Paypal Integration

[markhad]

I am currently writing a Flash AS3 website where users upload file(s), I take payment, and when payment has been received, the files are emailed to me to be processed, all within the same SWF.

I can get the upload and email part all working nicely. My question is about the payment part. Ideally, I would like to use Paypal but the critical point is that payment and then confirmation must all be within the same SWF. If Paypal directs to another page and returns to a different URL (or the same one for that matter), the SWF would have ended which would be a problem for the emailing part.

Is there a solution for Paypal to take money within the same SWF and just allow further functions to run on confirmation?

I think Paypal Digital Goods might be the way to go, but any advcie would be garetfully receieved!

Thanks in advance.

Well, how else is the user supposed to securely enter their payment details if not on a page hosted by Paypal?

Hint: Any option that involves your page seeing the payment details is not secure.

Thank you for the reply. I do not fully understand but isn't paypal digital goods a sort of frame that is loaded within the swf?

You can not host a html page in Flash. That is a simple fact of life.

And from my quick research it looks like the PayPal solution you are trying to refer to is exactly that, a HTML page in an iframe.

ok, thanks. Will look at running a seperate SWF form the Paypal success page using a custom IPN field and mySQL to carry on from where I left off.

Paypal does have an API you can connect to from your server. So you can use a combo of flash and server-side scripting. The caveats are you have to have your website a sign certificate (https) and you'll have sign up with paypal's business plan.
