How to make IFRAME-app VK parameters?

The task such - to write the application for selling tickets. An example of analog - radario, But sellers of tickets a lot, but the app I want to make one at all.

Is it possible when you run the application once in it somehow to pass a parameter (ID of the seller) ? Then the seller in Vkontakte will be able to post a link to the application ID parameter, and it directly when opened will show only the tickets. The question is, how ?
