Send SMS from Laravel with the SendiMessage API

Laravel uses the official PHP SDK: composer require sendimessage/sdk. Bind the client in a service provider with credentials from config/services.php, and every job or listener can inject it.

Dispatch sends from queued jobs rather than inside web requests — the API responds with a queued message either way, and a job keeps checkout and booking flows fast. Incoming webhooks land on a normal Laravel route where you can verify the signature and update your models.

What this integration enables

Order and status notifications
Trigger messages from Laravel when records change state.
Appointment reminders
Scheduled tasks that message customers before a booking.
Support updates
Notify customers as their request moves forward.
Reply handling
Receive incoming replies on a webhook route in the same codebase.

Architecture

How it fits together: Your application event, then Laravel server code, then SendiMessage API, then Managed messaging line, then Webhook events.
  1. Your application eventAn order ships, a booking nears, a ticket updates
  2. Laravel server codeBuilds the request with credentials from the environment
  3. SendiMessage APIPOST /send-message returns the queued message
  4. Managed messaging lineSMS, or iMessage on supported lines and destinations
  5. Webhook eventsDelivery status and incoming replies post back to your endpoint

Example request

Laravel
<?php
// composer require sendimessage/sdk
// config/services.php:
//   'sendimessage' => ['key' => env('SENDIMESSAGE_KEY'), 'secret' => env('SENDIMESSAGE_SECRET')]


use SendImessage\ApiException;
use SendImessage\Client;


// app/Providers/AppServiceProvider.php
$this->app->singleton(Client::class, fn () => new Client(
    apiKey: config('services.sendimessage.key'),
    apiSecret: config('services.sendimessage.secret'),
));


// app/Jobs/SendOrderShippedMessage.php — handle()
public function handle(Client $client): void
{
    try {
        $msg = $client->sendMessage(
            number: $this->order->customer->phone,
            content: "Hi {$this->order->customer->first_name}, your order has shipped.",
        );
        $this->order->update(['message_handle' => $msg['message_handle']]);
    } catch (ApiException $e) {
        report($e); // non-2xx → ApiException with status + body
        $this->release(60);
    }
}

Delivery events and incoming replies

Point a Laravel route at your webhook URL to receive delivery status and incoming replies. Verify the signature header before processing.

webhook event
// "outbound" event → your laravel endpoint
// Verify the SendiMessage-Signature header (t={timestamp},v1=HMAC-SHA256 of
// "{timestamp}.{raw body}", keyed with your webhook secret), then use
// GET /v2/messages/{message_handle} for authoritative state and match it to
// your contact_id in laravel.

Limitations and honest notes

  • iMessage delivery is available on supported messaging lines and destinations. Recipients without iMessage receive SMS when fallback is configured — never assume universal iMessage availability.
  • Messages are accepted asynchronously — the API returns status QUEUED and final status arrives via webhook or the message endpoints.
  • Official SDKs are published for JavaScript/TypeScript (npm: sendimessage), Python (PyPI: sendimessage), PHP (Composer: sendimessage/sdk), and Go (github.com/sendimessage/sendimessage-go). Every SDK is dependency-free and covers the full public API surface.

Security considerations

  • Keep the API key pair in server configuration or environment variables, never in the repository.
  • Verify webhook signatures before trusting delivery or reply events.

Frequently asked questions

Is there an official Laravel package for SendiMessage?
The official SDK for this ecosystem works in any Laravel project — install it with `composer require sendimessage/sdk`. It is dependency-free, covers the full public API, and ships a webhook signature verification helper.
Can Laravel receive message replies?
Yes. Add a route that accepts SendiMessage webhook POSTs; incoming replies arrive as receive events. Correlate them with your records via the message_handle and conversation data in the event.
Should I send inside the request or from a queued job?
From a queued job. The call is fast, but moving it to a job keeps user-facing requests snappy and gives you retries for free via Laravel's queue system.
