How to ask payment first, sign up after, with PayPal? I want user redirected to PayPal for a donation, then after payment with generated hash to special sign up page, this hash url sent to payment email as well. if user signs up it will match the hash , which will match the payment info. how to do that? and who can do that?
This is possible with aMember but will require small customization. You can use paypal infront of aMember, so user will pay and then amember will create an account automatically, but this will work only for products woith fixed amount (so this part should be customized)
