FAQ

Why is person data missing from my ad destination events?

Ad destinations filter the realtime event stream. This means they use person data as it exists at the exact moment the event is processed, not data added later.

A common issue occurs when a backend event triggers the destination, but person properties are set by a frontend identify call that happens afterward. If the identify call merges with the person after the trigger event is processed, the destination won't have access to that data.

To fix this, either:

  1. Include the data directly in the event that triggers the destination (e.g., pass email, phone, or other required properties as event properties)
  2. Ensure the identify call happens before the events you want to send to the ad platform
