Here's how to quickly create a HTML snippet for your own website which shows the top entries from one of your Zendesk forums. You can use this for example to show your latest product updates on your homepage.
The widget code uses jQuery (and no server side code). An example page is attached which shows the latest posts on Zendesk Support's announcement forum.
var zendesk_url = 'https://support.zendesk.com';
var forum_id = 1;
var max_number_of_items = 4;
forum_id can be obtained from the URL of the forum.
