Although none of the pre-packaged adapters currently use synchronous data transport, this option is available for customized connectors.
Programs that use synchronous messaging transport post request messages to the integration broker on a synchronous request queue and receive response messages from the integration broker from a synchronous response queue. A correlation ID on the response message identifies the request message to which it is responding. Response messages generally consist of business object messages and a status indicator that shows whether the request was processed successfully.
