About Steven

I'm one of the web developers "I like Linux and play with cables"

I gained a degree in Physics from the University of Nottingham in 1994. Since then I've been a network analyst, programmed Windows based applications in DELPHI for financial institutions, developed and designed web applications in PHP and MySQL, and I'm also a strong advocate of open-source technology including the Linux based operating system Ubuntu, and web applications such as Joomla and Wordpress.

My tasks at Inmeres Solutions Ltd include the development of new web applications, development of components and plug-ins for existing open-source software, and maintenance of the internal networks.

PayPal Instant Payment Notifications (IPN)

Posted on by

Harnessing the simplicity and power of PayPal’s Instant Payment Notification system (or PayPal IPN for short) is a perfect solution to selling online downloads and subscription based content.

With their IPN system it is possible for PayPal to communicate information such as successful payments as well as the customer’s information during the payment process. At Inmeres we have solutions for bespoke systems or existing open-source systems such as OS Commerce, Zen Cart, or even WordPress.

Your knowledge is worth paying for, and through the combination of PayPal IPN, WordPress and a subscription based system you can sell this information. Either in the form of protected web pages or downloadable documents such as Adobe Acrobat PDFs.
