Meta API Overhaul Drops 7-Day & 28-Day View Attribution
Meta has recently announced a significant overhaul to its Ads Insights API, removing long-standing view-through attribution windows and tightening historical data access. The changes affect how advertisers measure conversions and how reporting tools retrieve performance data across Meta’s advertising ecosystem.
Key Developments
According to recent reports, Meta is updating its Ads Insights API to remove 7-day view and 28-day view attribution windows. These attribution settings will no longer return data once the changes take effect.
Meta is also deprecating several combined attribution windows, including configurations that mix click and view attribution. API requests relying on these deprecated windows may return empty or incomplete results.
At the same time, Meta is limiting how far back advertisers can access historical data for certain metrics and breakdowns. This includes tighter caps on hourly, frequency, and unique metric reporting.
Industry & Expert Context
Attribution measurement has been under sustained pressure following privacy-focused platform changes, particularly those affecting cross-device and post-view tracking. Meta previously reduced attribution windows as confidence in longer lookback periods declined.
Meta has stated that improvements in modeling and machine learning have enhanced reporting accuracy. Industry observers note that while longer click attribution may still be modeled internally, view-based attribution has become increasingly unreliable at scale.
Notably, Meta Ads Manager has already favored shorter click-based attribution windows for several years, bringing API reporting closer to the platform’s default UI behavior.
Why This Matters
For advertisers, the Meta API overhaul could lead to lower reported conversion volumes, especially for brands that relied heavily on view-through attribution.
Businesses with longer consideration cycles may see sharper reporting drops, even if actual performance remains unchanged. Automated dashboards, BI tools, and third-party connectors may also experience data gaps if deprecated fields are still in use.
The update reinforces a broader industry shift toward click-based and high-intent attribution models, prioritizing immediacy and measurable engagement.
What Happens Next
Going forward, advertisers and analytics teams will need to audit API-based reports and remove unsupported attribution windows. Re-benchmarking performance using shorter attribution windows will become essential for accurate trend analysis.
Data platforms and reporting tools are expected to align closely with Meta’s supported fields to maintain continuity. The changes also signal continued emphasis on privacy-safe measurement frameworks across major ad platforms.
FAQs: Meta API Attribution Changes
What attribution windows is Meta removing?
Meta is removing 7-day view and 28-day view attribution windows, along with certain combined click-and-view configurations.
Will this affect ad delivery?
Meta has stated these changes do not impact ad delivery, only how conversions are reported.
Why are reported conversions decreasing?
Shorter attribution windows naturally capture fewer conversions, especially those influenced by views rather than clicks.
Do older campaigns keep their attribution settings?
Campaigns created earlier retain their original attribution settings, but API access to deprecated windows will still be limited.
Final Takeaway
The Meta API overhaul marks a decisive shift away from long view-through attribution and toward streamlined, click-focused measurement. Advertisers should proactively update reporting workflows to avoid disruptions.
