Event postbacks to Facebook
If you acquire users from app-install campaigns on Facebook, you can designate specific in-app conversion events to post back to Facebook. When a user you acquired from Facebook completes one of the in-app events you designate, Localytics uses an API call to send the information back to Facebook. Use this data to work with your Facebook account manager to measure and improve the performance of your Facebook campaigns or to create audiences in the Facebook Ads Manager.
To achieve this, you simply perform the basic setup for the Facebook-Localytics integration as documented in our Facebook attribution article, then navigate into Attribution Settings within the Localytics dashboard and select the Events you want Localytics to post back to Facebook. Every Event that you select from Localytics must be mapped to a corresponding Conversion Event that you define within the Facebook interface.
Facebook maintains more detailed documentation on their event names.
If you're not sure which Facebook event name to choose for your postback, contact your Facebook account manager.
