Facebook Ads | Change in Lifetime Reach and Frequency Data
Beginning Tuesday, May 25, 2021, lifetime data for Reach and Frequency will no longer be available through the Facebook Ads API. Instead, Facebook will only provide the last 37 months worth of data.
For those affected datasets, no campaigns will be lost. If a campaign is older than 37 months and still continues to run, you will no longer have "lifetime" data, instead, data will be aggregated from the last 37 months.
