The "Invoke IS Service" Step (Inbound, Connector Virtual Service, REST)
This optional step invokes a user-defined Integration Server flow service. An IS service is a user-defined Integration Server flow service that you can invoke in:
The "In Sequence" step, to pre-process the request messages before
CloudStreams submits the requests to the native service.
The "Out Sequence" step, to pre-process the response messages from the native service before
CloudStreams returns the responses to the consuming application.
You create an "Invoke IS Service" step for a connector virtual service the same way you create one for a virtual service. For details, see
The "Invoke
IS Service" Step (Inbound, REST), or
The "Invoke
IS Service" Step (Outbound, REST).
