You have determined that in your HL7 interface you will be needing to create HL7 messages and now it's time to plan for which transport mechanisms you are going to support which will allow you to deliver those messages to your trading partner(s).

Where is your outbound interface ENDPOINT going to be? As with Receiving HL7 Messages, the governing body of HL7 gives you a clue about what this endpoint should be.

Now, obviously, if the trading partner which needs to receive the HL7 messages is on a remote server you might not want to let them join your WAN and make a folder available to them. However, by using a data file drop as your interface endpoint you can easily all of the other Message Transport mechanisms.
