[web2py] Re: Paypal Digital Download

[howesc]

Andrew,

I use Paypal encrypted buttons from their web payments standard
product together with IPN on www.tenthrow.com to purchase and enable
digital download.  i have not looked closely at
http://web2pyslices.com/main/slices/take_slice/9 but this is probably
a nicely documented outline of how paypal with IPN works.

That said, i just saw paypal demo a host of cool stuff last week at
their developer conference.  you should check out the adaptive
payments API, and the inline payment processing flow - this presents
the user with the paypal checkout flow in a dialog without them
leaving your site.  while i have not integrated it yet, i think it
will build a superior user experience over the old buttons and
redirecting to paypal for checkout.

hopefully that helps some.  if you want more specifics about how i did
my integration with IPN let me know.

thanks,

christian
