Export activity to External system

Hi Team

We have requirement that some of work load from OFS can be exported to external system in which they can process these activity in their system. Also, when they have follow customer journey from their system we can get updated back.

Do we have any feature which can help to export the activity information to external application which is out of the box ?

I know one of the potential option could be using application configuration which can make external application to subscribe events and this is help in create activity in their system and later perform action.

Still, I would like to know if there is any more feature which I may not be aware and much simpler and configurable .
