Welcome to ClinikAPI

ClinikAPI is a managed healthcare infrastructure platform that lets you build clinical applications through a simple REST API and SDK — without dealing with FHIR R4 complexity, HIPAA compliance infrastructure, or cloud provisioning.

What ClinikAPI Does

You send simplified JSON. We handle the rest:

FHIR R4 transformation — your payloads are automatically converted to strict FHIR R4 resources
Tenant isolation — every resource is tagged and filtered by your organization
Secure storage — data lives in an encrypted, HIPAA-compliant FHIR R4 data store
Compliance — BAA-ready infrastructure with audit logging on every request

import { Clinik } from '@clinikapi/sdk';

const clinik = new Clinik(process.env.CLINIKAPI_SECRET_KEY);

// Create a patient — ClinikAPI handles FHIR transformation + storage
const { data: patient } = await clinik.patients.create({
  firstName: 'Jane',
  lastName: 'Doe',
  email: '[email protected]',
  gender: 'female',
  birthDate: '1990-03-15',
});

console.log(patient.id); // "pt_abc123"

Architecture

ClinikAPI is a data API — you bring your own auth (Clerk, Auth0, Firebase, etc.).

Your App → Your Backend → ClinikAPI SDK → ClinikAPI REST API → FHIR R4 Data Store

The SDK runs server-side only with a secret API key
React widgets use a proxy pattern — they talk to your backend, not directly to ClinikAPI
Test keys route to a shared test datastore; live keys route to production
