Laravel DigitalOcean API - Get newly created droplet login information

I'm new to the DigitalOcean API and I'm trying to get something done. When a user completes a step program, a new droplet will be created in the code. Now I need the login credentials for this newly created droplet. These are automatically sent via Email. I need these so I can connect with the created droplet and perform commands on it. How can I achieve the above? I tried doing $droplet->user_data() but unfortunately that does not work.

Code

public function store(Request $request, $id)
{

    $order = Order::find($id);

    $payment = Mollie::api()->payments()->get($order->mollie_transaction_id);

    $mainsettings = Session::get('main_settings');

    $webshop = $this->_webshopRepository->createWebshop();

    $addressData = [$mainsettings['region'], $mainsettings['city'], $mainsettings['postal_code'], $mainsettings['street_name'], $mainsettings['house_number']];
    $adres = $this->_addressRepository->createAddress($addressData);

    $mainsettingData = [$adres->id, $webshop->id, $mainsettings['store_name'], $mainsettings['store_tel'], $mainsettings['store_hoo'], $mainsettings['vat_number']];
    $mainsetting = $this->_mainsettingRepository->createMainSetting($mainsettingData);

    $images = DigitalOcean::image()->getAll(['private' => true]);
    $storeName = str_replace(' ', '-', $mainsetting['store_name']);

    // Here is where I am creating the droplet

    $droplet = DigitalOcean::droplet()->create($storeName, 'ams3', 's-1vcpu-1gb', $images[0]->id);

    $droplet->user_data();

    $commands = ["cd /home/", "rmdir test"];
    \SSH::run($commands, function($line){
        \Log::debug($line);
    });

    session()->forget('main_settings');
    session()->forget('chosen_theme');
    session()->forget('chosen_plugins');

    return $this->show($order, $payment);

}
