GET /registrations/{registration_id}/oss-countries

List a registration's OSS countries

List the EU member states an EU One Stop Shop registration covers. Searched across every organization your credential owns, so no selector is needed for a known id. Returns 404 if the registration does not exist or belongs to an organization your credential cannot access, so the API never confirms an id exists. A registration that is not an EU OSS scheme returns an empty list.

Category: Registrations

Path parameters:
registration_id (string, required) - The unique identifier of the registration.
