Creating and Using VAST Zones
VAST zones are used when you want to display video advertising, either outstream, OTT or into your existing video content such as pre-roll, mid-roll, or post-roll ads.
The first thing you will need is a VAST Zone.
To create a VAST zone, click on the "Add New" button under your desired publisher, then choose "VAST Zone".
Next you'll want to assign any VAST campaigns that you've created, to this new VAST zone.
After you've assigned campaigns to your new VAST Zone, to get the VAST Tag that you will place into your video player, OTT player (such as Roku) or other platform that supports VAST, you will need to click the "Get Zone Link" button from the right hand side of the VAST Zone window.
