VAST/DAAST configuration

VAST (Video Ad Serving Template) is the most popular standard for exchanging information about ads. Although initially it was prepared for video this standard has also been adopted for audio commercials.

DAAST (Digital Audio Ad Serving Template) is a format very similar to VAST but specialized to audio ads.

AdTonos supports both formats.

* Parameter / header is not required in case the VAST request comes directly from the listener’s browser or mobile application. The parameter / header is required when the VAST tag is used in the Server-to-Server approach.

** The ip, lang and userAgent parameters or the X-Forwarded-For, X-Device-AcceptLanguage and X-Device-User-Agent headers are not required when the VAST request comes directly from the listener’s browser. If the VAST tag is used in a Server-to-Server approach, it is required to pass a pair of parameters or a pair of headers.

DAAST tag

DAAST tag uses the same parameters as VAST tag.

https://play.adtonos.com/xml/<stationId>/daast.xml?&listenerId=<listenerId>&sessio
nId=<sessionId>&ver=4.0&adType=preroll&contentType=audio&targeting=on&cb=<random>

Macros

Impressions and tracking events may contain macros – for example http://example.com?bb=[CACHEBUSTING].

AdTonos support the most popular VAST 4.x macros:
[CACHEBUSTING]
[TIMESTAMP]
[ASSETURI]
[PODSEQUENCE] with alias [ABPOS]
[ADCOUNT] with alias [COUNTER]
[PAGEURL] with alias [URL]

Requirements for Publisher:

  • Player that supports VAST or DAAST standard (e.g. OpenPlayer.js, Exo Player)
  • Configured ads.txt
  • For web player – JS tracking code
  • For mobile app – pass Advertising ID
  • Add VAST tag to your player

For VAST/DAAST integration Pre-roll & Mid-roll are available.

This kind of integration works quite simply under the condition your audio player is compatible with HTML5. If so, you just place generated links into the player playlist – it is the best idea to use VAST integration as a Pre-roll monetization. However some of the playout systems can send requests to the player in a defined airtime moment (like an ad break). Then a request from the playout system is passed further to us as a VAST request for ad.

We suggest using this type of integration for live radio.
