Release Date: January 13th, 2026

The Inventory Availability Tool has been updated to improve flexibility, clarity, and alignment with how inventory is planned and evaluated. These updates introduce new setup options, streamline existing selections, and enhance how inventory types are defined.

In the setup section, users can now choose how inventory availability is defined:

• User Defined: Create custom targeting using deals, exchanges, geographies, livestream, apps, device types, channels, and more. The Inventory Discovery feature is available when this option is selected.
• Existing Line: Select an Advertiser, Campaign, and Line to inherit targeting and audience configurations from an existing line. Inventory Discovery is not available for this option, but users can adjust targeting parameters and audiences as needed.
• Inventory Type: In App, Web, Combined
• Creative Type: Audio, Banner, Video
