Request and response callback events
A request and response callback event is a synchronous operation in which the EIS sends a callback call to the adapter and waits for the adapter to respond to the call.
Since the EIS expects a response from the adapter, event delivery to multiple endpoints cannot be supported.
The following is an illustration of synchronous callback event processing.
