Paypal payment response without IPN listener? -


i'm adding simple membership renewal functionality web site using paypal payments standard buttons. have 300 or members, simple e-comm solution should work fine.

i'd capture sort of confirmation can capture on end can insert database. i've seen ipn listener method, seems more complex need - need pass confirmation code via url variable in return url, i.e. http://www.example.com/landing?transactionid=abc123. possible? also, there way pass own dynamic variable (for instance, membership id) form , have part of return string?

thanks

an alternative use express checkout 2 step process requiring pre-authorization , charging customer. if accepting echecks need use ipn update original transaction. can pass dynamic variable using custom field in paypal.

either way 1 of 2 methods required process transaction securely - stopping typing url suggesting?
