Changelog#

23-10-2026#

Corrected the PKCE challenges in the PAR example and implementation guide to match the documented token request verifier.
Updated the public and full OpenAPI specifications to describe EC signing keys and their certificate chain in the JWKS response.
Fixed the changelog link to the document details fields.

The OpenAPI specification is now embedded with Swagger UI at the existing /api/openapi/ URL.

Added jti claim to the ID token, providing a unique identifier for each issued token

Added Data Validation guidance to ID Token documentation, clarifying RP responsibility for validating identity data against their own compliance requirements

Updated OpenAPI spec examples: all authorization callback and error redirect URIs now include the iss parameter per RFC 9207
Updated Implementation Guide with iss parameter in callback example and validation guidance
Updated Implementation Guide token response example with access_token and token_type fields
Updated Common Errors with iss parameter in error callback example and handling steps

Authorization response iss parameter: The authorization callback now includes the iss parameter per RFC 9207⁠ (opens in a new tab), enabling relying parties to verify the identity of the authorization server that issued the response.
Token response token_type field: The token response now includes token_type: "Bearer" per RFC 6749 §5.1⁠ (opens in a new tab).
Token response access_token value: The access_token field now returns "not_applicable" instead of an empty string. DIP is an identity verification service where the ID token is the primary artifact.
Token endpoint cache headers: The token endpoint now returns Cache-Control: no-store and Pragma: no-cache headers to prevent caching of token responses.
Discovery metadata: Added authorization_response_iss_parameter_supported, code_challenge_methods_supported, and grant_types_supported to the OpenID Configuration endpoint.

personal_number in document details is now always a plain string: For Norwegian documents, this is the fødselsnummer (NNIN). For non-Norwegian documents, this may contain a national identification number from the issuing country, or may be absent.

Document details Changed how document issuer is requested
- Requesting document issuer details is now done by setting "issuer": null in the document_details object of the PAR request.
- No changes in how it is presented in the ID Token.

Updated PAR documentation to reflect new request format for document issuer details

Document Check Details: Added OIDC4IA-compliant check_details array on document evidence, always included in the response
- vcrypt entry for active authentication result (always present)
- data entry for issuer registry verification (present when issuer check is available)

Removed active_authentication_result and issuer_check from document_details: These legacy fields have been replaced by the check_details array on the document evidence object. Remove these fields from your PAR request document_details and read verification results from check_details instead.
Discovery config documents_check_methods_supported changed: Changed from ["bvr"] to ["vcrypt", "data"].

OIDC4IA trust_framework format: trust_framework must be an object with a value field
- Example: {"trust_framework": {"value": "stoe"}}
- trust_framework is required when requesting verified claims
