Duplicate Transaction Error

tromney — Wed, 02 May 2012 17:32:28 GMT

I have a shopping cart in which users can purchase products that are billed monthly, or billed at the time of the sale.

The problem that I am having is that when I have a recurring product that has the same price as a non-recurring product

I get a duplicate transaction error. I am sending two transactions to authorize.net. One is for the recurring product which is sent to the recurring card URL (ARB), and the other transaction is sent the the standard api url (AIM). Is there a way that I can prevent this?

Because ARB itself don't create any transaction until the scheduled date, most likely that you are doing AIM to test the CC# before a ARB. Either change the x_duplicate_window, or don't do AIM to test for ARB when the users is getting both at the same time.

But my scheduled date is the same day.

Is x_duplicate_window the only way around this?

ARB transaction only run on midnight.

Then yes, the only way around this is x_duplicate_window.
