I would like to know if it is possible to accomplish the following:
In a flow, I have a trigger for an event called "Carrier Delay". I would only like profiles to enter this flow if they have recorded an "On Its Way" event in the last 30 days, where the event.notification_triggered_by_tracking_number for the "On Its Way" event matches the event.notification_triggered_by_tracking_number for the "Carrier Delay" trigger event.
I tried setting a profile filter on the trigger as:
What someone has done (or not done)
Person has: On Its Way
Where: notification_triggered_by_tracking_number
Equals: {{ event.notification_triggered_by_tracking_number }}
When: at least once in the last 30 days
In previewing the trigger filter, no profiles that I would expect to enter the flow.
Is it possible to build a trigger filter based on the value of a variable from the trigger event? I do not want to save this as a profile property.
