Hello,
I have another cart system in operation but I'd like to use gravity forms for donations. My understanding is that I am not necessarily required to enter http://monthlyreview.org/press/?page=gf_paypal_ipn
as my IPN URL in Paypal as long as gravity forms already sends this information (i.e. as part of a name-value pair).
The thing is I cannot change my current IPN settings because they are needed for my other cart but I much prefer gravity forms for donations. So my question is: if I just leave my current IPN alone will the Paypal add-on still work?
Thanks
