Create VAST Config

In the tab “VAST” within the section "Configuration", you can create and manage your VAST configurations.

To create a new VAST configuration, click on "Add a VAST config" button and enter the configuration name.

Complete the various fields by referring to the OpenRTB 2.5 Imp.Video specs available here. Feel free to reach out to [e-mail] if you need assistance.

Callback options

After auctions have run, three scenarios can be adopted:

• No callback

Return either a VAST tag resulting from auctions or an empty VAST.

• VAST callback

Embed a VAST tag that will be called in case Nexx360 has no ad to serve. We provide macros to ensure GDPR items are transmitted:

Macros	Value
{GDPR}	0 or 1 if GDPR applies
{GDPR_CONSENT}	The GDPR consent string
{REFERRER_URL}	The url of the page where video is displayed
{CACHEBUSTER}	A unique id for the impression
{DESCRIPTION_URL}	Description URL

An example would be:

https://securepubads.g.doubleclick.net/gampad/ads?env=vp&gdfp_req=1&output=vast&iu=/1234/video-demo&sz=400x300&unviewed_position_start=1&ciu_szs=728x90,300x250&gdpr={GDPR}&gdpr_consent={GDPR_CONSENT}&url={REFERRER_URL}&cachebuster={CACHEBUSTER}

• Google Tag for GAM competition

Return a Google Tag enriched with Key Value targeting. It enables competition with orders in the adserver (direct, deals, ADX...).

We need to have a classic VAST tag available, example:

https://pubads.g.doubleclick.net/gampad/ads?iu=/1234/video-demo&description_url=&tfcd=0&npa=0&sz=640x480%7C1920x1080&gdfp_req=1&output=vast&unviewed_position_start=1&env=vp&impl=s&correlator=

For this option, Nexx360 requires a connection to your Google Ad Manager (GAM) account to push SSPs orders and line items. 👉🏼 More infos here.
