Meta Marketing API Update Shifts to Views Metric
The Meta Marketing API update brings major changes for advertisers. The company will align its API with its new focus on views. This shift affects performance tracking across platforms. Earlier, Meta moved away from metrics like impressions and reach. Instead, it made views the main measurement for content. Now, it will apply that same rule to its developer tools.
June 2026, Meta will introduce a Page
Viewer metric in the Graph API. This metric will replace legacy reach data. As a result, marketers will see more consistent reporting across Facebook and Instagram. Meta will also remove Post Reach, Video Impressions, and Story Impressions from the API. These metrics already disappeared from Insights tools. Therefore, the update ensures full alignment across systems. Changes to Advantage+ and Automation. In addition, Meta will phase out older access points for Advantage+ campaigns.
Developers must migrate to the new Automation Unification setup.
This process began with version 25.0 in February 2025. After May 19, 2026, advertisers cannot create or update certain Advantage+ campaigns through older API versions. Consequently, third-party platforms must adopt the latest AI-powered tools. Meta says these updates will reduce confusion. The company also wants advertisers to use its newest automation features.
Although the changes seem technical, they matter for marketing teams. Anyone using external ad management tools should review the update. Staying aligned with Meta’s system will help maintain accurate reporting and campaign performance.
