That was helpful John! FYI, it seems your Google Checkout code is broken!

You don't need any third-party API's to talk to paypal. Since the paypal site accepts standard GET and POST CGI data, sending a transaction to Paypal can be done by setting up a LoadVars object, setting the parameters to your shopping cart in the object, then sending that LoadVars object to PayPal's little processor at https://www.paypal.com/cgi-bin/webscr (note that there's apparently a long-standing bug in Flash's POST-handler, so I just use GET. It makes for ugly URL's, but it works) As for doing back-end processing from Paypal (i.e. being notified that somebody bought something and you need to act on that purchase), google for "IPN", which is Paypal's spec for creating and acting on transactions. Paypal's got good sample code in several server-side languages along with developer forums and a sandbox (i.e. a "fake paypal" where you can test your code without spending real money). The process basically goes like this. . . 1. You send your shopping cart data to paypal (either from Flash or some other browser-based shopping-cart solution) 2. The user is sent to paypal where he pays for the transaction. 3. Paypal contacts some server-side code telling you that somebody bought something. 4. You verify the transaction with paypal (to make sure you're not being spoofed) 5. If verified, do whatever's necessary to complete the transaction, like email the user a download link. Here's my little shopping-cart. Note that it also talks to Google Checkout, which has a few more steps but is otherwise similar. http://www.thecodezone.com/buy.html ----- Original Message ---- From: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> To: [email protected] Sent: Monday, April 23, 2007 11:23:40 AM Subject: [Flashcoders] flash and paypal i'm going to be producing a site which sells some exclusive, single and multiple (ie shopping cart) products which i'd like to do in flash. the client wants to use paypal to begin with (it's a startup).
