Laravel 5 package for EVATR - Validating VAT IDs

This library is a wrapper for the XmlRPC interface to validate European VAT IDs.
See https://evatr.bff-online.de/eVatR/xmlrpc/ (German version).

With this library you can check an European VAT ID if it is valid. Additionally you can pass in and address of this European VAT ID and do an address check.

The library supports the simple and the qualified request.

• Simple request:
  • Checks if a certain foreign VAT ID is valid at the time the request is made.
• Qualified request:
  • Additionally checks if the address (company name, street, city and zip code) connected to the VAT ID matches with registered data in the foreign country.

All error messages are available in English or German - of course you can modify those as you like.

Install with Composer

To install the library using Composer:

$ composer require codedge/laravel-bzst-evatr

This adds the codedge/laravel-bzst-evatr package to your composer.json and downloads the project.

Next run: php artisan vendor:publish to publish the translation files of the library to resources/lang/vendor/evatr/<locale>/messages.php.

Don't forget to add the Service Provider to your config/app.php [1] and optionally the facade [2]:

// config/app.php

return [

    //...
    
    'providers' => [
        // ...
        
        /*
         * Application Service Providers...
         */
        App\Providers\AppServiceProvider::class,
        App\Providers\AuthServiceProvider::class,
        App\Providers\EventServiceProvider::class,
        App\Providers\RouteServiceProvider::class,
        Codedge\Evatr\EvatrServiceProvider::class, // [1]
    ],
    
    // ...
    
    'aliases' => [
        'App' => Illuminate\Support\Facades\App::class,
        'Artisan' => Illuminate\Support\Facades\Artisan::class,
        
        // ...
        
        'View' => Illuminate\Support\Facades\View::class,
        'Evatr' => Codedge\Evatr\Facades\Evatr::class, // [2]

]

Usage

If using the facade, just do:

// app/Http/routes.php

Route::get('/', function () {

    Evatr::setOwnUstId('123');      // Or use an alias: Evatr::setUstId1('123');
    Evatr::setForeignUstId('123');  // Or use an alias: Evatr::setUstId2('123');
    
    Evatr::query(); // Fires the XmlRpc call

    echo 'Error code: ' . Evatr::getResponse()->getErrorCode();
    echo 'Error message: ' . Evatr::getResponse()->getErrorMessage();

    echo 'Date: ' . Evatr::getResponse()->getDate();
    echo 'Time: ' . Evatr::getResponse()->getTime();

});

Alternatively you can use the dependency injection of the singleton instance like so:

// app/Http/routes.php

Route::get('/', function (Codedge\Evatr\Evatr $evatr) {

    $evatr->setOwnUstId('123')
          ->setForeignUstId('123')
          ->query(); // Fires the XmlRpc call

    echo 'Error code: ' . $evatr->getResponse()->getErrorCode();     // Get the interface error code
    echo 'Error message: ' . $evatr->getResponse()->getErrorMessage();  // Get the interface error message
    
    echo 'Date: ' . $evatr->getResponse()->getDate();
    echo 'Time: ' . $evatr->getResponse()->getTime();

});

All date and time methods return a Carbon instance for better and further handling.
