External Interfaces
This interface is provided by the orchestration platform and is used to control the execution of the orchestration logic by external systems, as well as by other orchestration logic. These interfaces also provide information on the execution of the orchestration logic to external systems. They come in two different forms. One is for external systems (Web Services and HTTP) and the other is for other orchestration logic running in the platform (for details on this, see the
SCXML
and SCXML Extensions
sections).
