How HL7 v2 is transformed into FHIR R4
Turn legacy HL7 messages into usable FHIR — step by step.
A practical Hgear session showing how HL7 v2 messages move through transformation, mapping, error visibility and FHIR bundle generation.
Leave with a clearer picture of the workflow.
The session moves from product behavior to implementation detail, then into practical questions teams commonly face.
How to upload messages or start from sample data
How generated FHIR bundles are structured
How segments map to FHIR resources
How common transformation errors surface
How to export generated bundles
How API workflows can support repeatable conversion
Understand the problem before the product solves it.
HL7 v2 remains deeply embedded in healthcare systems
Modern applications increasingly need structured FHIR data
Manual mapping and transformation introduce avoidable friction
Teams need repeatable transformation and validation workflows
