deep links in web client

[DrXero]

I'm developing an application that needs to be able to open a web browser and take the user directly to a particular contact or calendar appointment.

I've scoured the forums and documentation to find examples of direct URLs to do a few things:

 ?app=contacts 
 ?app=calendar 
 ?view=compose

What I need is something like:

 ?app=contacts&id=4323  (would pull up contact number 4323)

and

 ?app=calendar&view=appointment&id=634

Anybody know the magic query string? I'll be using this with a preauth key, which I've already got working just dandy.
