I didn't know where to post this, but since this is a tool that can help me in selling my games, I posted it here. ^^

I want to know if anyone has used this, and if yes, then how to use it? I know how to enable the product using my PayPal account, I know how the buyer pays for a product (in this case, the game) etc., but what I couldn't find in the documentation, is how to allow the buyer to download the game immediately after paying, and so that it would be secure. I have a hunch it has something to do with Instant Payment Notification (IPN), but I'm not sure.
Any ideas?

think twice... if you allowe the user to download it automatically you'll have problems with fake paypal accounts and those who pay via their parents accounts. i've had this some times and the problem is that the jerk gets your game but you dont get the money.

i am handling it manually. i get an email from paypal.. check wether the money is there, or not and than i send an email to the customer with the download instruction. after the user downloaded it i disable the access.

I believe there was a secret variable of something included in the information PayPal sends to your website, so that you can check if a user really has paid and the money has reached your account. And the manual way is definitely not for me!
I know there is a possibility to do this automatically!!!

why not look into some open source shopping cart scripts?
zen cart for instance.

Hmm, what kind of payment options does zen-cart offer?? Couldn't find that information on their site.
But it looks promising, going to check it out later

Its been like 2 years since I've last used it but it definitely had a paypal payment module back then.

Just to toss this out to anyone looking for another alternative, we're using Plimus for our latest title, and had been using DigiBuy for seven years prior. Both are pretty good, and Plimus is popular among indie developers (I believe they even allow your customers to pay using PayPal).

I think you'll always get fraud orders, as Ello says, but if you're selling in any volume, then the time required to manually process orders would be more productively spent elsewhere (my opinion only :).

And that is why I need an automatic solution, because I don't know how much sales will I get. If they are a couple a day, then there wouldn't be any problems, but if I would have to look through 100 e-mails a day, that wouldn't make me a happy camper... ^^
Well, it seems that I have some good options here to look at, so I hope I will find what I need.

Thank you

I've used paypal for over a year and while my throughput is not great (a purchase or two a month), I've never had problem with payment or delivery.

Just make sure that the person that installs paypal on your site knows what they are doing (this is not DIY territory) and then do several test runs on your system: set up a 1 penny or 1 dollar item and buy and sell and deliver and go through the whole process a few times.

Also be sure to get the minimum you need. When you sign up to take payments by paypal, there is a whole bunch of options that can get expensive and we don't need (like telephone support).
