📨 Swissecho — Laravel Multi-Channel Notification Package

What is Swissecho?

Swissecho is a Laravel package that provides a unified, fluent API for sending messages across multiple channels and multiple gateway providers. Instead of writing separate integration code for each provider, you configure them all in one place and switch between them with a single method call.

Supported Channels (Routes)

Channel	Description	Supported Gateways
SMS	Traditional text messages	Termii, RouteMobile, SmsBroadcast (AU), TNZ (NZ), NigerianBulkSMS, Montnets, Wirepick
Voice	Voice OTP / voice calls	Termii, Textng.xyz
WhatsApp	WhatsApp messaging	KudiSMS
Slack	Slack notifications	Incoming Webhook, Bot Token (`chat.postMessage`)
Telegram	Telegram Bot messages	Telegram Bot API (`sendMessage`)

Key Features

🔀 Multi-gateway — Switch SMS providers per-request or per-country
🌍 Geo-routing (Places) — Automatically route messages to the correct gateway based on the recipient's country
🧪 Mock mode — In development, messages are logged to file or sent to email instead of hitting live APIs
🔔 Laravel Notification integration — Use it as a standard Laravel notification channel
⚡ Direct sending — Send messages without creating a Notification class
📣 Events — An AfterSend event is dispatched after every message, giving you full insight into requests and responses
🪝 Webhooks — Built-in webhook handling for provider callbacks (e.g., delivery reports)

Requirements

Dependency	Supported Versions
PHP	^8.1
Laravel	11.x, 12.x, 13.x

Installation

composer require tekkenking/swissecho

The package auto-discovers itself via Laravel's package auto-discovery — no manual registration needed.

The Config File

You can publish and customize the full config at config/swissecho.php. The most important sections are:

Key	Purpose
`live`	`true` = send real messages; `false` = mock mode
`sender`	Default sender ID/name
`fake`	Mock strategy: "log" or "mail"
`route`	Default channel: `sms`, `voice`, `whatsapp`, `slack`, or `telegram`
`routes_options`	Per-channel gateway definitions and geo-routing rules

Geo-Routing with `places`

Each route (SMS, voice, WhatsApp) has a places map that automatically picks the right gateway based on the recipient's country:

'sms' => [
    'gateway_options' => [ /* ... */ ],
    'places' => [
        'nga' => [                          // Nigeria
            'gateway'   => 'nigerianbulksms',
            'phonecode' => '234'
        ],
        'gha' => [                          // Ghana
            'gateway'   => 'wirepick',
            'phonecode' => '233'
        ],
        'aus' => [                          // Australia
            'gateway'   => 'smsbroadcast',
            'phonecode' => '61'
        ],
        'nzl' => [                          // New Zealand
            'gateway'   => 'tnz',
            'phonecode' => '64'
        ],
    ]
],

The phone code is automatically prepended to phone numbers (stripping leading 0 or +).

🔌 Adding a Custom SMS Gateway

Swissecho is designed to be easily extensible. If you need a gateway that isn't built in, you can wire up your own in three steps — no need to touch the package source at all.

Step 1: Create Your Gateway Class

Create a folder anywhere in your project (e.g., app/Sms/Gateways/MyProvider/) and add a class inside it. The class must:

Extend Tekkenking\Swissecho\Routes\Sms\Gateways\BaseGateway
Implement two methods: init() and send()

<?php

namespace App\Sms\Gateways\MyProvider;

use Tekkenking\Swissecho\Routes\Sms\Gateways\BaseGateway;

class MyProvider extends BaseGateway
{
    /**
     * Build and return the request payload that will be passed to send().
     *
     * Available properties (populated by BaseGateway from the message builder):
     *   $this->to      — array of recipient phone numbers
     *   $this->sender  — sender ID / name
     *   $this->body    — the SMS message text
     *   $this->config  — your gateway's config block from config/swissecho.php
     *
     * @return mixed  Any value you like — it will be passed directly to send().
     *                Typically a URL string, an array, or a Guzzle request object.
     */
    public function init(): mixed
    {
        // Example: build a query-string URL
        $url  = $this->config['url'];
        $url .= '?api_key='   . $this->config['auth']['api_key'];
        $url .= '&from='      . $this->sender;
        $url .= '&to='        . implode(',', $this->to);
        $url .= '&message='   . urlencode($this->body);

