Why go through all of that trouble when PayPal has a developer center?
http://www.paypal.com/sdk/ (SDK's)

https://www.paypal.com/cgi-bin/webscr?cmd=p/pdn/intro-outside (Developer
Network)

https://www.paypal.com/cgi-bin/webscr?cmd=p/pdn/support-outside
(Developer Support)

https://developer.paypal.com/ (Developer Central)


You might want to check the source most of the time that you need
documentation or ask a question on their support forum.
