Hi,

This has increased recently, but our customers who pay through Auth.Net have had issues occasionally went processing their payment at the very end of the order.

It seems that after submitting the payment from the Auth.Net window, the payment will timeout on their end. Once it gets to us on the website orders, their auth code will show as "no ipn" and their transaction ID will be blank. The order itself will be unauthorized by this point too on our site, but the payment itself was approved on Auth.net. We end up having to fix the details and push it through manually for the customer.

I'm not too sure where to start with this, I will likely reach out to Auth.Net support as well to see if they have an idea as to why the payment might time out at the end of an order.

I don't think this is any form of fraud either, as the last two customers that dealt with this were shops that called to ask if their payment went through fine, to which this is how we found out their order timed out on their end. I haven't tried recreating any of their orders yet to see if we get the same issue, I may do so Monday.

Thanks,
Mike
