Creating HL7 interfaces in Iguana follows a simple repeatable pattern:

- Translate/map your messages into the outgoing message
- Filter out any unwanted messages
- Deal with unknown message types
The following pages in this article give a brief description of these stages. We also discuss what to expect in a VMD file structure.
