Discrepancies Between AppsFlyer and Snapchat

  • Advertisers


In certain instances, advertisers can see fewer installs on AppsFlyer's dashboard than on Snapchat’s Ads Manager dashboard. Sometimes, the discrepancy can be addressed by making changes to the settings in the AppsFlyer dashboard or Snapchat Ads Manager (e.g timezone settings, attribution windows etc.). However, a discrepancy between the two dashboards is expected. Advertisers should rely on the AppsFlyer dashboard as the source of truth when evaluating CPI and performance.

Advertisers should be aware of the following causes and consider taking the necessary actions.

Source of Discrepancies and Solutions

Set out below are a number of causes of discrepancies and possible solutions.

Different Lookback Windows

By default, Snapchat Ads Manager and AppsFlyer have different attribution windows.

Lookback Window Snapchat Ads Manager AppsFlyer

Click Attribution Lookback Window

28 days

7 days by default (can be configured to be 1-30 days)

View-Through Attribution Lookback Window

1 day

1 day by default (can be configured to be 1-48 hours)


  1. Configure the attribution window in AppsFlyer to match Snapchat’s default values.
  2. Advertisers can select attribution windows in the Ads Manager dashboard to match what they have set as default in their attribution partner (MMP) dashboard. Contact your Snapchat CSM to have your account whitelisted to activate this feature.

Time Zone Differences

By default, Ads Manager uses PST timezone whereas AppsFlyer uses UTC +0 by default. As a result, for example, Snapchat might attribute an install to Friday while AppsFlyer attributes it to Saturday.

Multi-Channel Source Attribution

A user might engage with an ad for the same app on multiple platforms. When the user installs the app, multiple platforms may take credit for the install.

Snapchat Ads Manager counts each install occurring within the attribution window as an install attributed to Snapchat.

AppsFlyer applies last touch attribution. AppsFlyer only credits the last platform to show the user an ad with credit for the app install or action.

As a result, especially with very large multi-platform campaigns, a user can see ads on a number of platforms before installing. All ads have an impact on the users, but only the last platforms to show an ad receive credit from AppsFlyer. This can lead to discrepancies as high as 40% between AppsFlyer and Snapchat Ads Manager.


Snapchat is a just one mobile application, whereas other platforms own multiple mobile applications or mobile ad networks/exchanges. Due to their additional reach across multiple properties, it is possible that competitors might win the last touch, yet Snapchat is still driving significant value.

Ultimately, AppsFlyer should be the dashboard used to evaluate eCPI and performance. When there is a discrepancy, default to AppsFlyer as the source of truth. Keep in mind that to fully evaluate the impact of your Snapchat campaigns, you should work with AppsFlyer to keep a record of the volume of conversions where Snapchat was a contributor to the conversion, but was not the last touch. There is value to understanding this even if you attribute based on last touch.

To manage the discrepancy, advertisers should keep records of the approximate percentage of total conversions for which Snapchat was a contributor but not the last contributor and as such create a new eCPI goal for Snapchat based on this approximate delta.
