How to make a file accesible onlyl to the paypal button payment...

Hi all,
I have a paypal account and I have create buy button of it.
I want to insert the button in a website where after paying the users get access to download a file.
I have entered the url (for download..) when I made paypal button.
But , I want to be sure that the url must not accessed directly by putting the url in the browser by any third party or my self?
Does the paypal button itself ensure that its url (ater paying) maynot accessed otherwise?
Or should I have to insert some script for it?
thanks for your help.

I don't think that is possible.
If your paypal button is encrypted,others cannot find that url by looking at your code.
The customer will be redirected to your download url when they click on the "return to merchant" button after payment.

Thanks

 

there must be free too but dunno if they are trustworthy

 

You can also do that with http://www.e-junkie.com/ and i think they charge you $5/monthly and its a pretty solid system.

 

If I make the paypal button, then it hides the download url?Does the download url not seen in the browser?

 

f the code is encrypted then noo

 

Can I make the url not showing when making the paypal buttons?How?Thanks.
