A method and corresponding system for secure messaging between an edge application and internal business process. The method includes converting a client request in an object state into a network message, e.g., a markup language message, based on a data definition. A network connection is opened and the network message is transmitted from the edge application to a messaging application associated with the internal business processes, which maps the network message is mapped to one of the business processed based on the type of data object or object state of the network message. The network message is converted back to its original state using the data definition, and the converted network message is passed to the mapped business process for processing to create a response or response data object. The mapping step typically includes reading a configuration file that defines pairings between data object types and business objects.
