Unified Ad Server Inventory Management Services APIs

Inventory is made up of Ad Units and Ad Unit Groups.  

  • Ad units represent monetizable inventory within web pages, mobile apps and video players. An ad unit defines specific inventory attributes such as size, creative types, and page location. Unified Ad Server generates an ad tag code that is used to uniquely identify the ad.

    Ad units are the basic components of your inventory and represent the ad spaces you are offering for sale. When you create an ad unit, you can specify size, video ad attributes, native ad attributes, and general details such as refresh rates and frequency caps.
  • Ad Unit Groups are similar ad units bundled together to create a logical collection of specific ad units, for example, the leaderboard across the top of all major hub pages.
