T2A is an Application Programming Interface (API) providing fast, reliable and secure online transactional access to our data sets and validation services.

T2A is comprised of a number of methods which offer our services. These methods may be accessed from your website or application via XML, SOAP or JSON.

This documentation is intended to be used by software developers intending to use one or more of the T2A methods. We provide a simple XML/JSON interface, promising easy integration; we also provide code samples in some popular languages including PHP, "classic" ASP and JavaScript.
