Take the 2-minute tour ×  I have a recurring payment solution
set up via PayPal's IPN service, basically the user fills in a
form, pays the money and via IPN my system gets a ping to grand
the user access to the system.  Everything technically works
fine, but occasionally on the last day of a user's cycle they
forget that it is a recurring payment and complete the form
again. PayPal doesn't seem to mind this and creates a second
recurring payment profile.  Currently I go in, refund the money
and cancel this new payment profile, but obviously this isn't
ideal - is there any way I can configure PayPal to not accept
new profiles from people with currently active profiles? Or will
I need to catch this at my website's end and do some form of
lookup before allowing the payment?  share|improve this question
I think this has to happen at your end, cause I think Paypal
cant identify duplicate recurring payments. I think its just
Id's that get exchanged and a money ammount (plus the data what
comes further to mind) but
