Introducing lower confidence reach data in the Bid Manager API

Starting today, you can populate reports in the Bid Manager API with data that had been previously omitted due to lower statistical significance by using a new filter, FILTER_UNIQUE_REACH_SAMPLE_SIZE_ID, and setting the value to “0”.

This filter setting only impacts reach metrics with the following Metric prefixes as defined in the Bid Manager API:

• METRIC_UNIQUE_REACH_
• METRIC_VIRTUAL_PEOPLE_DUPLICATE_
• METRIC_VIRTUAL_PEOPLE_EXCLUSIVE_
• METRIC_VIRTUAL_PEOPLE_OVERLAP_

queries.create requests with queries that filter by FILTER_UNIQUE_REACH_SAMPLE_SIZE_ID but don’t include impacted metrics will return a 400 error.

On February 4, 2025, Display & Video 360 will include unique reach data with lower statistical confidence by default. If you want to ensure that your reports continue to only return high-confidence data, we recommend that you update your integration to use the new filter value to filter to "1" when creating reports with any of the impacted metrics.
