Passing IPN, Silent Post and API Notifications to another application

[neutronron]

I have custom application that listens for notifications from Google Checkout, PayPal and Authorize.net using the API notification URL, IPN URL and Silent Post URL settings provided by each of the payment processors respectively.

I see in the Zen Cart documentation that this field has to be configured to post to Zen Cart (at least for PayPal Pro integration).

Can Zen Cart be configured to pass the notifications on to another URL?

Thanks

If you don't send the results back to Zen Cart the shopping cart will not be emptied and the order will not exist in ZC.

You can leave your PayPal settings set to send IPN notices to your existing custom application ... and that way it will continue to receive all notifications that originate from sources outside Zen Cart. Your Zen Cart site will directly receive the notifications for transactions originated via Zen Cart, in order to facilitate transaction processing.
