Hello, I'm trying to do a monthly subscription with a setup fee where the setup fee is taken into account as the first payment and set the next payment whenever the trial period ends. I implemented it, to later realize that the subscription was successfully created even when the setup fee was not approved. How can i know that for a certain biliing subscription the setup fee was not successful... for I want to redirect the user to either a "try again" page or to an "approved" page. Right know if paypal sends me to the return url i take for granted there's a successful initial payment until know that i had my first case like this. Help would be greatly appreciated.
