Recently, I came across one issue while working with one Customer where they were facing bit of challenges to update existing working Integration with new JSON field input.
So, in this use case, two integration orchestration process flow are involved, Master Integration and Child Integration both working well in production. However, time to time developer gets requirement from business to enrich this working flow by adding more fields into Child Integration which was interacting with Oracle Responsys System. The Master Integration getting data from NetSuite, passing Child Integration same data which was interacting with Responsys and completing business flow.
