Interface Development

Everything you need to build a Linkiir interface: how projects are structured, which node types to use, how to write and test Lua, and how to handle failure.

Project → Workflow → Node

New to Linkiir? Getting Started builds a working HTTP interface step by step first.

The shape of an interface

Source  →  Transform  →  Destination

You configure transports with fields and write Lua only where the logic is yours — HTTP handling, transformation, and generated or fetched messages.

Palette group	Node	Role
Source	HTTP	Receive HTTP requests
Source	LLP	Receive HL7 v2 over MLLP
Source	File/FTP	Poll a directory or FTP/FTPS/SFTP server
Source	Custom	Fetch or generate messages on a timer
Transform	Custom	Process each inbound message
Destination	File/FTP	Write files, locally or over FTP/FTPS/SFTP
Destination	LLP	Send HL7 v2 over MLLP with ACK handling
