Configuration description

• reference_id : is the user id
• subscription_key : is the Ocp-Apim-Subscription-Key
• target_environment : can be sanbox or mtncameroon (when you go live)

Don't forget to cache the configurations again with the command php artisan config:cache

Add routes

Route::any('/payment/momo/callback', 'PaymentMomoController@callback')->name('payment.momo.callback');
Route::get('/payment/momo/transaction/{id}', 'PaymentMomoController@getPayment')->name('payment.momo.gettransaction');

Use in controller

First inject the repository class

    private $paymentMomoRepository;
    public function __construct(PaymentMomoRepository $paymentMomoRepository){ #...   

Then consume repository instance to implement your payment logic

    $momoRequestToPayDto = new \Nkaurelien\Momopay\Fluent\MomoRequestToPayDto;
    $momoRequestToPayDto->amount = 100;
    $momoRequestToPayDto->payeeNote = '';
    $momoRequestToPayDto->payerMessage = '';
    $momoRequestToPayDto->externalId = 'my_product_id';
    $momoRequestToPayDto->payer->telephone = '2376XXXXXXXX';
    
    # optional
    $momoRequestToPayDto->currency = 'XAF'; // Use EUR when you are in sandbox mode

    $refId = \Ramsey\Uuid\Uuid::uuid4()->toString();

    $requestToPayResult = $this->paymentMomoRepository->requestToPay($momoRequestToPayDto, $refId);

---

If you prefer the facade instead of injection then do:

    #...
    $requestToPayResult = \Nkaurelien\Momopay\Facades\MomoPay::requestToPay($momoRequestToPayDto, $refId);

Capture events

You can listen to :

• Nkaurelien\Momopay\Events\PaymentFailed is fired after a new verification
• Nkaurelien\Momopay\Events\PaymentSuccessful is fired after a new verification
• Nkaurelien\Momopay\Events\PaymentAccepted (pending) is fired after the success of request to pay or a new verification

Use commands

To verify transactions do

    php artisan momopay:verify-transactions # to verify all transactions
    php artisan momopay:verify-transactions [referenceId] # to verify a specific transaction

Todo

• Create payment events
• Create payment exceptions class
• Create commands for scheduler and cron jobs
• Create transaction table for re-vefication
• Email notification on payment success
• Add orange money payment method