        return $url;
    }

    /**
     * Receive the value returned by init(), make the HTTP call,
     * and return a configured cURL handle.
     *
     * @param  mixed $data  Whatever init() returned.
     * @return \CurlHandle|bool  A ready-to-execute cURL handle.
     *                           Swissecho calls curl_exec() on it automatically.
     */
    public function send($data): \CurlHandle|bool
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // ⚠️ Only disable in local/testing environments; keep true in production
        return $ch;
    }
}

How it works under the hood: after send() returns the cURL handle, Swissecho's SwissechoGatewayTrait::execCurl() calls curl_exec(), collects the response, formats it, and fires the AfterSend event.

Step 2: Register the Gateway in the Config

Open config/swissecho.php and add your gateway to the routes_options.sms.gateway_options array:

use App\Sms\Gateways\MyProvider\MyProvider; // ← import your class

'routes_options' => [
    'sms' => [
        'gateway_options' => [

            // ... existing gateways ...

            'myprovider' => [               // ← the key becomes the gateway "name"
                'class'  => MyProvider::class,
                'url'    => env('MYPROVIDER_URL'),
                'auth'   => [
                    'api_key' => env('MYPROVIDER_API_KEY'),
                ],
                // add any other keys your gateway needs — they will all be
                // available inside your class as $this->config['...']
            ],
        ],
    ],
],

Add the corresponding values to your .env:

MYPROVIDER_URL=https://api.myprovider.com/send
MYPROVIDER_API_KEY=your_api_key_here

Step 3: Use Your Gateway

That's it — your gateway is now a first-class citizen in Swissecho. Use it exactly like any built-in gateway:

// Direct / fluent sending
swissecho()->gateway('myprovider')->quick('2348012345678', 'Hello!');

// Or inside a route callback
swissecho()->route('sms', function ($ms) {
    return $ms->to('2348012345678')
              ->content('Your OTP is 9988')
              ->gateway('myprovider');
})->go();

// Or inside a Laravel Notification
public function toSms($notifiable): SwissechoMessage
{
    return (new SwissechoMessage())
        ->line('Your order has shipped!')
        ->gateway('myprovider');
}

You can also map it to a country in places for automatic geo-routing:

'places' => [
    'zaf' => [                  // South Africa, for example
        'gateway'   => 'myprovider',
        'phonecode' => '27',
    ],
],

`BaseGateway` Quick Reference

Member	Type	Description
`$this->to`	`array`	Recipient phone numbers
`$this->sender`	`string`	Sender ID / name
`$this->body`	`string`	The message text
`$this->config`	`array`	Your gateway's full config block from `swissecho.php`
`init(): mixed`	abstract method	Build the request payload; return value is passed to `send()`
`send($data): \CurlHandle	bool`	abstract method

Usage

Swissecho can be used in two ways: directly (without a Notification class), or through Laravel's notification system.

Access Methods

You have three ways to get a Swissecho instance:

// 1. Global helper function
swissecho()

// 2. Laravel Facade
Swissecho::

// 3. From the container
app('swissecho')

A) Direct Sending (Without Notification Classes)

Quick Send — One Liner

The simplest way to send a message. Uses the default route and default gateway from config:

swissecho()->quick('2348012345678', 'Your OTP code is 1234');

Quick Send with a Specific Gateway

swissecho()->gateway('vonage')->quick('2348012345678', 'Your OTP code is 1234');

