A system, method and the like for seamlessly integrating disparate applications, such as channel applications and off-the-shelf business process management services/applications through use of a core process framework that provides a vendor/third-party entity-agnostic approach to application integration. The core process framework provides various fundamental processes that are shared amongst applications that are in communication with the framework. The core process framework leverages a headless business process management and middleware integration patterns that serve to create an open architecture with reduced dependency on the third-party entity/vendor providing the business process management service. In this regard, the core process framework of the present invention provides a service platform that clients (i.e., channel applications) can make service requests/calls to, via an integration gateway or the like, to perform multiple different generic business process management engine-related operations.
