Last Updated: May 05, 2026

This method requires that you share your segment files with Index in one of the following ways:

  • If your segment files include a grouping of people-based IDs, IP addresses, URLs, or other supported match keys, you can send your segment files to Index using using Amazon S3 buckets. For more information about how this works, see Sending segment files to Index using Amazon S3 buckets.

  • If you want to match on main domain only, you can work with your Index Representative to upload these segment files using an API.

After Index has registered these values, these segments can be permissioned to accounts and targeted in deals. A deal activates and is sent to DSPs when Index receives ad requests that contain attributes that match a targeted segment's match key value.
