Linodeid for API - where do I find this

I've looked through the whole of the dashboard interface, but can't find the Linodeid that I would need in order to use the API e.g. to boot my linode, as required on this page: http://www.linode.com/api/linode/linode.boot

In the dashboard my linode is identified by a name rather than a number, yet the API seems to want a number.
