To set up attribution postbacks for AppsFlyer, add your Chartboost app ID and app signature to the AppsFlyer dashboard under Chartboost S2S.

Toggle the Activate Partner switch. This setting activates both attribution and postbacks. Accordingly, turning off this switch will immediately halt postbacks and reporting of new installs and events in the Partner Dashboard.

Below you'll find an example of the minimum required settings for advertising with Chartboost.



Be sure to double-check that you've copied the correct App ID and Signature from the Dashboard.



Under "Sending option", please select "All media sources" for best performance!

Default Postbacks

INSTALLS is the Default Postback event that is sent automatically.

  • For negative targeting Chartboost requires the value All media sources, including organic be set in the Sending Option.

In-App Event Postbacks

Toggle the In-App Events Postback and choose Add Manually to set up Open and Purchase event postbacks.



No other In-App event types are currently supported by Chartboost.

PURCHASE event postbacks are managed via the af_purchase event and is essential if ROAS/ROI optimization is required.

  • If your app has a significant (100K+ DAUs) existing user base, we recommend setting the Sending Option to All media sources, including organic' for a few weeks to improve negative targeting during onboarding (a device id list to process manually can also be shared as an alternative).
  • If your app is using probabilistic matching/SKAN, 'Advanced Privacy OFF' should be selected in the AppsFlyer dashboard.
