The Meta Marketing API update introduces technical changes that align Meta’s developer tools with its latest advertising measurement systems. Meta announced the Meta Marketing API update to ensure that external platforms use the same performance metrics now active in Meta Ads Manager and Insights. The changes affect developers, ad tech providers, and businesses that rely on API-based reporting.
Meta is shifting toward a unified “views” measurement model. Older engagement metrics are being removed as part of the update.
Measurement Changes in the Meta Marketing API Update
The Meta Marketing API update introduces a new Page Viewer metric in the Graph API. This metric is expected to roll out by the end of June 2026. It will replace several legacy reporting metrics.
Metrics being phased out include reach, video impressions, and story impressions. These measurements are no longer supported inside Meta’s internal reporting tools. The update ensures that API reporting reflects the same data standards.
Meta previously announced its move toward prioritizing views as the primary performance indicator. The API adjustments follow that earlier shift in reporting methodology.
Advantage+ Adjustments in the Meta Marketing API Update
The Meta Marketing API update also modifies support for Advantage+ campaigns. Legacy creation pathways for Advantage+ Shopping and Advantage+ App campaigns are being removed.
Starting with API version V25.0, older campaign creation methods were disabled on February 18, 2025. Full deprecation of these legacy pathways is scheduled for May 19, 2026. Advertisers using third-party integrations will automatically transition to the updated Advantage+ campaign structure.
Meta is also revising webhook permissions and removing outdated technical elements. These steps are intended to streamline developer access and reduce inconsistencies in campaign setup.
The Meta Marketing API update ensures that third-party tools rely on standardized metrics and modern campaign formats. The changes primarily impact developers and advertising platforms that integrate directly with Meta’s advertising systems.
