Healthcare Prior Authorization Integration
An anonymized healthcare integration case study connecting HL7 FHIR R4 style workflows with legacy SOAP services for real-time authorization processing.

Problem
Modern authorization workflows needed to exchange structured clinical and administrative data while still relying on existing SOAP-based systems of record.
Context
The integration had to support healthcare interoperability expectations, secure data handling, and operational visibility across multiple services.
Technical approach
Model the modern API boundary around FHIR R4 resource patterns, translate where legacy services required SOAP contracts, and keep validation close to the integration edge.
Architecture notes
The design separated canonical request handling, legacy adapters, audit-friendly logging, and response normalization to keep each concern testable.
Tradeoffs
Preserving legacy compatibility added translation complexity, but it avoided a high-risk replacement of systems that still owned important business rules.
Outcome
The workflow supported real-time authorization processing while creating a clearer path for future interoperability improvements.
What I learned
Healthcare integration work rewards explicit contracts, careful failure states, and respect for the systems that still carry institutional knowledge.
Working thesis
Healthcare integration work benefits from clear boundaries: a modern API model at the edge, explicit translation for legacy systems, and careful handling of security, audit, and failure states.
This anonymized case study uses HL7 FHIR R4 and Da Vinci PAS style concepts as the modern workflow shape while acknowledging the reality of legacy SOAP services.
Implementation notes
- Keep FHIR-style request modeling separate from legacy SOAP adapters.
- Normalize responses before they reach the rest of the application.
- Make validation and error states explicit enough for operational support.
- Avoid burying healthcare business rules inside generic transport code.
