Calling the CGI Script
The example below is an html form that will pass a software serial number and your ClickBank info on to the ClickBank CGI.
<form method="GET" action="http://www.clickbank.net/sell.cgi">
<p>Enter Your Serial Number : <p>
<input type="hidden" name="link" value="NickName/LinkNumber/LinkTitle">
<input type="text" name="seed" maxlength="16">
<input type="submit" value="Send">
</form>
The above form is very simple. It simply passes the serial number off as a value called seed and passes a hidden value called link. Seed will be used for the authentication sequence which will be described later. The value named link is the ClickBank data needed to process the order. This includes your ClickBank Nickname, you Link Number and your Link Title, respectively. The link number is your product number. If you have one product, then your link number is 1. The link title is the title you would like to appear in the ClickBank sales window. This should be your software name. Below is an example of a proper link:
YourClickBankNickName/1/The_Software_Title
The value 'seed' is the software serial number entered by the purchaser. It is also used to create an authentication code against the 16 digit key that you can specify from within your ClickBank account page. This works best if the software serial number is specific to every computer that it is installed on.
