The On Event Starter immediately takes users into the journey when they perform a specific event. This starter tracks user events across all platforms – website, mobile app, and offline environment. It helps you run real-time use cases since it takes users into the designated journey as soon as they complete a specified event.
The video above introduces the On Event starter.
This article explains the following:
When the user performs the event, they can only enter the journey once, unless they go through the same event again.

Additional segmentation
You can add more segments to your starter condition to target your audience more precisely. For example, you can take the users who perform the cart page view event and have a high Likelihood to Purchase value.
Users can enter the journey if they perform the selected event and meet the optional segment filter criteria.
You can select predefined segments, standard segments, predictive segments, integrated segments, RFM segments, and saved segments to filter your users to take into the journey..png)