Fluent Builder — Full Control

swissecho()->route('sms', function ($ms) {
    return $ms->to('2348012345678, 2348098765432')  // comma-separated recipients
              ->content('Your order has been shipped!')
              ->line('Track it at https://example.com/track');  // appends a new line
              // ->gateway('routemobile')   // override gateway inside callback
              // ->sender('MyBrand')        // override sender inside callback
})
->to('2348011111111')       // optional: additional/fallback recipient
->sender('MyApp')           // optional: override sender
->gateway('termii')         // optional: override gateway
->go();                     // 🚀 sends the message

Property-Based Sending

You can also set properties directly on the Swissecho instance:

$sw = swissecho();
$sw->gateway('termii');
$sw->to = '2348012345678';
$sw->sender = 'MyApp';
$sw->message = 'The world is a beautiful place created by GOD';
$sw->go();

Sending via WhatsApp

swissecho()->route('whatsapp', function ($ms) {
    return $ms->to('2348012345678')
              ->content('Hello from WhatsApp!');
})->go();

Sending via Slack

Incoming Webhook mode (set SLACK_WEBHOOK_URL — no recipient needed):

swissecho()->message('Deployment finished ✅')
    ->route('slack')
    ->go();

Bot Token mode (set SLACK_BOT_TOKEN — channel is required):

swissecho()->message('Hello team!')
    ->to('#alerts')
    ->route('slack')
    ->go();

Sending via Telegram

swissecho()->message('Server restarted 🔄')
    ->to('123456789')   // your Telegram chat_id
    ->route('telegram')
    ->go();

Sending via Voice Call

swissecho()->route('voice', function ($ms) {
    return $ms->to('2348012345678')
              ->content('Your OTP is 5 6 7 8');
})->gateway('termii')->go();

B) Laravel Notification Channel Integration

Swissecho integrates with Laravel's built-in notification system. Create a notification class and define a toSms (or toVoice, toWhatsapp, toSlack) method:

Step 1: Create the Notification

<?php

namespace App\Notifications;

use Illuminate\Notifications\Notification;
use Tekkenking\Swissecho\SwissechoMessage;

class OrderShipped extends Notification
{
    /**
     * The delivery channels.
     */
    public function via($notifiable): array
    {
        return ['swissecho'];
    }

    /**
     * (Optional) Tell Swissecho which routes to use.
     * If omitted, defaults to ['sms', 'slack', 'whatsapp', 'telegram'].
     */
    public function swissechoRoutes($notifiable): array
    {
        return ['sms'];
    }

    /**
     * Build the SMS message.
     * Method name follows the pattern: to{Route}  →  toSms, toVoice, toWhatsapp, toSlack, toTelegram
     */
    public function toSms($notifiable): SwissechoMessage
    {
        return (new SwissechoMessage())
            ->line('Hi ' . $notifiable->name . '!')
            ->line('Your order has been shipped.')
            ->sender('MyStore');
    }
}

Step 2: Make Your User Model "Notifiable"

Swissecho pulls the phone number from the notifiable model. Implement one of these:

class User extends Authenticatable
{
    use Notifiable;

    /**
     * Option A: Have a `phone` attribute on the model (e.g. column in DB).
     * Swissecho checks $notifiable->phone automatically.
     */

    /**
     * Option B: Define this method for custom logic.
     */
    public function routeNotificationPhone(): string
    {
        return $this->mobile_number;
    }

    /**
     * (Optional) Slack channel for this user.
     */
    public function routeNotificationSlackChannel(): string
    {
        return '#team-alerts';
    }

    /**
     * (Optional) Telegram chat_id for this user.
     */
    public function routeNotificationTelegramChatId(): string
    {
        return $this->telegram_chat_id;
    }

    /**
     * (Optional) Tell Swissecho the recipient's country for geo-routing.
     * Return a 3-letter ISO code matching a key in config places.
     */
    public function routeNotificationPlace(): string
    {
        return 'nga'; // Nigeria
    }
}

Step 3: Send the Notification

$user->notify(new OrderShipped());

SwissechoMessage API Reference

The SwissechoMessage class is the message builder used in callbacks and notification methods:

