Ad Decision Server (ADS) response

The ADS response must contain one valid tracking event. At minimum, the tracking event can be an Impression tracking event. The tracking event should contain at least one NonLinear ad. This ad is the overlay ad, taking the form of a static, HTML, or iFrame resource.

<vmap AdBreak breaktype="linear" breakId="csoverlay"

If the VAST response is a VMAP with breakType of nonlinear, the avail metadata is inside the nonLinearAvails root object. If the VAST response is a VMAP with a breakType of linear, or is a plain VAST response without VMAP, the avail metadata is inside the avails root object.

The following VAST response is a wrapped VMAP response with a breakType value of linear.

In addition to the wrapped VMAP response, MediaTailor also supports a wrapped VMAP response with a breakType value of nonlinear, and a plain VAST response.
