I just installed Fundraising and have been trying to set up

Hi.

I just installed Fundraising and have been trying to set up my IPN address in Paypal. The issue is I already have one set up for my webshop and it's seems that I can only have one. Could you advise what I should do? My current IPN is taylormation.co.uk/shop/ but I need one for the plugin that's http://www.taylormation.co.uk/wdf-payment-return/paypal/
Thank you. Jon.
