Byte8\_VatValidatorHyva — Hyvä companion for Byte8\_VatValidator
================================================================

[](#byte8_vatvalidatorhyva--hyvä-companion-for-byte8_vatvalidator)

Adds a live, debounced VAT-validation indicator to Hyvä-themed registration and address forms. Calls the standard `Byte8_VatValidator` REST endpoint and shows a green / red badge directly under the VAT input as the customer types.

Requirements
------------

[](#requirements)

- `byte8/module-vat-validator` ≥ 0.1.0
- A Hyvä-based theme (`hyva-themes/magento2-default-theme`)
- No additional JS dependencies — Alpine + Tailwind only, both ship with Hyvä

Core module
-----------

[](#core-module)

This is a storefront companion — it does nothing on its own. Install the core validator first: **[byte8/module-vat-validator](https://github.com/byte8io/magento-vat-validator)**. That module provides the EU VIES / UK HMRC / Swiss UID validation, REST endpoints, customer-group mapping, audit log, and CLI. This module just wires a live indicator into Hyvä forms.

```
composer require byte8/module-vat-validator
```

Install
-------

[](#install)

```
composer require byte8/module-vat-validator-hyva
bin/magento module:enable Byte8_VatValidatorHyva
bin/magento setup:upgrade
bin/magento cache:flush
```

What it does
------------

[](#what-it-does)

PageBehaviour`customer/account/create`Watches the `taxvat` field; shows live indicator`customer/address/form`Watches the `vat_id` + `country_id` fields; shows live indicatorBehaviour:

- 600 ms debounce — won't spam the REST endpoint while the user types
- Recognises both 2-letter ISO prefixes (`DE…`, `GB…`) and the Swiss 3-letter `CHE…` prefix
- Falls back to the country dropdown's value if no prefix is typed
- Hides itself silently on `unavailable` / `skipped` outcomes — never shows a misleading red badge when VIES is just slow

Customising
-----------

[](#customising)

Override `Byte8_VatValidatorHyva::vat-indicator.phtml` in your theme. The whole component is a single self-contained Alpine `x-data` block — drop in your own copy / icons / Tailwind classes.

Hyvä Checkout (Magewire)
------------------------

[](#hyvä-checkout-magewire)

Not yet shipped. The standard Hyvä Checkout uses Magewire components which need a server-side wire-class. Open an issue if you need it and we'll prioritise.
