Linklok Paypal IPN v1.8.null for instant and secure digital delivery

As you probably know Paypal provides an easy to setup service for receiving payments for your products worldwide. One problem faced by many sites however is how to securely automate delivery of digital products after payment. If you sell digital products such as music mp3’s, software, e-books, photographs, embroidery patterns or any other download file Linklok will automate the delivery process keeping your clients happy and making your life just that bit easier.
Seamless delivery with Paypal
The purchaser will click standard Paypal Buy Now, Add to Cart or Donation buttons and checkout through Paypal as normal (both Paypal accounts and credit card supported). Linkok will then immediately verify the payment with Paypal (checking the amount paid is correct) and return the user securely to the download page. Linklok also sends a download email out as well (this happens even if the buyer closes the browser before returning to your site!). The download links included in the download page and email do not show the location of your files on the server and will expire after a predefined time (you can even IP lock them if you wish). There is no way to break or modify the links as we use an MD5 hash to verify authenticity. Both the download page and the email are customizable so they can match exactly the style of your site providing a seamless delivery process. Linklok supports any number of products in the cart and also products that have multiple files (bundles). Linklok Paypal makes use of Paypal IPN, PDT and Auto Return features to provide security, reliability and ease of use.

Features
As well as allowing you to easily sell downloads Linklok Paypal has many advanced features including the ability to deliver unlock codes, serial numbers or other data with your download files. It can also integrate with affiliate systems and other applications.

Requirements
Linklok for Paypal works on most Linux or Windows servers whether shared or dedicated. Just check that the server has PHP 4 or PHP 5 installed (most do). We can recommend A2 Hosting for use with our scripts but most hosting plans are fine. We advise clients to download and read the manual (see above) before purchasing.
