Introducing Laravel Sent dm — Multi-Channel Messaging for Laravel

# Introducing laravel-sent-dm

The Laravel ecosystem is built on a culture of expressive, elegant packages.
When I needed to integrate Sent.dm's unified messaging API into a client
project, I went looking for a Laravel adapter.

There wasn't one. So I built it.

## What is Sent.dm?

Sent.dm is a unified messaging API that auto-routes messages across SMS,
WhatsApp, and RCS. It prefers WhatsApp when available and falls back to SMS
— all through a single API call. It handles contact management, templates,
webhooks, number lookup, and multi-profile tenancy.

It is a genuinely well-designed API. It deserved a first-class Laravel
integration.

## What laravel-sent-dm provides

Fluent message builder

use Sujip\SentDm\Facades\Sent;

Sent::to('+61412345678')
->message('Your order has been shipped!')
->send();

Every method returns a clone — the builder is fully immutable.

## Laravel Notifications channel

use Sujip\SentDm\Channels\SentChannel;
use Sujip\SentDm\Messages\SentMessage;

class OrderShipped extends Notification
{
    public function via(object $notifiable): array
    {
        return [SentChannel::class];
    }

    public function toSent(object $notifiable): SentMessage
    {
        return SentMessage::create()
            ->message('Your order has been shipped!');
    }
}

## Queue-backed by default

Every send dispatches a SendSentMessage job. Nothing blocks the request cycle. Retry with exponential backoff is built in. Jobs dispatch after database commit — always.

Webhook engine

The package ships a complete webhook engine:

• Opt-in route via config — never auto-registered
• HMAC-SHA256 signature verification at middleware level
• Replay protection via 5-minute timestamp window
• Typed Laravel Events for all 7 webhook sub-types: message.queued, .routed, .sent, .delivered, .read, .failed, .received

## Bulk dispatch

Sent::bulk($users)->template('promo_template')->dispatch();

Uses Laravel's native job batching under the hood.

HasSentContract trait

class User extends Model
{
    use HasSentContact;
}

$user->sendSentMessage('Hello from Laravel!');

Sent::fake();

// trigger your code

Sent::assertSent(function (SentMessage $message) {
    return $message->getTo() === '+61412345678';
});

composer require sudiptpa/laravel-sent-dm
php artisan sent:install
