Introducing the Pesapal PHP SDK: Simplify Your Payment Integration

Integrating payment solutions into your PHP applications just got a whole lot easier. We are thrilled to announce the release of our Pesapal PHP SDK, a robust and user-friendly library designed to streamline your interaction with the Pesapal payment gateway.

? Why Pesapal PHP SDK?

Pesapal is a leading payment platform in Africa, offering secure and reliable payment processing for businesses of all sizes. However, integrating Pesapal's API directly can be time-consuming and complex. Our SDK abstracts the intricacies of the API, providing a clean and intuitive interface for developers.

Key Features

• Easy Authentication: Simplifies OAuth authentication with Pesapal.
• Seamless Payment Integration: Quickly initiate payments and handle callbacks.
• Transaction Management: Easily check transaction statuses and process refunds.
• PSR-4 Compliant: Follows PHP-FIG standards for autoloading.
• Extensive Documentation: Well-documented methods and examples to get you started.

Configuration

Initialize the client with your Pesapal credentials:

require 'vendor/autoload.php';

use Katorymnd\PesapalPhpSdk\Api\PesapalClient;
use Katorymnd\PesapalPhpSdk\Config\PesapalConfig;

$consumerKey = 'YOUR_CONSUMER_KEY';
$consumerSecret = 'YOUR_CONSUMER_SECRET';

// Initialize PesapalConfig and PesapalClient
$configPath = __DIR__ . '/../pesapal_dynamic.json';
$config = new PesapalConfig($consumerKey, $consumerSecret, $configPath);
$environment = 'sandbox';
$sslVerify = false; // Enable SSL verification for production


$pesapal = new PesapalClient($config, $environment, $sslVerify);

? Initiating a Payment

Here's how you can initiate a payment with minimal code:

use Katorymnd\PesapalPhpSdk\Utils\PesapalHelpers;

$merchantReference = PesapalHelpers::generateMerchantReference();
$notificationId = 'adbd39cc-a48e-4789-b42b-79ad8deb32df';  // Replace with actual notification ID from IPN registration

// Define the order data as an associative array for the POST request
$paymentDetails= [
    "id" => $merchantReference,
    "currency" => "USD",
    "amount" => 100.00,
    "description" => "Payment for invoice " . $merchantReference,
    "callback_url" => "https://www.example.com/payment-callback",
    "notification_id" => $notificationId,
    "redirect_mode" => "PARENT_WINDOW",
    "cancellation_url" => "https://www.example.com/payment-cancel",
    "billing_address" => [
        "phone_number" => "0700000000",
        "email_address" => "john.doe@example.com",
        "country_code" => "UG",
        "first_name" => "John",
        "middle_name" => "",
        "last_name" => "Doe",
        "line_1" => "123 Example Street",
        "line_2" => "",
        "city" => "Kampala",
        "state" => "KMP",
        "postal_code" => 256
    ]
];

// Obtain a valid access token
    $accessToken = $clientApi->getAccessToken();
    if (!$accessToken) {
        throw new PesapalException('Failed to obtain access token');
    }

// Submit order request to Pesapal
    $response = $clientApi->submitOrderRequest($orderData);

if ($response['status'] === 200 && isset($response['response']['redirect_url'])) {
        $redirectUrl = $response['response']['redirect_url'];
        $orderTrackingId = $response['response']['order_tracking_id'];

} else {
    // Handle errors
    $response['response']['error']
}

---

? Checking Transaction Status

To check the status of a transaction:

use Katorymnd\PesapalPhpSdk\Exceptions\PesapalException;

// Obtain a valid access token
    $accessToken = $clientApi->getAccessToken();
    if (!$accessToken) {
        throw new PesapalException('Failed to obtain access token');
    }

 // Get the transaction status
    $response = $clientApi->getTransactionStatus($orderTrackingId);

if ($response['status'] === 200 && isset($response['response'])) {
        $transactionStatusData = $response['response'];
}

---

? Processing Refunds

Issue a refund with ease:

// Prepare refund data with user-provided values
$refundData = [
    'confirmation_code' => '7323605385336397404011', // the code is received by  checking the transaction status
    'amount' => 50.00,
    'username' => 'John Doe',
    'remarks' => 'Customer Requested Refund'
];

try {
    // Request Refund
    $refundResponse = $clientApi->requestRefund($refundData);

    if ($refundResponse['status'] === 200 && isset($refundResponse['response'])) {
        $refundDataResponse = $refundResponse['response'];

        // Add refund response to the output
        $responseData['refund_response'] = $refundDataResponse;
    } else {
        $errorMessage = $refundResponse['response']['error']['message'] ?? 'Unknown error occurred while requesting a refund.';
        throw new PesapalException($errorMessage);
    }
} catch (PesapalException $e) {
    // Add the error to the response
    $responseData['refund_error'] = [
        'error' => $e->getMessage(),
        'details' => $e->getErrorDetails(),
    ];
}
