How to display Google Analytics' active visitors on site' number on my website?

Question

Google Analytics' new version has Real Time (beta), and it is able to show the number of active visitors on site.

I am wondering how to display this number on my website.

Answer 1

Right now you can't do that through the Google Analytics API but there is a feature request in for it.

Issue 154: Access to Real Time data

Update: Google has added a real time api: https://developers.google.com/analytics/devguides/reporting/realtime/v3/

Announcement

Update2: "The Google Analytics superProxy allows you to publicly share your Google Analytics reporting data."
