PDT & Hosted Paypal solution & Instant Payment Notification

As of 8th May 2011 Payment Data Transfer (PDT) does not currently work with the Hosted Sole Solution (HSS) product. PDT only works with Website Payments Standard transactions (the normal Buy Now, Add to Cart, Donation, and Subscription buttons).

You can use Instant Payment Notification (IPN) to receive a post of data after every transaction has occurred. That post would include buyer details like their e-mail address, name, and the transaction details. You wouldn't be able to use it to modify the return page your customer's get taken to since we cannot always guarantee the post will be there before the redirect happens - most of the times it does but it isn't unheard of to have IPN posts delayed.

You do however need PayPal PDT switched on if you are using the standard paypal account option on your website - that is if you want to us the TX return value as a means to validate the message back to your customer.
