is there a way to create a FB app for a single page?

I want to create a FB app for a client's Facebook Page. How do I do this without开发者_JAVA百科 allowing other pages accessing it as well? Obviously I can do an ID check in my code, but I presume there's a 'proper' way of denying access to all and sundry?

There isn't a way to make an application private as in you're the only person that can install it but you could look into using the Static FBML box, you can have FBJS, FBML, CSS and HTML incorporated into that box and you'll be the only one able to use it.