Method	Description	Example
`->line($text)`	Appends a line of text to the message body. Multiple calls add new lines.	`->line('Hello')`
`->content($text)`	Alias for `line()`.	`->content('Hello')`
`->to($recipient)`	Sets the recipient(s). Accepts a string or comma-separated list.	`->to('234801..., 234809...')`
`->sender($name)`	Sets the sender ID (max 10 characters).	`->sender('MyApp')`
`->from($name)`	Alias for `sender()`.	`->from('MyApp')`
`->gateway($name)`	Overrides the gateway for this message.	`->gateway('termii')`
`->place($code)`	Sets the country/place code (e.g., 'nga'). Overrides auto-detection.	`->place('nga')`
`->phonecode($code)`	Manually sets the phone country code (e.g., '234').	`->phonecode('234')`
`->identifier($id)`	Attaches an identifier (e.g., user ID) to the message for tracking.	`->identifier($user->id)`
`->route($name)`	Sets the route/channel on the message itself.	`->route('sms')`

Mock Mode (Development & Testing)

When SWISSECHO_ENABLED=false (the default), no real API calls are made. Instead, messages are captured by the mock system.

Mock via Log (Default)

Messages are written to storage/logs/swissecho_mock.log:

SWISSECHO_FAKE=log

The log includes: sender, recipient, message body, route, gateway, gateway class, country, and phone code.

Mock via Email

Messages are emailed to the configured address:

SWISSECHO_FAKE=mail
SWISSECHO_FAKE_MAIL=developer@example.com

Events

After every message send (including mock sends), Swissecho dispatches the AfterSend event:

Tekkenking\Swissecho\Events\AfterSend

Event Properties

Property	Type	Description
`$insightPayload`	`array`	Contains `request` (the payload sent to the gateway) and `response` (raw gateway response)
`$formattedResponse`	`array`	Structured response with `status`, `partner_response`, `from`, `to`, `body`, `route`, `gateway`, `identifier`, `timestamp`
`$identifier`	`mixed`	The identifier attached to the message (e.g., user ID)

Listening to the Event

// app/Providers/EventServiceProvider.php
protected $listen = [
    \Tekkenking\Swissecho\Events\AfterSend::class => [
        \App\Listeners\LogSmsDelivery::class,
    ],
];

<?php
// app/Listeners/LogSmsDelivery.php

namespace App\Listeners;

use Tekkenking\Swissecho\Events\AfterSend;

class LogSmsDelivery
{
    public function handle(AfterSend $event): void
    {
        // $event->formattedResponse['status']   — true/false
        // $event->formattedResponse['to']       — recipient array
        // $event->formattedResponse['gateway']  — which gateway was used
        // $event->insightPayload['request']     — raw request payload
        // $event->insightPayload['response']    — raw response from provider

        logger()->info('SMS sent', $event->formattedResponse);
    }
}

Webhooks

Swissecho includes a built-in webhook handler for receiving delivery reports or callbacks from gateway providers. The webhook system validates a secret key and routes the request to the appropriate gateway handler.

Configure webhooks per gateway in config/swissecho.php:

'{$gateway}' => [
    // ...
    'webhook' => [
        'secret' => env('TERMI_WEBHOOK_SECRET', 'your-secret-here'),
        'handle' => 'webhook'   // method name on the gateway class
    ]
],

Helper Functions

Swissecho provides global helper functions for phone number manipulation:

Function	Description
`swissecho()`	Returns the Swissecho singleton instance
`addCountryCodeToPhoneNumber($phone, $code)`	Prepends a country code (e.g., '234') to a phone number, stripping leading `0` or `+`
`removeCountryCodeFromPhoneNumber($phone, $code)`	Strips a country code prefix from a phone number
`convertPhoneNumberToArray($phone)`	Splits a comma-separated phone string into an array

Examples

addCountryCodeToPhoneNumber('08012345678', '234');
// Returns: "2348012345678"

removeCountryCodeFromPhoneNumber('2348012345678', '234');
// Returns: "8012345678"

convertPhoneNumberToArray('2348012345678, 2348098765432');
// Returns: ["2348012345678", "2348098765432"]
