Hi,
You can do this through
ConstantDataService. The
getUserInterestCriterion() method of ConstantDataService, when filtered by IN_MARKET userInterestTaxonomyType, returns list of
CriterionUserInterests (in-market audiences). The returned CriterionUserInterest list include
userInterestId (which you can retrieve from the
Criteria field of the Audience Performance Report - eg.
92000 of a Criteria "uservertical: 92000") together with its equivalent name represented by the
userInterestName field.
You can refer
here for more information on how to determine criteria prefixes and acquire the information you need using them.
Best regards,
