Healthcare APIs

Healthcare APIs and Interoperability Infrastructure

Healthcare data is rarely missing — it is stranded. Actofit builds the API layer that makes it usable: FHIR-native services, integration engines for legacy interfaces, and developer platforms your partners can actually build on.

FHIR-native API services

We implement the standard properly, so any conformant client works on day one and your integration surface stops being bespoke.

  • RESTful FHIR R4 resources with search, includes and pagination
  • Bulk Data Export for analytics and population workloads
  • SMART on FHIR authorisation with scoped, consented access
  • CDS Hooks for decision support inside clinician workflows
02

An integration engine for the real world

Standards coexist with decades of legacy. We normalise everything into one model rather than letting each interface leak into your product.

  • HL7 v2 ADT, ORM, ORU and SIU message handling
  • X12 claims and eligibility transactions for payer workflows
  • DICOM metadata indexing and imaging study references
  • CSV, SFTP and database replication feeds from legacy vendors
03

Governance is part of the API

In healthcare an API is a compliance boundary. Authorisation, consent and audit are enforced by the platform, not by each consuming application.

  • OAuth 2.0 and OpenID Connect with fine-grained scopes
  • Consent and purpose-of-use checks on every request
  • Per-client rate limiting, quotas and anomaly detection
  • Immutable access logs suitable for regulatory review
04

A developer platform partners want to use

Adoption is a documentation and tooling problem as much as an engineering one. We ship the whole developer experience.

  • OpenAPI and FHIR CapabilityStatement generated from the implementation
  • Sandbox environments with realistic synthetic patient data
  • Typed client SDKs and webhook subscriptions for change events
  • Versioning and deprecation policy that protects existing integrations

Questions

Healthcare APIs — frequently asked

A healthcare API is a governed interface that lets applications read and write clinical, administrative or device data in a standard format — most commonly FHIR R4. It replaces bespoke point-to-point integrations with one authorised, audited and versioned access layer.

FHIR gives you a shared resource model, an ecosystem of conformant clients and tooling, and a much shorter path through partner and regulator review. Custom APIs push modelling and mapping effort onto every integrator and tend to fossilise around one vendor's assumptions.

Yes. Our integration engine ingests HL7 v2 messages, X12 transactions, DICOM metadata, flat files and direct database feeds, normalises them into FHIR resources and exposes them through the same governed API surface.

Through OAuth 2.0 and SMART on FHIR scopes, combined with consent and purpose-of-use checks evaluated on every request. Access is granted per client, per resource type and per patient relationship, and each call is written to an immutable audit log.

Yes. Every API platform we build ships with a sandbox containing realistic synthetic patient data, generated OpenAPI and FHIR CapabilityStatement documentation, and typed SDKs so partners can integrate without touching production data.

We version at the interface level with an explicit deprecation policy, run old and new versions in parallel for an agreed window, and use webhook and changelog notifications so existing integrations are never broken without notice.
