Overview Mutual customers of Experian and Buyer Cloud can onboard their custom third-party segments and first-party segments for activation in Buyer Cloud using the Experian data feed. Register Experian Segments To share a segment across all accounts within a buzzkey, use the account ID “-1”. To register Experian segments within Buyer Cloud: Configure the file paths for the taxonomy as shown below, replacing the content in the chevrons with your information: s3://beeswax-data-us-east-1/segment-registry/taxonomy/experian/<buzzkey>/<accountid> Configure the file paths for the segment data as shown below, replacing the content in the chevrons with your information: s3://beeswax-data-us-east-1/user-list/experian/<buzzkey>/<accountId>/idtype/  After onboarding, the data will be available to the buzzkey and account ID provided in the S3 path within 12 hours.  Distribute taxonomy files before segment data files so the segment shell can be created before receiving data. Access Onboarded Segments After onboarding, your segments are in the Experian folder in Line Item Targeting.  Navigate to  Create Line Item  or  Edit Line Item  >  Targeting  >  Segments  >  Experian  folder, and select the subfolder named  Buzzkey/AccountID . Notes This integration is only available to US customers CPM charges are as defined in the taxonomy file, and the billing method does not change from the method used for your other third-party segments
