Define Reach Data in Facebook Ads Custom API Connector
Define how to calculate reach data in the Facebook Ads custom API. Facebook uses user-level data to calculate reach. When a date or field is adjusted in Facebook, the granularity changes, and Facebook recalculates the reach value based on the new parameters. Processing historical reach data streams requires unique date ranges for each process. Set a unique reach value for each day based on the granularity. Every date must be processed separately to return the aggregated value for that date.
