The eiConsole and eiPlatform support a number of different Listeners which can provide response data back to the calling system. When you wish to provide data back to the Listener to send to the Source System you will configure this through a Synchronous Response Transport.
To configure a Synchronous Response Transport, you must first have a Listener in place that supports a Synchronous Response. The most typical example here would be an HTTP or a Web Service based Transport. Choose this option from the Transport Type drop-down. The Synchronous Response Transport requires no further configuration. When data is received by a Synchronous Response Transport, it will simply take that message and notify the Listener that the message is ready to be returned to the Source System.
