No, there's a separate thing they have such that every time <your paypal account> receives a payment, paypal's servers hit a page on your site (you tell them in a setting what page to use) and it sends a HTTP POST request to that page with a whole bunch of variables set that say how much money, what currency, who the sender was, what time/date etc etc etc.
I want to know what those variables are. That zend page had a really good page explaining each variable and the best way to interpret the data.
This is different from what you linked because the recurring payments API appears to be for recurring payments only, and is useless for one-time purchases/payments
