When using GravityForms with the PayPal extension, the plugin asks you to set your IPN in paypal to:

This is the settings page:
###The problems facing Paypal Multiple IPN are:
– You can only have one PayPal account because PayPal will terminate multiple accounts if you try to set them up
– PayPal only allows you to enter one IPN address on their website (admin)
###Potential Solutions are:
– Use the PayPal API to set the `notify_url` in your request
– Use a broadcast script to have a single IPN endpoint that will make CURL requests to all of your endpoints
– Ask your plugin developer to update the plugin you are using to use the `notify_url` instead of hard coding the IPN endpoint
