Features

• Consistent API across all supported languages
• Authenticate with username and API key
• Send SMS to one or more recipients
• Optional sender ID and message priority
• Check account balance
• Comprehensive error handling

Installation

Install via Composer:

composer require pahappa/comms-sdk

Or add to your composer.json:

{
  "require": {
    "pahappa/comms-sdk": "1.0.1"
  }
}

Usage

Basic Authentication

require_once 'vendor/autoload.php';

use CommsSDK\V1\CommsSDK;

// Authenticate with your username and API key
$sdk = CommsSDK::authenticate('your_username', 'your_api_key');

Sending SMS

// Send SMS to a single number
$success = $sdk->sendSMS('256712345678', 'Hello from PHP!');

// Send SMS to multiple numbers
$success = $sdk->sendSMS(['256712345678', '256787654321'], 'Hello to all!');

// Send SMS with custom sender ID and priority
$success = $sdk->sendSMS(
    ['256712345678'],
    'Hello!',
    'MyApp',
    MessagePriority::HIGH
);

// Get full API response
$response = $sdk->querySendSMS(
    ['256712345678'],
    'Hello!',
    'MyApp',
    MessagePriority::HIGHEST
);

Checking Balance

// Get balance as a float
$balance = $sdk->getBalance();
echo "Balance: $balance\n";

// Get full balance response
$response = $sdk->queryBalance();
echo "Status: {$response->status}\n";
echo "Balance: {$response->balance}\n";
echo "Currency: {$response->currency}\n";

Configuration

// Use sandbox environment
CommsSDK::useSandBox();

// Use live server (default)
CommsSDK::useLiveServer();

// Set custom sender ID
$sdk = $sdk->withSenderId('MyCustomSender');

    echo "Authentication error: " . $e->getMessage();
}

try {
