Linklok for Paypal IPN

Linklok for Paypal V1.98

As you probably know Paypal provides an easy to setup service for receiving payments for your products worldwide. One problem faced by many companies however is how to provide a secure way to deliver digital goods (software, eBooks, art etc) after a successful transaction. The Linklok Paypal system provides the solution and is custom written for use with Paypal.

After a successful purchase Paypal calls Linklok which will then verify the transaction (using the Paypal IPN system). If the transaction is verified Linklok will then display the download links for your products and also email them to the purchaser. These links do not show the true location of the file on your server so there is no way to bypass Linklok. Links can be set to expire between 1 minute and several years later if required (or never expire).

Demo
Unfortunately Paypal doesn't provide a way for us to perform a demo transaction (without charging you that is !). However we have setup a demo version that shows you what happens after a client successfully completes a Paypal transaction and allows you to receive the full Linklok Paypal manual. The real version performs order authentication with Paypal IPN which we obviously cannot do in this demo. Be sure to enter your real email address to receive the download link (and whitelist sales@vibralogix.com if necessary).
