info

If you restrict access by IP (e.g. your system only accepts requests from certain addresses), whitelist these outbound IP addresses.

HTTPS certificate​

In the case of the Számla Agent service, LET'S ENCRYPT is our certificate issuer. This may only affect very old systems where the missing root CA must be installed manually.

The SSL certificate is available on the website https://certtest.szamlazz.hu, and it is renewed every 3 months. The connection is based on a 256-bit encrypted SSL connection.
