.) within 25 transactions.
Now, to override or disable this feature, the following must be done programmatically in your calls to Express (in your case, within the TransactionSetup request):
1. Pass <DuplicateCheckDisableFlag> as 1/true
2. Pass <DuplciateOverrideFlag> as 1/true
For reference, detail around our duplicate logic and these fields in particular can be found on page 23 of our Express API.
