Certificate Update

The validity of certificates will be checked when calling the API of the NEN system, so the provided certificates must be valid. If the certificate becomes invalid, the interface cannot be accessed.

It is the responsibility of the applicant's IS to provide a valid certificate in a timely manner. We recommend submitting the updated certificate to the NEN System Operator via CSD NIPEZ at least 5 working days before the current certificate expires.

Only the applicant's designated contact person may submit the request for a certificate update.
