autobuy api ?

[Gemster]

Hi, i need an autobuy api for my project but i have no idea where to start or where to find one :/

I have an auth system for .net projects, i need an auto buy to make a serial key and email it to the customers email or something like that.

Any ideas how this is done or where i can find one ?

Thanks for any help

By autobuy, you mean they can buy a key from you application, then be mailed a key?

I know Paypal has some things you can do to authorize payments, then once they are they can redirect them to a custom url.. You could then use a simple PHP script to generate/grab a key and email it.

i have a php that generates the license keys for either lifetime or x days.

I can create a simple php to send an email but its the autobuy with paypal part that i have no idea about and i meen no idea. I don't even know where to start with it but need it asap.

Thanks

The PayPal feature you're wanting is called "IPN" which stands for Instant Payment Notification. I'm currently working to get my own.

How are your PHP skills?

The example they have seems pretty straight forward... Once it comes back verified, run your code to generate the key and send the email.

my php skills are good, well, not beginner and to expert.

I just have no idea on how in implement the autobuy api :/

I keep getting confused on what you mean by autobuy... Is that another service? Or by autobuy do you mean you want them to be able to buy directly from your application?

I want people to buy my application. like when they buy it, they pay through paypal and once the payment has been made, they get a serial key emailed to them.

I have a site that generates the serial key too. it need 2 options, lifetime or 31 days(1 month)

Thanks
