On the Autoplay tab, you can define simple or complex Rules to control whether or not the Journey will start automatically, and if it does, whether it starts only once during the session or every time the Rule conditions are met.
The Rule definition procedures and options are identical to those described previously under Visibility Rules. Again, the dialog always displays the result of the Rule conditions. The only difference is the Play option section.The options are:
1. Only once: If the Autoplay Rules allow the Journey to start ("play") automatically, it will only do so only once during the user's session.
2. Always: If the Autoplay Rules allow the Journey to start automatically, it will do so every time the end-user's interaction satisfies the Autoplay Rule conditions.
TIP: Journey designers can test Autoplay in the Editor application using the menu option Edit > Auto-play.
