README

A Laravel package for EU VAT validation and VERIFACTU support. This package can be used with any invoicing system (SIF). You must submit the declaration of responsibility (declaración responsable) for your system yourself.

Please note: Canary, Ceuta and Melilla tax modes are not supported.

Installation

Prerequisites

PHP 8.3 or above with the dom, json, libxml, openssl, and soap extensions installed and enabled. Laravel 11 or 12 is required.

Requirements for QR Code Generator

• ext-gd for Gdlib based output or
• ext-imagick with ImageMagick installed
• ext-fileinfo required by Imagick output

OpenSSL Configuration

The Spanish FNMT certification authority uses outdated encryption algorithms that are not supported by OpenSSL 3.0 and above.

For OpenSSL versions higher than 3.0, you must enable legacy encryption methods. To do this, open your openssl.conf (e.g., /etc/ssl/openssl.cnf on Ubuntu/Debian) and add the following:

[openssl_init]
providers = provider_sect

# List of providers to load
[provider_sect]
default = default_sect
legacy = legacy_sect

[default_sect]
activate = 1

[legacy_sect]
activate = 1

To install the package, run:

composer require taiwanleaftea/tlt-verifactu

php artisan vendor:publish --tag=tlt-verifactu --ansi --force

The package will be installed, and config/tlt-verifactu.php will be published.

Open your .env file and add the variables VERIFACTU_PRODUCTION (set to true to use the production AEAT server) and VERIFACTU_DISK (the disk where SSL certificates are stored).

Usage

VAT Number Validator

use Taiwanleaftea\TltVerifactu\Support\VatValidator

// Offline validation by format
echo VatValidator::formatValid('ES', 'B12345678');

// Online validation via the VIES service
$response = VatValidator::online('ES', 'B12345678');
if ($response->success) {
    // VAT number present in the VIES database
    echo $response->valid;
    // Data returned from the VIES database (varies per country)
    echo $response->vatNumber;
    echo $response->countryCode;
    echo $response->requestDate
    echo $response->name
    echo $response->address;
} else {
    foreach ($response->errors as $error) {
        echo $error . PHP_EOL;
    }
}
