# MMP Update: View-through attribution support for Meta’s AEM

Source: https://tenjin.com/blog/mmp-update-view-through-attribution-support-for-metas-aem/

TL;DR Tenjin will support view-through attribution for Meta campaigns with enabled AEM starting from October 27th.


Tenjin’s integration with Meta continues to improve. In close collaboration, we’re adding view-through attribution for Meta campaigns that are eligible for Aggregated Events Measurement (AEM). The rollout of the update will begin on October 27th.


## What is Aggregated Events Measurement?


Meta’s [Aggregated Events Measurement](<https://www.facebook.com/business/help/721422165168355?id=1877298665783613>) is a protocol that allows for measurement of web and app events from people using iOS 14.5+ and later devices. AEM provides near real-time reporting to help make optimization decisions quicker and also more granular reporting insights.


## What do I need to do to enable view-through attribution for AEM campaigns?


To enable view-through attribution for AEM campaigns in Tenjin, make sure the Probabilistic Matching View-Through attribution window for your Meta channel is turned ON and set to 24 hours. This matches Meta’s default setting for AEM.


You can configure this by following our guide: [Attribution Window Setup](<https://docs.tenjin.com/docs/attribution-window-setup#app-ad-network-attribution-window>).
