Some Events are dependent on certain features being enabled.For instance, Events focussing on NPS or Propensity to Refer require Campaigns for NPS or Smart Experiments to be being actively promoted to Customers respectively.If you’d like to know more about these features, please speak to your Account Manager.
Events are all the different types of actions Customers can do, which can be subscribed to by external systems. These events underpin many of our most central Customer actions, like when a Referrer is Registered, or a Referee receives their reward. And can intern drive functionality in your external systems. For instance, you may wish to update a customer record when a customer successfully refers their friend, send out an email when a customer receives a reward for referring, or apply credit to an account in real-time when a reward is received.
