There are three ways to integrate OWA with your web site or application:

• javascript Tracker
• PHP API
• REST Web Service

If your application is written in PHP, you will want to take advantage of the PHP API to add OWA tracking to your application as it will avoid an extra http request that must be made by the Javscript tracking method.

However, if your application is written in a programming language other than PHP, the Javascript API is probably your best bet.
