Enable App Aggregated Event Measurement Support

Enable Branch's support for Meta's App Aggregated Event Measurement

Overview

Meta's Aggregated Event Measurement (AEM) is a protocol that allows for the measurement of web and app events from people using iOS 14.5 and later devices. There are two levels of support:

Campaign TypeDescription
Mobile App EngagementAggregate Event Measurement is currently available for the following types of campaigns when the destination is set to a mobile app: sales campaigns with catalog turned on or off, lead campaigns, and engagement campaigns.
Mobile App InstallAggregated Event Measurement has expanded to include campaigns that use the app promotion objective. This means you can now run app promotion campaigns without configuring app events for Apple's SKAdNetwork, and more app events will be available for ad delivery optimization. You can continue to configure events for SKAdNetwork if you want to view performance across platforms.

App AEM will utilize the following aggregate identifiers instead of device IDs for iOS:

IdentifierDescription
campaign_idsA set of IDs found on some links that open the app from Facebook ads persisted for 7 days and forwarded to Facebook for campaign optimization. Required for Mobile App Engagement.
anon_idAn ID generated automatically by the Branch SDK persisted on install forwarded to Facebook for campaign optimization. Available for SDK v2.1.2+. Optional for Mobile App Engagement.

The new identifiers will be forwarded to Facebook through all conversion events for re-engagement campaign optimization.

FAQ

If an advertiser also uses the Facebook SDK for iOS, what should they do to enable App AEM?

If an advertiser uses both the Branch SDK and the Facebook SDK for iOS, they can pass the events in their app campaigns through either method. As a best practice ensure that the install and post-install events use the same preferred connection method by following the steps in the link below:

How is Branch integrating App AEM campaigns into reporting or exports?
