Secure APIs for Healthcare — Australia

Design, build and operate FHIR-ready, auditable APIs with privacy-first controls, data residency and cloud-native scalability tailored for hospitals and digital health providers.

FHIR & HL7 integrations
Role-based access & OAuth2 / OpenID Connect
End-to-end encryption, auditing and monitoring

Overview

Bunyadevcode builds secure API platforms that integrate clinical systems, telehealth, devices and patient apps. We prioritise privacy, compliance with Australian regulations, and pragmatic engineering that supports rapid iteration.

Privacy & compliance Security controls

Architecture highlights

Cloud-native, containerised services, API gateway with mTLS, schema validation, request throttling and observability built-in.

API Gateway & Authentication (OAuth2, mTLS)
Schema validation (FHIR/JSON Schema)
Audit trails and immutable logs

Security & compliance

Security controls designed for healthcare data protection and operational transparency.

At-rest encryption with customer-managed keys, field-level crypto for PHI, TLS 1.3 in transit and envelope encryption for backups. Integrations available for cloud KMS providers.

OAuth2 + OpenID Connect, fine-grained RBAC, consent-scoped tokens, and integration with enterprise identity providers for single sign-on and conditional access.

Immutable audit logs, real-time alerting, SIEM export, structured eventing for every API call, and playbooks for incident containment tuned for clinical settings.

Deployments within Australian regions, controls for data export, and support for compliance evidence aligned to local privacy requirements and health data handling guidance.

Integration & API samples

Example endpoints and typical payload considerations for record exchange and device telemetry.

Endpoint	Method	Purpose
/api/v1/fhir/Patient	GET / POST	Search and create patient records (FHIR R4)
/api/v1/observations	POST	Device telemetry (validated schema)
/api/v1/audit/events	GET	Retrieve audit logs with filters

Tokens scoped to minimal privileges, payload validation against FHIR profiles, and rate limits per client.

Deployment options

Managed cloud in Australian regions
Private VPC / on-prem gateway
Hybrid models with edge data processors

Case study & team

We partnered with a metropolitan hospital network to deliver a FHIR-based exchange, improving discharge summaries and device telemetry ingestion. The project included scoped PII minimisation and on-premise connectors for legacy systems.

Project delivered in 4 sprints with dedicated security reviews and SOC-style logging exports.
