The simplest way we generally set up message exchange is via message files on the file system. 1 message per file. Save them into a directory that MO can access. We can also provide you with acknowledgements so that you can determine in your software how far the message has gone through the network. eg. is it waiting to route, on the hard disk at the other end or waiting for an application to process, or it has been imported into the system successfully.
Once you have prepared your message, please use our HL7 Lint testing site on your example messages. HL7 Lint will check for common mistakes and ensure items necessary for transmission on the Medical-Objects network are populated properly. Please contact MO if you require assistance with this site.
