Performed user properties select the last observed property value of a track event.

Performed user properties are calculated synchronously from within event entry Journeys. This guarantees that the user property value will incorporate the triggering events’ properties when rendering message templates within the journey.

​
Example Use Case - Last Purchased Item

As an example, imagine you are running an e-commerce application. You might create a lastPurchasedItem user property, to track the last item that a user purchased.

{
  "type": "track",
  "userId": "1234",
  "event": "purchase",
  "properties": {
    "item": {
      "name": "orange socks"
    }
  }
}

This property would then be available to render in a template.

{{ user.lastPurchasedItem | default: "this amazing item" }}!
