README

The MVola Bundle is a Symfony bundle that provides integration with the MVola payment gateway. It offers a convenient way to interact with the MVola API, handle transactions, and manage callbacks.

Features

• Easy integration with Symfony projects
• Handles MVola API authentication
• Provides services for initiating transactions, checking transaction status, and retrieving transaction details
• Includes a callback handler for processing MVola notifications
• Configurable retry mechanism for API calls
• Caching support for authentication tokens

Installation

You can install the MVola Bundle using Composer:

composer require dahromy/mvola-bundle

Configuration

After installing the bundle, you need to configure it in your Symfony application. Add the following to your config/packages/mvola.yaml file:

mvola:
    environment: '%env(MVOLA_ENVIRONMENT)%'
    merchant_number: '%env(MVOLA_MERCHANT_NUMBER)%'
    company_name: '%env(MVOLA_COMPANY_NAME)%'
    consumer_key: '%env(MVOLA_CONSUMER_KEY)%'
    consumer_secret: '%env(MVOLA_CONSUMER_SECRET)%'
    auth_url: '%env(MVOLA_AUTH_URL)%'
    max_retries: 3
    retry_delay: 1000
    cache_ttl: 3600

Make sure to set the corresponding environment variables in your .env file:

MVOLA_ENVIRONMENT=sandbox
MVOLA_CONSUMER_KEY=your_consumer_key_here
MVOLA_CONSUMER_SECRET=your_consumer_secret_here
MVOLA_MERCHANT_NUMBER=your_merchant_number_here
MVOLA_COMPANY_NAME=your_company_name_here
MVOLA_AUTH_URL=https://sandbox.mvola.mg/token

Usage

Initiating a Transaction

To initiate a transaction, you can use the MVolaService:

use DahRomy\MVola\Service\MVolaService;
use DahRomy\MVola\Model\TransactionRequest;

class PaymentController extends AbstractController
{
    private $mvolaService;

    public function __construct(MVolaService $mvolaService)
    {
        $this->mvolaService = $mvolaService;
    }

    public function initiatePayment()
    {
        $transactionRequest = new TransactionRequest();
        $transactionRequest->setAmount(1000)
            ->setCurrency('Ar')
            ->setDescriptionText('Payment for order #123')
            ->setRequestingOrganisationTransactionReference('123456')
            ->setRequestDate(new \DateTime())
            ->setOriginalTransactionReference('123456')
            ->setDebitParty([['key' => 'msisdn', 'value' => '0343500003']])
            ->setCreditParty([['key' => 'msisdn', 'value' => '0343500004']])
            ->setMetadata([
                ['key' => 'partnerName', 'value' => 'Partner Name'],
                ['key' => 'fc', 'value' => 'USD'],
                ['key' => 'amountFc', 'value' => '1']
            ])
            ->setCallbackData([
                'userId' => '123456',
                // ... other callback data
            ]);

        $result = $this->mvolaService->initiateTransaction($transactionRequest);

        // Handle the result
    }
}

Checking Transaction Status

To check the status of a transaction:

$status = $this->mvolaService->getTransactionStatus($serverCorrelationId);

Retrieving Transaction Details

To get the details of a transaction:

$details = $this->mvolaService->getTransactionDetails($transactionId);

Handling Callbacks

The MVola Bundle provides a built-in callback handler that processes incoming callbacks from MVola. To handle these callbacks in your application, follow these steps:

1. Create an event subscriber:

use DahRomy\MVola\Event\MVolaCallbackEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class MVolaCallbackSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents(): array
    {
        return [
            MVolaCallbackEvent::NAME => 'onMVolaCallback',
        ];
    }

    public function onMVolaCallback(MVolaCallbackEvent $event): void
    {
        // Response data from MVola
        $mvolaData = $event->getMVolaData();
        
        // Callback data sent with the transaction request
        $callbackData = $event->getCallbackData();

        // Process the callback data
        // For example, update the transaction status in your database
        // or trigger any necessary business logic
    }
}

1. Register your event subscriber in your services.yaml:

services:
    App\EventSubscriber\MVolaCallbackSubscriber:
        tags:
            - { name: kernel.event_subscriber }

1. Configure the callback URL:

When initiating a transaction, you can include custom callback data:

$transactionRequest = new TransactionRequest();
// ... set other transaction details ...
$transactionRequest->setCallbackData([
    'orderId' => '123456',
    'customerId' => '789',
]);

$result = $this->mvolaService->initiateTransaction($transactionRequest);

The MVola Bundle will automatically handle incoming callbacks at the /mvola/callback endpoint. When a callback is received, it will:

1. Log the received callback data
2. Dispatch a MVolaCallbackEvent

Your event subscriber will then be called to process the callback data according to your application's needs.

You can also customize the callback URL by setting the callbackUrl property in the TransactionRequest object:

$transactionRequest->setCallbackUrl('https://example.com/mvola/callback');

Note: Ensure that your server is configured to accept PUT requests at the callback URL, as MVola sends callbacks using the PUT method.

Error Handling

The bundle throws specific exceptions for different error scenarios. Make sure to catch and handle these exceptions in your application:

• MVolaApiException: For general API errors
• MVolaAuthenticationException: For authentication-related errors
• MVolaValidationException: For validation errors in the request data
• MVolaNetworkException: For network-related errors
• MVolaRateLimitException: For rate limit errors
