I added NOTIFYURL parameter in your function formatDoDirectPaymentNvps() but paypal do not return to the mentioned url. This is in case of sandbox testing. Also how can I rely on session data, if computer get crashed after I made an request. Can we get parameters like sessionId passed from the website and notifyurl returns data in there.
