REST API

One page per feature. Each page documents the v1 (API key) and v2 (HelseID) endpoints and the schema of the data they return.

• Treatment groups — treatment-group endpoints and the TreatmentGroup and TreatmentAlternative schemas
• Reimbursement groups — reimbursement-group endpoints and the ReimbursementGroup schema
• Last updated — last-updated endpoints for a cheap check for changes
• Shared types and code systems — ProductReference, Coding, CodeableConcept, Identifier, Period and code systems

v2 (HelseID) endpoints

The v2 endpoints expose the same data and behave identically to their v1 counterparts. The differences are:

• Authentication — a HelseID access token sent with a DPoP proof, instead of the X-API-KEY header. See HelseID (DPoP).
• Rate limiting — v2 endpoints are limited per client IP address instead of per API key. See Rate Limiting.

Response shapes, query parameters, and versioned-diff semantics are identical to the v1 endpoints.
