We kindly inform you that this weekend 29-30.05.2021 a new SSL certificate will be installed, used to secure communication (https) with our website and API interface. The new SSL certificate was issued by a trusted issuer, so the change of the certificate should not affect the users' systems integrated with our API, as long as the User does not perform any non-standard method of verifying this certificate on the side of these systems. The API address, of course, remains unchanged.
If you have any questions or technical problems, please contact Customer Service Office.
