I am wondering if it is possible to update my CATALOG with an external source in KLAVIYO.
I am using an old version of PRESTASHOP v1.6 and i need to add custom variable to the KLAVIYO CATALOG.
I want to update my TITLLE and to add a some custom variable to products.
I looked at the help center, but i did not find the info.
If someone knows how to do it, thanks.
