Authentication

The Ferrum supports various authentication mechanisms depending on your deployment configuration.

Bearer Token Authentication

Most deployments use Bearer token authentication. Include the token in the Authorization header:

curl -H "Authorization: Bearer YOUR_TOKEN" \
     https://your-server.com/fhir/Patient/123

Some deployments may use API keys. Include the key in a custom header:

curl -H "X-API-Key: YOUR_API_KEY" \
     https://your-server.com/fhir/Patient/123

For OAuth 2.0 authentication, follow the standard OAuth 2.0 flow:

curl -H "Authorization: Bearer ACCESS_TOKEN" \
     https://your-server.com/fhir/Patient/123

Some endpoints may be configured for public access (read-only). Check your server configuration for details.

Always use HTTPS in production to protect authentication credentials.
