## Plain PHP cURL

```php theme={null}
<?php
$payload = [
  "to" => "+255700000000",
  "text" => "Your booking is confirmed.",
  "channels" => ["whatsapp_qr", "sms"],
  "deliveryMode" => "fallback",
  "whatsappFrom" => "447405993704",
  "sender" => "APPROVED"
];

$baseUrl = getenv("KARFLOWS_BASE_URL") ?: "https://your-karflows-domain.com";
$ch = curl_init($baseUrl . "/api/omni/send");
curl_setopt_array($ch, [
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_POST => true,
  CURLOPT_HTTPHEADER => [
    "Authorization: Bearer " . getenv("KARFLOWS_UNIFIED_TOKEN"),
    "Content-Type: application/json"
  ],
  CURLOPT_POSTFIELDS => json_encode($payload),
]);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
```

## Laravel HTTP client

```php theme={null}
use Illuminate\Support\Facades\Http;

$response = Http::withToken(config('services.karflows.unified_token'))
    ->post(config('services.karflows.base_url') . '/api/omni/send', [
        'to' => '+255700000000',
        'text' => 'Your order has been received.',
        'channels' => ['whatsapp_qr', 'sms'],
        'deliveryMode' => 'fallback',
        'whatsappFrom' => '447405993704',
        'sender' => 'APPROVED',
    ]);

return $response->json();
