App Lists are used to group App Bundles for targeting across Campaigns and Lines. An App Bundle is the unique application identifier passed in the bid request and can be used to allow or block specific apps from serving. Once created, an App List can be reused across multiple Campaigns and Lines.

Create Custom App Lists:

1. Navigate to the Inventory tab.
2. Select New App List.
3. Name the new App List.
4. Enter each App Bundle on a new line in the following format:
   • Line Format: App Bundle
   • Line Example: com.king.candycrushsaga
5. Once saved, the list will automatically appear under the Campaign and Line Targeting menu:
   • Dropdown List > Inventory > App Lists
   • The list can then be applied as an Allow List or Block List.
