Installation and Setup
Step 1: Install the SDK via Composer
Begin by installing the SDK using Composer:
composer require katorymnd/pawa-pay-integration
Step 2: Configure Your API Keys
After installation, you need to configure your API keys provided by pawaPay. You can set them in your application's environment variables.
require_once 'vendor/autoload.php';
use Dotenv\Dotenv;
use Katorymnd\PawaPayIntegration\Api\ApiClient;
use Katorymnd\PawaPayIntegration\Utils\Helpers;
use Katorymnd\PawaPayIntegration\Utils\Validator;
use Katorymnd\PawaPayIntegration\Utils\FailureCodeHelper;
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
use Whoops\Run;
use Whoops\Handler\PrettyPageHandler;
// Initialize Whoops error handler for development
$whoops = new Run();
$whoops->pushHandler(new PrettyPageHandler());
$whoops->register();
// Load the environment variables from the .env file
$dotenv = Dotenv::createImmutable(__DIR__ . '/../');
$dotenv->load();
// Set the environment and SSL verification based on the production status
$environment = getenv('ENVIRONMENT') ?: 'sandbox'; // Default to sandbox if not specified
$sslVerify = $environment === 'production'; // SSL verification true in production
// Dynamically construct the API token key
$apiTokenKey = 'PAWAPAY_' . strtoupper($environment) . '_API_TOKEN';
// Get the API token based on the environment
$apiToken = $_ENV[$apiTokenKey] ?? null;
if (!$apiToken) {
echo json_encode([
'success' => false,
'errorMessage' => 'API token not found for the selected environment.'
]);
exit;
}
// Initialize Monolog for logging
$log = new Logger('pawaPayLogger');
$log->pushHandler(new StreamHandler(__DIR__ . '/../logs/payment_success.log', \Monolog\Level::Info));
$log->pushHandler(new StreamHandler(__DIR__ . '/../logs/payment_failed.log', \Monolog\Level::Error));
// Create a new instance of the API client with SSL verification control
$pawaPayClient = new ApiClient($apiToken, $environment, $sslVerify);
Replace 'YOUR_PAWAPAY_API_KEY' with your actual API key provided by pawaPay in your '.env file.
Using the SDK
Initiating a Payment
To initiate a payment, you can use the initiateDeposit method. Here's how:
// Initialize the API client
$pawaPayClient = new ApiClient($apiToken, $environment, $sslVerify);
// Generate a unique transaction ID (UUID v4)
$transactionId = Helpers::generateUniqueId();
// Define payment details
$amount = '1000'; // Payment amount in KES (Kenyan Shilling)
$currency = 'KES'; // Currency code
$correspondent = 'MPESA_KEN'; // Correspondent ID for the MPESA network
$recipientMsisdn = '254712345678'; // Recipient's phone number
// Custom transaction description
$description = 'Payment for invoice -1234';
// Optional metadata for the transaction
$metadata = [
'order_id' => '1234',
'customer_id' => '5678',
];
// Step 1: Validate the amount
$validatedAmount = Validator::symfonyValidateAmount($amount);
// Step 2: Validate the description
$validatedDescription = Validator::validateStatementDescription($description);
// Step 3: Validate metadata if provided
if (!empty($metadata)) {
Validator::validateMetadataItemCount($metadata);
}
// Step 4: Initiate the payment
$response = $pawaPayClient->initiatePayment(
$transactionId,
$validatedAmount,
$currency,
$correspondent,
$recipientMsisdn,
$validatedDescription,
$metadata
);
// Step 5: Check if the response is successful
if ($response['status'] === 200) {
// Payment was initiated successfully
$log->info('Payment initiated successfully', [
'transactionId' => $transactionId,
'response' => $response['response'],
]);
echo "Payment initiation successful. Transaction ID: $transactionId";
} else {
// Payment initiation failed; handle the error
$log->error('Payment initiation failed', [
'transactionId' => $transactionId,
'error' => $response->getErrorMessage(),
]);
echo "Payment initiation failed. Error: " . $response->getErrorMessage();
}
In this example, we initiate a payment of 1000 KES to a recipient on the MPESA network. We check if the response is successful and handle it accordingly.
Checking Transaction Status
To check the status of a transaction:
// Proceed to check the transaction status
$statusResponse = $pawaPayClient->checkTransactionStatus($transactionId, 'deposit');
if ($statusResponse['status'] === 200) {
$depositInfo = $statusResponse['response'][0]; // Get the deposit info
$depositStatus = $depositInfo['status'];
Replace 'TRANSACTION_ID_RECEIVED' with the transaction ID you received when initiating the payment.
Handling Errors
The SDK is designed to handle errors gracefully. Here's how you might handle exceptions:
try {
$response = $pawaPayClient->initiateDeposit(
$depositId,
$validatedAmount,
$currency,
$mno,
$payerMsisdn,
$validatedDescription,
$metadata
);
// Process response
} catch (Exception $e) {
// Log error details
error_log('Payment initiation error: ' . $e->getMessage());
// Inform the user
echo "An error occurred while processing your payment. Please try again.";
}
Using try-catch blocks allows you to catch exceptions thrown by the SDK and handle them appropriately.
Best Practices
- Secure API Keys: Never expose your API keys in your code repositories. Use environment variables or secure configuration files.
- Validate User Input: Always validate and sanitize user input to prevent injection attacks.
- Error Logging: Implement robust error logging to aid in troubleshooting.
- Transaction Monitoring: Regularly monitor transactions to detect any suspicious activity.
