appTargeting property
Targeting on a subset of app inventory.
If APP is listed in targeted_environments, the specified targeting is applied. A maximum of 30,000 app IDs can be targeted. An unset value for targeting allows all app-based bid requests to be sent. Apps can either be targeting positively (bid requests will be sent only if the destination app is listed in the targeting dimension) or negatively (bid requests will be sent only if the destination app is not listed in the targeting dimension).
Implementation
