It's here

The point is that you have to know something about the incoming IPN POST request from PayPal before you can go back to the PayPal server and ask "Is this valid?"

So the synopsis example, where you just instantiate with no args, seems incorrect to me.

What am I missing? Is this one of those things where I don't get it because it's too simple?
