AudienceTargetingCondition specifies conditions for AudienceTargeting.
This condition object contains various filters on multiple dimensions of bid-request,
app, and user. Advertisers can selectively configure desired filters to form a
meaningful AudienceTarget condition collectively. The configured individual filters
must be satisfied unanimously in order for the resulting collective condition to be
satisfied.
Only filters with values will be effective. When a filter condition accepts
a list of values, i.e., list of countries for "allowed_countries", the filter
condition will be met when any match is found among the list.
String literals are case insensitive unless specified otherwise; i.e. "USA" and "usa"
equally represents the United States of America.
