Creation of trigger application for SSG

What are the ways to create a trigger application for Supplementary Services Gateway (SSG)? I am aware of one way i.e. using HTML page. Is there any other way to do so?

You have to communicate through HTTP protocol with the SSG, so the HTML page of course not.

Thanks for your reply Kubig! Can you please throw some light on the ways in which a trigger application be created?

For example in Java or .Net

Can a trigger application communicate with SSG over https?
