E-invocing update in Denmark

The NHR API (for e-invocing in Denmark) will be updated on 12 August 2026. While the way systems call the API remains the same — endpoints, HTTP methods, and request parameters are unchanged — the structure of JSON responses will be different.

Developers and businesses integrating with the API should review how they parse responses to ensure compatibility. Testing is encouraged in the demo environment before the new version goes live: api-demo.nemhandel.dk.

The changes are:

• Profile object: Field names changed from camelCase to PascalCase. Flags renamed (IsNhAs4Enabled, IsPeppolEnabled).
• Role object: Field names also changed to PascalCase.
• Participant fields: New Boolean fields ActiveInDkSml and ActiveInEuSml show registration status.
• CertificateBindings: Recipient services now include certificate binding details with activation and expiration dates.
• Additional profile fields: DocumentStandardId and NetworkTypeId added.
• Timestamp field: Last modification is now documented as lastModifiedString.

Demo/Test environment is available now, and production release is planned for 12 August 2026.
