At a glance: Enable Google to share the content of your SKAdNewtork (SKAN) app iOS postbacks with AppsFlyer.

Get SKAN postback data from Google Ads

If you work with multiple ad network partners, the best practice is to set it up in AppsFlyer. By doing so, SKAN performance metrics for all your ad network partners, enriched with other metrics like cost, are available via the AppsFlyer platform. 

Scope of SKAN reporting with Google Ads

  • Google Ads shares aggregated iOS SKAN postbacks they receive with AppsFlyer in the context of iOS app campaigns. These postbacks represent installs from multiple channels such as display, YouTube, and search.
  • AppsFlyer decodes the postback and then updates the SKAN dashboard and reports (including the postback raw data report).
  • iOS 14.5 implications on SRN reporting


On receipt of the iOS postback, Google determines the last click time using ad serving signals. However, AppsFlyer regards the click time as the install time. This can lead to differences between the AppsFlyer and Google dashboards.

Because of Google's click-reporting methodology and its retroactive data update on a daily basis, AppsFlyer pulls the data for the previous 45 days and displays the install under the last click before the install date.  For example, a click on July 1st can be reported to AppsFlyer until  August 15. AppsFlyer displays this install under the click date reported by Google. This impacts reports as follows: 

  • Aggregated reports and the dashboard update retroactively. 
  • Raw data reports don't change retroactively. Data (provided via Data Locker) is provided in folders according to the date Google provided the data to AppsFlyer (data arrival date).

Measurement and timing differences between AppsFlyer and Google Ads

Item Details 
Earliest data availability

Data is available starting on the date that you enable the integration according to the UTC time. Because Google uses the click time, installs from before the starting date can display retroactively. 

Install date 

Google sets the install time to the estimated last click time before the install. It is Google that determines the click time using ad serving signals.

The following should be considered when comparing media sources and the dashboard in AppsFlyer: 

  • AppsFlyer doesn't consider the app time zone or the Google Ads ad account time zone.
  • Google can report installs retroactively for 45 days after the install date.
  • In the case of other media sources, we derive the install time using the postback arrival time. 

From Google Ads API V10+, AppsFlyer only displays installs from postbacks with the did_win=TRUE. As a result, the installs number in AppsFlyer may be lower than in the Google Ads dashboard.

Troubleshooting and FAQ

Item Details 

Sending events to Google Ads

Q: Does it make sense to send additional event postbacks to Google Ads for events not selected in the conversion value measurement option?

A: For consenting users, send the full range of events to maximize Google Ads' ability to optimize.

Map multiple events to the same Google Ads event

Q: Can I map multiple in-app events to one Google Ads event?

A: If multiple events are mapped to one Google Ads standard event, Google Ads can't differentiate between the events. So, Google Ads will optimize toward the one event they recognize.

Campaign types supported

Q: What types of Google Ads campaigns are supported?

A: Web-to-app and App-to-app iOS campaigns including search, video, and so on. 

No data to pull

Q: Why does the connection status display "No data to pull: Check your Google data-sharing permissions"?

A: Either there is no SKAN data yet or you need to log into Google Ads using an Administrator user role on the account.
