When creating SOAP message functions, you can configure the function to be sent through a MID Server.

There must be a running MID Server associated with your instance to use this functionality. All SOAP messages sent through a MID Server are performed asynchronously.

By specifying a MID Server, all SOAP requests that use this SOAP message are sent through that MID Server. You can override the selected MID Server by using the setMIDServer(mid server) API call in a script.
