If you want to connect to our online data interface and transfer the data of invoices and/or transactions to your own system...
Get in touch with us through contact or email and request registration of your system at Számlázz.hu. You can read more about this in the registration section. Once this is done,
create a test account, or use your existing live account.
In the settings of your billing account, under the Online Financial Data Connection tab, activate data transmission. To do this, select your system from the drop-down list. Also, provide the identification key and dates. (In the case of a hidden connection, contact our IT support for assistance with the setup.)
