Webhooks

Verification (GET request from Meta)

use RenzoJohnson\WhatsApp\Webhook\Listener;

// Responds to Meta's verification challenge
Listener::verify('YOUR_VERIFY_TOKEN');

Receiving Messages (POST from Meta)

use RenzoJohnson\WhatsApp\Webhook\Listener;
use RenzoJohnson\WhatsApp\Webhook\Notification;

Listener::listen('YOUR_APP_SECRET', function (Notification $notification, array $raw) {
    if ($notification->isText()) {
        echo 'From: ' . $notification->from . "\n";
        echo 'Text: ' . $notification->text . "\n";
    }

    if ($notification->isImage()) {
        echo 'Image ID: ' . $notification->image['id'] . "\n";
    }
});

The listener validates the X-Hub-Signature-256 header using HMAC-SHA256 before processing. Invalid signatures return 401.
