Clickthrough URL (Destination URL)

As per the IAB OpenRTB Dynamic Native Ads API Specification Version 1.2, section 5.1, always include the clickthrough URL (or destination URL) in the response.link object:

Field Required Type Description
link Yes Object

Destination Link. This is default link object for the ad. Individual assets can also have a link object which applies if the asset is activated (clicked). If the asset doesn’t have a link object, the parent link object applies.

Vungle Exchange also supports clickthrough URL (or destination URL) via Asset ID = '3' (CTA button URL). 
The clickthrough URL (or destination URL) passed via other assets, such as Image, App Icon, or App Title, will be ignored.

Open Measurement

When Open Measurement is available for a given bid request, Vungle Exchange will set imp.native.request.eventtrackers as {"event":555,"methods":[2]}.
