Legacy Investment
Billions of dollars invested in HL7 v2 infrastructure. Replacing it overnight is neither practical nor cost-effective.
Healthcare Messaging
HL7 v2 Connector
Bridge legacy healthcare messaging systems with modern integration. Parse, transform, and route HL7 v2 messages through secure pipelines.
Coming Soon
The Challenge
HL7 v2 remains essential
Modernisation Pressure
New applications expect FHIR and REST APIs. Bridging old and new requires transformation infrastructure.
Message Complexity
HL7 v2 messages are pipe-delimited text with complex nesting. Parsing and transforming reliably requires specialised tooling.
The Solution
HL7 v2 as a first-class citizen
Harmony's HL7 connector parses messages into JSON, enabling the same transformation and routing capabilities available for modern protocols.
Message Parsing
Parse HL7 v2 messages into structured JSON for transformation and routing.
Segment Handling
Access and modify individual segments (MSH, PID, OBR, OBX, etc.).
MLLP Support
Native Minimal Lower Layer Protocol for HL7 message transport.
HL7 to FHIR
Transform HL7 v2 messages to FHIR resources using declarative mappings.

Message Types
Common HL7 v2 message types
Route and transform any HL7 v2 message type through Harmony pipelines.
