Data nuances
- Meta serves daily ad insights for the last 37 months, counted back from today. Connecting earlier does not keep dates older than that window.
- SourceMedium reports Meta purchase conversions and revenue using the attribution setting on each ad set. Meta’s default for that setting is 7-day click, 1-day view. If you compare a different window in the Meta UI, the totals will not match.
- Ad performance also stores 1-day click, 7-day click, 28-day click, and 1-day view. The dashboard total uses the ad set setting, not those columns. To use one of those windows as the dashboard total, ask your account manager or integrations@sourcemedium.com. Meta removed the longer view-through windows from its API in January 2026, so only the one-day view window exists.
