📦 Multiple PHP Versions: This package is tested against PHP 8.1-8.4. See PHP_VERSIONS.md for testing with different versions locally.

Installation

You can install the package via composer:

composer require csoellinger/php-laravel-fon-ws

Publish Configuration

Publish the configuration file to customize the package:

php artisan vendor:publish --provider="CSoellinger\Laravel\FonWebservices\FonWebservicesServiceProvider" --tag="fon-webservices-config"

This will create a config/fon-webservices.php file in your application.

Configuration

The package reads credentials from the config/fon-webservices.php file. By default, it uses environment variables, but you can configure credentials from any source (database, cache, config files, etc.).

Option 1: Using Environment Variables (recommended for local development)

Add to your .env file:

FON_TE_ID=your_teilnehmer_id
FON_TE_UID=your_teilnehmer_uid
FON_BEN_ID=your_benutzer_id
FON_BEN_PIN=your_benutzer_pin

Option 2: From Database (recommended for production)

Edit config/fon-webservices.php:

'credentials' => [
    'te_id' => DB::table('settings')->value('fon_te_id'),
    'te_uid' => DB::table('settings')->value('fon_te_uid'),
    'ben_id' => DB::table('settings')->value('fon_ben_id'),
    'ben_pin' => decrypt(DB::table('settings')->value('fon_ben_pin')),
],

Option 3: From Cache or Other Sources

'credentials' => [
    'te_id' => Cache::get('fon_credentials')['te_id'],
    // ... or any other source
],

⚠️ Security Warning: Never commit credentials to version control! Store sensitive data encrypted in your database or use Laravel's encryption features.

Usage

Dependency Injection

The recommended way to use the services is through dependency injection:

use CSoellinger\FonWebservices\VatIdCheckWs;
use CSoellinger\FonWebservices\Enum\VatIdCheckLevel;

class InvoiceController extends Controller
{
    public function __construct(
        private VatIdCheckWs $vatIdCheck
    ) {}

    public function store(Request $request)
    {
        $result = $this->vatIdCheck->check(
            $request->input('vat_id'),
            VatIdCheckLevel::ExtendedCheck
        );

        if ($result->valid) {
            // VAT ID is valid - process invoice
        }
    }
}

Using Facades

For quick operations, you can use the provided facades:

use CSoellinger\Laravel\FonWebservices\Facades\FonVatIdCheck;
use CSoellinger\FonWebservices\Enum\VatIdCheckLevel;

$result = FonVatIdCheck::check('ATU12345678', VatIdCheckLevel::SimpleCheck);

if ($result instanceof \CSoellinger\FonWebservices\Model\VatIdCheckValidLevelOne) {
    echo "Company: {$result->name}";
}

Available Facades

• FonSession - Session management
• FonVatIdCheck - VAT ID validation
• FonDataboxDownload - Databox operations
• FonFileUpload - File upload operations
• FonBankDataTransmission - Bank data exchange
• FonQueryDataTransmission - Query submissions

Artisan Commands

Check VAT ID

# Simple check (level 1)
php artisan fon:check-vat ATU12345678

# Extended check (level 2) with address information
php artisan fon:check-vat ATU12345678 --level=2

# JSON output
php artisan fon:check-vat ATU12345678 --json

List Databox Items

# List all items
php artisan fon:list-databox

# Filter by type
php artisan fon:list-databox --type=Veranlagung

# Filter by date range
php artisan fon:list-databox --from=2024-01-01 --to=2024-12-31

# JSON output
php artisan fon:list-databox --json

Usage Examples

In Controllers

use CSoellinger\FonWebservices\VatIdCheckWs;
use CSoellinger\FonWebservices\Enum\VatIdCheckLevel;

class VatController extends Controller
{
    public function __construct(
        private VatIdCheckWs $vatIdCheck
    ) {}

    public function check(Request $request)
    {
        $result = $this->vatIdCheck->check(
            $request->input('vat_id'),
            VatIdCheckLevel::ExtendedCheck
        );

        if ($result instanceof \CSoellinger\FonWebservices\Model\VatIdCheckValidLevelTwo) {
            return response()->json([
                'valid' => true,
                'name' => $result->name,
                'address' => [
                    'street' => $result->street,
                    'zip' => $result->zip,
                    'city' => $result->city,
                ],
            ]);
        }

        return response()->json(['valid' => false]);
    }
}

In Jobs

use CSoellinger\FonWebservices\DataboxDownloadWs;
use CSoellinger\FonWebservices\Enum\DataboxType;

class ProcessDataboxItems implements ShouldQueue
{
    use Queueable, SerializesModels, InteractsWithQueue;

    public function handle(DataboxDownloadWs $databox): void
    {
        $from = new \DateTime('-7 days');
        $to = new \DateTime();

        $items = $databox->get(
            type: DataboxType::All,
            from: $from,
            to: $to
        );

        foreach ($items as $item) {
            // Process each databox item
            $content = $databox->getEntry($item->applkey);
            // Store or process the document...
        }
    }
}

In API Routes

use Illuminate\Support\Facades\Route;
use CSoellinger\Laravel\FonWebservices\Facades\FonVatIdCheck;

Route::get('/api/vat/check/{vatId}', function (string $vatId) {
    $result = FonVatIdCheck::check($vatId);

    return response()->json([
        'vat_id' => $vatId,
        'valid' => $result->valid,
    ]);
});

In Livewire Components

use Livewire\Component;
use CSoellinger\FonWebservices\VatIdCheckWs;

class VatChecker extends Component
{
    public string $vatId = '';
    public ?bool $isValid = null;

    public function checkVat(VatIdCheckWs $vatIdCheck)
    {
        $result = $vatIdCheck->check($this->vatId);
        $this->isValid = $result->valid;
    }

    public function render()
    {
        return view('livewire.vat-checker');
    }
}

Session Management

Session management is handled automatically - services will auto-login when needed. For manual session control:

use CSoellinger\FonWebservices\SessionWs;

class CustomService
{
    public function __construct(
        private SessionWs $session
    ) {}

    public function performOperations(): void
    {
        // Manually login
        $loginResponse = $this->session->login();

        // Perform operations...

        // Manually logout
        $this->session->logout();
    }
}

Configuration

The config/fon-webservices.php file allows you to customize:

• Credentials - FinanzOnline authentication details
• SOAP Options - Configure SOAP client behavior
• Service Bindings - Enable/disable specific services

SOAP Options

These options are passed directly to PHP's SoapClient constructor and control the underlying SOAP behavior:

'soap_options' => [
    'trace' => env('FON_SOAP_TRACE', false),           // Enable request/response tracing (debugging)
    'exceptions' => env('FON_SOAP_EXCEPTIONS', true),  // Throw exceptions on SOAP errors
    'connection_timeout' => env('FON_SOAP_TIMEOUT', 30), // Connection timeout in seconds
    'cache_wsdl' => env('FON_SOAP_CACHE_WSDL', WSDL_CACHE_DISK), // WSDL caching mode
],

You can add any valid SoapClient option here. Common options include compression, user_agent, proxy_host, etc.

Disable Unused Services

To reduce memory usage, you can disable services you don't use:

'services' => [
    'session' => true,
    'vat_id_check' => true,
    'databox_download' => false,  // Disabled
    'file_upload' => false,       // Disabled
    'bank_data_transmission' => false,
    'query_data_transmission' => false,
],
