PayPal订阅和IPN

Question

After a PayPal subscription is created for a user, does subscr_signup get sent before or after confirming the payment?

I am using django-paypal , which does not have built-in functionality to handle the subscr_payment IPN message.

This lead me to wonder whether or not I can use subscr_signup as an indicator that the subscription was successful.

Many thanks

Typically subscr_signup is sent after subscr_payment(3 sec apart), but the sequence is not guaranteed. PayPal recommendation is to rely on subscr_signup. Read more here: http://www.mixedwaves.com/2010/11/paypal-subscriptions-ipn-demystified/
