I know this is two questions:
1.) How can i get user donation billing address from Paypal to send them a Thank You? Do i have to ask in the GF before sending it to PayPal?
2.) How can i add custom info to the product info? I was a selection of different types of donation. in a couple of them we asked for "in honor" of. We want to have the name as a part of the PayPal invoice. Can we some combine two fields?
Thanks
