How it works
So assuming you already have an ebook like "How_to_make_money_with_Payza.pdf" uploaded to your server and want to be able to sell it to people on autopilot. You can do this by first going into your Payza account and creating a button.

Create the button
You just need to create a buy now button from within your Payza account, adding the details like Name, description, alert url, price and return urls.
The alert url is the url on your website where your payment notifications will be sent. It is the url where your payment handler is located so that it will be able to execute orders automatically.

Create your IPN handler
This is a web script that is stored on your server, precisely at your alert url and it can be a php, asp, perl or other active file that does work when it receives an input. Note that your ipn handler should compare your known security key with the security key auto-generated by any order from a Payza button. So it should only execute when the both passkeys are compared to be equals. You should go to your account and then to manage IPNs in order to generate your Security key and use that in creating your IPN handler. After creating your security key, you should test it with the IPN simulator in your account to see that it works. The IPN handler would also receive other variables such as the buyer's email and amount paid. Your IPN handler should then be able to use those variables to send email download links to everyone that purchases your item.

You can also test your buy button by going to Payza's sandbox page

Copy and paste your code
Working on creating your IPN handler is where the most work is but after that the next step is to just copy and paste your button code on your website's landing page. This is the page where you want potential buyers to go first before buying any ebook from you. The page should be attractive, easy to use and contain the Payza buy now button.

Test your sales page
After you've done all the work, you should test to see that it works and you can do this by going to your IPN setup and enabling test mode. Afterwards, you should revert to live mode.
