Netherlands

What this means

The Netherlands is the clearest public example of a national short-term rental data-sharing interface currently visible. SDEP Netherlands is referenced by the public SEMICeu SDEP repository as the production reference implementation.

For platforms and software vendors, the Dutch implementation is useful because it shows the expected direction of travel: authenticate as a platform, identify the relevant regulated area, submit structured activity data, and let competent authorities retrieve that data through authority-facing endpoints.

Implementation status

The public documentation describes SDEP Netherlands as a gateway for electronic transmission of short-term rental data between online short-term rental platforms and competent authorities.

The implementation separates platform-facing STR endpoints from competent-authority CA endpoints. Platforms use the STR API to retrieve regulated-area information and submit activity data. Competent authorities use the CA API to manage regulated areas and retrieve activity data relevant to their scope.

The public reference also shows that regulated areas are operationally important. Authorities can publish area information, including geospatial boundary data, and platforms may need to match rental addresses or geometries to an area identifier before submitting activity data.

Technical interface

Public API documentation is available at sdep.gov.nl/api/docs. The visible API surfaces are Common, Auth v1, CA v1, and STR v1.

The Auth API exposes token-based machine-to-machine authentication. The public reference implementation uses OAuth2/OIDC with JWT bearer tokens and role-based access for platform and competent-authority operations.

The STR API includes regulated-area discovery and bulk activity submission for platform-side reporting. The CA API includes area registration/retrieval/deactivation and activity-data retrieval for competent authorities.

The observed OpenAPI version string on 2026-05-12 was PRD-0.0.1-2605062320 across Common, Auth, CA, and STR documentation.

The public SEMICeu SDEP repository describes a FastAPI/PostgreSQL/Keycloak implementation with Docker Compose and a pre-production environment for integration partners. Repository documentation states that PRE data should be anonymised and that the environment is cleaned daily.

A practical integration implication is GIS handling: platforms may need to download regulated-area shapefiles, validate coordinate reference systems, spatially match unit addresses or geometries, and include the resulting areaId in activity submissions.
