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). Linklok 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.
Vibralogix are the best.... Thanks to these guys my site is now fully automatic, I no longer need to send download links to clients. This has saved me hours each week! Linklok ipn is the best investment I have made! Keep up the good work.
Got the script installed and running ... Very cool, nicely designed, shockingly simple to set up. Thanks for a great product. I'd always wanted to be able to sell downloads of some of my writings, so this is exactly what I needed. Great documentation, too.
