Getting started
Install and activate the plugin.
Go to WooCommerce -> VIESAC.
Get your free API key from https://viesac.eu/app/api.
Enter the API key and save.

Multilingual compatibility
VIESAC uses standard WordPress gettext for its interface and VAT validation messages, so it works with WordPress language packs and the Gettext translation tools in WPML, Polylang, and TranslatePress.
Custom VAT field label and VAT field placeholder values are supported too:
WPML: translate them in WPML -> String Translation after saving the VIESAC settings.
Polylang: translate them in Languages -> String translations after saving the VIESAC settings.
TranslatePress: translate them as regular strings in its translation editor after visiting checkout in the target language.
