🚀 How to Send OTPs, Notifications & DLT SMS in Laravel Using Fast2SMS

SMS is still one of the most reliable channels to reach users instantly. Whether it’s OTP verification, marketing messages, or system alerts, SMS ensures high visibility.

Manually integrating Fast2SMS can be tedious—API payloads, handling templates, and ensuring compliance with DLT. That’s why I built laravel-fast2sms, a package that lets you:

• ✅ Send Quick SMS, OTP, and DLT messages

• ✅ Integrate with queues & scheduling

• ✅ Monitor wallet balance

• ✅ Use as a Laravel Notification channel

In this tutorial, we’ll set up the package, send different SMS types, and explore advanced features like queueing & notifications.

Fast2sms::quick('9999999999', 'Hello, this is a Quick SMS!');
Fast2sms::quick('9999999999', 'नमस्ते! यह एक क्विक एसएमएस है।', SmsLanguage::UNICODE);

2. DLT SMS

use Shakil\Fast2sms\Facades\Fast2sms;

Fast2sms::dlt(
    numbers: '9999999999',
    templateId: 'YOUR_TEMPLATE_ID',
    variablesValues: ['John Doe'],
    senderId: 'YOUR_SENDER_ID'
);

3. OTP SMS

use Shakil\Fast2sms\Facades\Fast2sms;

Fast2sms::otp('9999999999', '123456');

---

4. Fluent Interface

use Shakil\Fast2sms\Facades\Fast2sms;
use Shakil\Fast2sms\Enums\SmsRoute;

Fast2sms::to('9999999999')
    ->route(SmsRoute::DLT)
    ->senderId('YOUR_SENDER_ID')
    ->templateId('YOUR_TEMPLATE_ID')
    ->variables(['John Doe'])
    ->send();

📦 Step 4: Extra Features

✅ Check Wallet Balance

$response = Fast2sms::checkBalance();

if ($response->success()) {
    echo "Wallet Balance: {$response->balance}\n";
    echo "SMS Count: {$response->smsCount}\n";
}

✅ Queueing SMS

Supports Laravel’s job queues:

// Queue a Quick SMS
Fast2sms::quickQueue('9999999999', 'Hello from queue!');

// Queue a DLT SMS
Fast2sms::dltQueue(
    numbers: '9999999999',
    templateId: 'YOUR_TEMPLATE_ID',
    variablesValues: ['John Doe'],
    senderId: 'YOUR_SENDER_ID'
);

// Queue an OTP SMS
Fast2sms::otpQueue('9999999999', '123456');

Advanced Queue Options:

Fast2sms::to('9999999999')
    ->message('Test message')
    ->onConnection('redis')
    ->onQueue('sms')
    ->delay(now()->addMinutes(10))
    ->queue();

✅ Notifications Channel

Integrate SMS into Laravel’s Notification system:

use Illuminate\Notifications\Notification;
use Shakil\Fast2sms\Facades\Fast2sms;
use Shakil\Fast2sms\Enums\SmsRoute;

class LowSmsBalanceNotification extends Notification
{
    public function __construct(
        protected float $balance,
        protected float $threshold
    ) {}

    public function via($notifiable) {
        return ['fast2sms'];
    }

    public function toFast2sms($notifiable) {
        return Fast2sms::to($notifiable->phone)
            ->message("Low SMS balance: {$this->balance}. Threshold: {$this->threshold}.")
            ->route(SmsRoute::QUICK)
            ->send();
    }
}

Usage:

Notification::route('fast2sms', '9999999999')
    ->notify(new LowSmsBalanceNotification(500, 1000));
