In versions 9.0 and later, Integration Server creates a responseServices folder along with connectors and docTypes folders when you create a consumer web service descriptor.

The responseServices folder contains a response service for each In-Out and Robust-In-Only MEP operation in the WSDL document from which the consumer web service descriptor is created. Response services are flow services to which you can add custom logic to process asynchronous SOAP responses. Integration Server creates the response services only if the consumer web service descriptor:

Integration Server invokes the response services for processing asynchronous SOAP responses received for the associated consumer web service descriptor. That is, Integration Server invokes a response service when Integration Server receives a SOAP response with the endpoint URL pointing to a consumer web service descriptor and if this SOAP response contains a WS-Addressing action through which the response service can be resolved.

The responseServices folder also contains a genericFault_Response service, which is the default response service that Integration Server invokes when Integration Server cannot determine the specific response service for a SOAP response or if there are errors while processing the response.
