The IPN way will cover some of what you mentioned above (response back from server), and a sort of server side post. With the IPN you can send form elements via cfhttp, which I think then goes to the Paypal website and then sends back a response to your IPN page (see easycfm.com for a description).
But with Paypal pro you can do everything server side (a bit of setting up but once done it is sweet), but the only problem is when we installed was you had to be an American business (with at least 90 days of credit history, we tried to do this 2 days after we registered the business name, and they said come back when you have some history).
With Paypal pro they also give you a testing sandbox to check transactions..
Hope that helps

I know a few people on here have set up paypal on websites. Just wondering if someone could answer a few questions for me.1 ) Is it a "Site > PayPal Server > Process Payment > Sent Response To Site > Give User Payment Response" sort of process?2 ) Can you just do server side posts to process payments?3 ) Do you actually get a response from the payment process?I am reading up on some stuff on the paypal site but these things would really give me a head startThanksSteve
