Apple Ads Attribution API

Measure and attribute app downloads that originate from Apple Search Ads campaigns

You can implement the API directly or with a third-party attribution solution to accurately measure the effectiveness of your advertising campaigns — while upholding Apple’s privacy principles. By adding just a few lines of code to your app, you can easily understand the value of different customer groups over time and, for search results campaigns, the keywords that drove their downloads. Then you can use the information to optimize your CPT and CPA targets for different audiences, ad groups, and search results keywords.

API requirements

Apps must be enabled with our attribution code to monitor attribution.

You can enable your app for attribution at any time to measure app downloads driven by Apple Search Ads campaigns. Attribution applies only to iOS customers who have tapped an ad and have downloaded the app within 30 days.

The Apple Ads Attribution API provides an attribution signal for all downloads you get from Apple Search Ads from devices using iOS 14.3 or later. Depending on each user’s privacy settings, either a standard or detailed attribution will be available. Note that attribution isn’t available for downloads from devices using iOS 14.2 or earlier.
