I am having occasional problems where customers are checking out and making a typo that results in them getting a decline from authorize.net. They made a mistake in their billing address or the CVV or expiration. I’ve done it myself. When they reattempt with the correct information, I am getting a response from auth.net that “A duplicate transaction has been submitted.” and an order result of “Failed”. I reach out to Auth.net and they said it is a variable in my cart software that sets this. I have searched and seached on here, on google and in the code and cannot find it. Does anyone know where the setting is?
Version is 4.3.6 and yes, we use the built in auth/aim payment integration.
Was a solution for this ever found? I have a horrible problem on a very large site with this right now.
It is strange, because in the code I see that the system adds unique suffix (based on the current time) for each transaction
