Recurring payments IPN

Working on implementation of paypal's recurring payments, I've got encountered some problems. I have followed paypal's documentation from here: PayPal Express Checkout: Recurring Payments Process Flow

It seems that everything works properly and I get ProfileID at the end (from result of CreateRecurringPa开发者_如何学编程ymentsProfile() query). Recurring profile is also being created.

The problem is there's no IPN confirmation after running CreateRecurringPaymentsProfile() , but according to: PayPal Express Checkout: PayPal Notifications - it should be.

From my experience this happens only when IPN (Instant Payment Notifications) are not enabled in your merchant account. You can enable IPN in Profile > Instant Payment Notification Preferences.
