Hello Patrik,
Yes, to add the UF. It’s just when they are paying that is “necessary” to gather the UF price data (from “Banco Central de Chile”, it’s like BOE in the UK).
Maybe what’s needed is adding that currency to tell the Webpay plugin to use that at the checkout, webpay should do the conversion.
Hope this makes sense, I’m afraid I don’t have enough experience in this topic.
Thank you!
