Are there any changes to IPN params with Enhanced Recurring Payments

I'm using Paypal Website Payments Standard to accept recurring payments, but thinking of upgrading to "Enhanced Recurring Payments" to accept recurring payments from people without paypal accounts. I want to know, what if any are the changes to the APIs? Specifically, do the IPN messages differ at all? I can't find any information on how Enhanced Recurring Payments changes it, if at all.

If anybody knows, or can post a sample IPN for an Enhanced Recurring Payment without a PayPal account, that would be great!

Solution

There is a difference of only one variable between the IPN for PayPal Payments and the Credit card Payments . For the credit IPN you will receive an extra variable "receipt_id" in addition to the other variables . I have posted the two sample IPN's below :
