Magento 2.3

[kpitn]

The module is not yet compatible with Magento 2.3.

You need to add new interface to avoid "Invalid Form Key. Please refresh the page."

Hi, I'm having the same issue here with Magento 2.3.4.
It was working fine until now.

Any news on this ?

Well, there's another package right here, but the doc is not quite right :
https://github.com/PayboxByVerifone/Magento-2.3.x/

I will have a try with
composer require paybox/epayment23
