Clickbank Security Using PHP
(Page 1 out of 5)Here's a way to protect the products you sell with Clickbank, using their built-in protection and by implementing a 30-day expiration, all without having to worry about managing databases or customer lists.
The first step
First of all, Clickbank protection is decent as it is. If you want to keep your customers from passing the thank you page URL around to friends, there are a couple of things you can do.
Login to your Clickbank account: http://www.clickbank.com/login.html
At the top there's a link that says "Click HERE to modify your account". Click on the link.
On this page there are two links at the top, but one says "Click HERE to modify your account." Click on this one.
You should be at the page that allows you to edit the prices of all your Clickbank products. Scroll down to the bottom where it says:
Secret key (up to 16 letters & digits)
You should see a text box here. If it's empty, choose a secret key, type it in and remember it. It can be anything you want, but it should be different than your Clickbank password.
