Overview

Orion Health is an enterprise healthcare platform API that enables developers to build clinical applications supporting patient management, electronic health records, and care coordination workflows. It uses OAuth 2.0 for secure authentication and follows HL7 FHIR standards for health data interoperability. This API is best suited for developers working within established healthcare IT environments.

💡

Beginner Tip

Start with the sandbox environment using provided test credentials before requesting production access — this lets you explore FHIR resources like Patient and Observation without needing real patient data.

Available Data

vehicle make and model
year and specifications
fuel economy
VIN decode data
case counts and statistics
vaccination data

Example Response

JSON Response 
{
  "make": "Toyota",
  "model": "Camry",
  "year": 2025,
  "engine": "2.5L 4-cylinder",
  "fuel_economy": {
    "city_mpg": 28,
    "highway_mpg": 39
  },
  "msrp": 28400
}

Field Reference

resourceType The FHIR resource type returned, such as Patient, Observation, or Bundle.
id Unique identifier for the FHIR resource within the system.
name Patient name components including family name and given names.
birthDate Patient date of birth in YYYY-MM-DD format.
entry List of FHIR resources returned in a Bundle response.
total Total count of matching resources in a search Bundle response.

Implementation Example 

const url = "https://developer.orionhealth.io/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized The OAuth access token is missing, expired, or invalid
✓ Re-authenticate using the OAuth 2.0 client credentials or authorization code flow to get a fresh access token.
403 Forbidden Your application does not have permission for the requested FHIR resource
✓ Ensure your OAuth scopes include the necessary FHIR resource permissions (e.g., patient/*.read).
404 Not Found The FHIR resource ID does not exist in the sandbox or tenant
✓ Use the search endpoint (e.g., /Patient?name=test) to discover available resource IDs first.
