Is it possible to tell PayPal through the NVP to not send a response to the IPN handler? For instance I use the IPN for payments I receive through a store I have running FoxyCart. However the store Im setting up now doesnt use a 3rd party cart, Im just using the API response to handle handle everything. Because of this I dont want PayPal to send a response to the IPN.
Ive scoped out the notify_url param, but that appears to only change where the IPN response is sent to.
I would prefer for this store that no IPN response gets sent at all, while allowing the other store to continue using the IPN it has always been.
Thanks in advance.
It depends on your account settings.
There are two types of IPN's, one is set at account level, and it's triggered whenever money comes into your account, regardless of the source. If you disable this, you will not get ny IPN's from either store.
The other type of IPN, is based on the API call being made. You need to check your magento payment module config to see if it's generating the second type, and disable it there. If it's already disabled, it means that you are only getting the first type of IPN. If this is the case, you would actually need to modify your OTHER shopping cart.
(A simpler option might be to open a child paypal account, rather than mess with all the carts)
