Easy to install
Installation is easy if you follow the steps in the comprehensive manual. You can download the
manual before purchase (see below).
Uses PHP which is already installed on most servers
Linklok Paypal requires PHP 4 or PHP 5. PHP is installed on nearly all Linux and Windows based
servers whether they are shared or dedicated.
Does not require MySQL or other database system
Linklok Paypal only requires PHP 4 or PHP 5. It does not require MySQL or other database systems.
Works with Paypal's Buy Now, Add to Cart and Donation buttons.
Linklok Paypal works with Paypal's Buy Now buttons, Add to Cart buttons or Donation buttons
which means that it should work with your existing buttons that you may already have on your site.
Linklok can deliver any number of products that you client adds to the Paypal shopping cart.
Verifies orders are genuine with Paypal before delivery
When called by IPN or PDT Linklok will verify orders with Paypal to ensure they are genuine before
displaying or emailing download links. Linklok also checks that the amount paid is at least that
defined for the product. These checks are important to stop hackers redirecting their own buttons
or modifying the prices in yours.
Displays download page after payment using PDT and Auto Return or the older post method
When your client returns to your site after paying they will see a download page containing the
link(s) for all the products ordered. By default Linklok uses a simple built in page but you can define
a custom template to be used which can then seamlessly match your site. You can disable the
download page if you prefer only to email links.
Sends download email using IPN (this is sent even if the buyer does not return to your site)
When your client competes the Paypal checkout they will be sent an email containing the link(s)
for all the products ordered (in addition to the download page). This email gets sent by IPN so
will be sent even if the buyer does not return to your site. By default Linklok uses a simple built in
email but you can define a custom template to be used if you prefer.
Download links expire after a fixed time or can be set to never expire
Download links generated by Linklok can have an expiry time set which can be from minutes up to
several years. They can also be set to never expire in which case they simply hide the location of
the file on your server.
Links can be locked to buyers IP address (needs button change)
As well as the expiry time set in download links Linklok can also IP lock them to the buyer. This
does require some small changes to your buy buttons though. In most cases time expiry is
sufficient anyway.
Nobody ever knows the actual server location of the download file - not even the purchaser!
The download links do not contain the location of the file on your server so there is no risk of the
link being decoded etc. This ensures that nobody can ever bypass Linklok and link directly to
your product files.
Links use MD5 hashing so they are tamper proof
Download links generated by Linklok use MD5 hashing to ensure they cannot be modified
in any way.
Supports unlimited products in the Paypal shopping cart
Your buyers can add any number of products to the Paypal shopping cart. Linklok will display and
email all of the required download links.
Supports multiple files per product (product bundles or combos)
Sometimes you may have products that contain multiple files. Linklok can handle these bundle
( or combos) with ease. If you sell music tracks (mp3's) then this is a great way to sell albums.
You client will buy one album product but receive download links for each track in the album.
Works with auction (eBay) products where allowed by eBay
Linklok Paypal can deliver download products from eBay listings. However please note that
Paypal have changed their policy about sales of digital products on eBay so this may not be
allowed in some cases.
Supports multiple currencies
Linklok Paypal supports any currency that Paypal can work with. These include USD, EUR, GBP,
AUD, JPY and others.
eCheck payments can be set for instant download or delayed until cleared
By default Linklok will accept check payments like any other and deliver the digital products
immediately after checkout. However if you prefer to wait until the check has cleared before
delivering the files then Linklok can do this. In this case Linklok will automatically email the
download links when the check funds clear your account (usually 4 working days later).
Download & email templates are fully customizable for seamless delivery of digital products
Download and email templates are fully customizable. You can generate the pages in your favourite html editor in the same way as the rest of your site and then use special template variables where you want order specific data to be inserted. For example !!!orderno!!! will insert the Paypal transaction id in the template. Templates can be HTML or PHP based allowing you to still use any web stats code or affiliate code you may need.
Product specific download page and email templates can be assigned
For most sites one email and one download page template can handle all orders. However
Linklok does support product specific email and download page templates to be used.
Supports download resume and download managers
Linklok supports download resume and download managers wherever possible
Supports tangible products as well as downloads
Athough designed to sell digital products Linklok can also support tangible (physical) products
as well. There are several ways to handle this as described in the manual.
Can generate software unlock keys from files, a PHP function, Clicklocker or Software Passport
One of the many powerful features of Linklok is its ability to provide extra product data such as
unlock codes or serial numbers etc. These can be provided in advance in a text file list or
calculated using a user provided PHP function. Alternatively you can use Linklok to integrate
with
Clicklocker,
Acrolok or by using
Software Passport (Armadillo). We may also be able to help
integrate with other systems as well if required.
Can protect access to an html or PHP page instead of a download
Instead of pointing to a download Linklok links can also point to an html or PHP page. However
please note that the security only applies to the page pointed to and not onward links from that page.
Product specific template segment system
As well as supporting product specific templates Linklok also has a powerful product segments
system which enables templates to display differently for each product ordered.
Sell your Software Passport (Armadillo) protected software with Paypal as well as Digital River
If you use
Software Passport (Armadillo) to protect your software you can now sell via Paypal and
not just using Digital River. This is because Linklok can be used to generate the unlock keys.
Allows secure links to be emailed manually as well if necessary
You can use the manual order form feature of Linklok to email download links to anybody at
anytime without an order being processed.
Can send customised emails for order notification, order confirmation and download notification
In addition to the download email that is sent out you can also define emails to be sent to the
client for order confirmation and to you for order notification. Also you can also define an email
to be sent to you whenever a Linklok generated download link is used.
Integrates with Sitelok, our members area script

members area automatically. You can do this on a product basis which is useful either if you
