External services

This plugin connects to the VIESAC API to validate VAT numbers, retrieve account usage information, and optionally create audit records with certificate storage.

It sends data to https://viesac.eu only when a store administrator enters an API key and the plugin performs one of these actions:

VAT validation and audit creation via https://viesac.eu/api/v1/audits
Account and usage lookup via https://viesac.eu/api/v1/account

Depending on the action, the plugin may send:

VAT country code and VAT number
Company name
Company address
Order number
Order audit details in XML format for certificate generation
