I don't quite understand the syntax you give:  i.e.  GET /contacts/:contact_id

I can get the contacts, I have a contact_id, but can you give an example of how to pass the above argument?

When I get all the contacts, i pass something like this:

https://books.zoho.com/api/v3/contacts?authtoken=xxxxxxxxxxxxxxxx&organization_id=xxxxxxxxxx&page=1&filter_by=Status.Active&sort_column=contact_name

What is the syntax to request just a particular contact using the contact_id?

An example would be very helpful (I don't know what /contacts/:contact_id translates to)

Thanks!
