I'm building my IPN JSP and am trying to figure out when the txn_types happen... After looking through the docs this is how I think it works 1) Signup - A new user signs up. a) A subscr_signup is sent b) Several subscr_payment may be sent c) A subscr_failed maybe sent d) If a subscr_failed is sent, then a subscr_eot is sent 2) Cancelation - A user cancels his subscription. a) A subscr_cancel is sent immediately b) A subscr_eot is sent at the end of current term. 3) Modify - A user modifies his subscription. a) Several subscr_payments may be sent b) A subscr_failed maybe sent c) If a subscr_failed is sent, then a subscr_eot is sent 4) Payment - Regularly Scheduled a) Several subscr_payments may be sent 5) Failed Payment - After Retries a) A subscr_failed is sent b) A subscr_eot is sent 6) Normal EOT - If subscription expires a) A subscr_eot is sent If this is how everything works it would be safe to only worry about subscr_signup, subscr_modify, and subscr_eot.

Hi,
I would like to know if subscr_modify is sent immediately or when the modification take effect.
