Usage

Sending an Invoice

To send an invoice, you need to create an instance of the FatturaElettronicaClient and call the sendInvoice method.

Example:

<?php

require __DIR__ . '/vendor/autoload.php'; // Adjust the path as necessary

use Brokenice\FatturaElettronica\FatturaElettronicaClient;

// Instantiate the client
$fatturaClient = new FatturaElettronicaClient('your_email@example.com', 'your_password', 'your_signature');

try {
    // Call the sendInvoice method with XML content
    $fatturaClient->sendInvoice('<xml>...</xml>');
    echo 'Invoice sent successfully.';
} catch (Exception $e) {
    // Handle exceptions
    echo 'An error occurred: ' . $e->getMessage();
}

Handling Webhooks

To handle incoming webhooks, you need to create a class extending FatturaElettronicaWebhook and implement the received method.

<?php

namespace Brokenice\Pulse\Http\Controllers\Invoices;

use Brokenice\FatturaElettronica\FatturaElettronicaWebhook as BaseWebhook;
use Brokenice\FatturaElettronica\FileSdI;

class FatturaElettronicaWebhook extends BaseWebhook
{
    public function received(FileSdI $fileSdI): void
    {
        // Handle the received FileSdI
        echo 'File received successfully: ' . $fileSdI;
    }
    
    public function failed(Exception $exception): void
    {
        // Handle webhook failed
    }

    public function signatureSecret(): string
    {
        return 'mysignaure';
    }
}

Define a Route (Laravel Example):

use Brokenice\Pulse\Http\Controllers\Invoices\FatturaElettronicaWebhook;

Route::post('/webhook', [FatturaElettronicaWebhook::class, 'handle']);
