e-Factura: API accounts to be deactivated on 30 October from 17:00

On 30 October, from 17:00, the State Tax Service will deactivate all active API accounts in the e-Factura system. These accounts let companies’ accounting software and other IT systems connect to e-Factura automatically.

The move follows the recent wave of cyberattacks and is meant to protect data and block unauthorised access. To keep exchanging data automatically, companies must create new API accounts that meet the updated security requirements. Instructions for fully and partly automated integration are published on the tax service website.

What it means for you

• If you issue invoices from 1C or other software linked directly to e-Factura, the connection will stop working after 17:00 on 30 October.
• Warn your accountant or software provider now and plan the reconfiguration right after 17:00, as the tax service recommends.
