2.2.a Snap

You can see Snap example here.

Get Snap Token

$params = array(
    'transaction_details' => array(
      'order_id' => rand(),
      'gross_amount' => 10000,
    )
  );

$snapToken = Veritrans_Snap::getSnapToken($params);

Get Snap Token in Yii2

    
    //install library from composer
    //in your controller no need to include anything
    //make sure call class with \Class_name::method()

    public function actionSnapToken() {

        \Veritrans_Config::$serverKey = 'Secret Server Key Goes Here';
        // Set to Development/Sandbox Environment (default). Set to true for Production Environment (accept real transaction).
        \Veritrans_Config::$isProduction = false;
        // Set sanitization on (default)
        \Veritrans_Config::$isSanitized = true;
        // Set 3DS transaction for credit card to true
        \Veritrans_Config::$is3ds = true;

        $complete_request = [
            "transaction_details" => [
                "order_id" => "1234",
                "gross_amount" => 10000
            ]
        ];

        $snap_token = \Veritrans_Snap::getSnapToken($complete_request);
        return ['snap_token' => $snap_token];
  
    }

Initialize Snap JS when customer click pay button

<html>
  <body>
    <button id="pay-button">Pay!</button>
    <pre><div id="result-json">JSON result will appear here after payment:<br></div></pre> 

<!-- TODO: Remove ".sandbox" from script src URL for production environment. Also input your client key in "data-client-key" -->
    <script src="https://app.sandbox.midtrans.com/snap/snap.js" data-client-key="<Set your ClientKey here>"></script>
    <script type="text/javascript">
      document.getElementById('pay-button').onclick = function(){
        // SnapToken acquired from previous step
        snap.pay('<?=$snapToken?>', {
          // Optional
          onSuccess: function(result){
            /* You may add your own js here, this is just example */ document.getElementById('result-json').innerHTML += JSON.stringify(result, null, 2);
          },
          // Optional
          onPending: function(result){
            /* You may add your own js here, this is just example */ document.getElementById('result-json').innerHTML += JSON.stringify(result, null, 2);
          },
          // Optional
          onError: function(result){
            /* You may add your own js here, this is just example */ document.getElementById('result-json').innerHTML += JSON.stringify(result, null, 2);
          }
        });
      };
    </script>
  </body>
</html>

  echo "<pre>";
  var_dump($response);
  echo "</pre>";
}

7. Implement Notification Handler

Refer to this section

2.3 Handle HTTP Notification

Create separated web endpoint (notification url) to receive HTTP POST notification callback/webhook. HTTP notification will be sent whenever transaction status is changed. Example also available here

$notif = new Veritrans_Notification();

$transaction = $notif->transaction_status;
$fraud = $notif->fraud_status;

error_log("Order ID $notif->order_id: "."transaction status = $transaction, fraud staus = $fraud");

  if ($transaction == 'capture') {
    if ($fraud == 'challenge') {
      // TODO Set payment status in merchant's database to 'challenge'
    }
    else if ($fraud == 'accept') {
      // TODO Set payment status in merchant's database to 'success'
    }
  }
  else if ($transaction == 'cancel') {
    if ($fraud == 'challenge') {
      // TODO Set payment status in merchant's database to 'failure'
    }
    else if ($fraud == 'accept') {
      // TODO Set payment status in merchant's database to 'failure'
    }
  }
  else if ($transaction == 'deny') {
      // TODO Set payment status in merchant's database to 'failure'
  }
}

2.4 Process Transaction

Get Transaction Status

$status = Veritrans_Transaction::status($orderId);
var_dump($status);

Approve Transaction

If transaction fraud_status == CHALLENGE, you can approve the transaction from Merchant Dashboard, or API :

$approve = Veritrans_Transaction::approve($orderId);
var_dump($approve);

Cancel Transaction

You can Cancel transaction with fraud_status == CHALLENGE, or credit card transaction with transaction_status == CAPTURE (before it become SETTLEMENT)

$cancel = Veritrans_Transaction::cancel($orderId);
var_dump($cancel);

Expire Transaction

You can Expire transaction with transaction_status == PENDING (before it become SETTLEMENT or EXPIRE)

$cancel = Veritrans_Transaction::cancel($orderId);
var_dump($cancel);

Contributing

Developing e-commerce plug-ins

There are several guides that must be taken care of when you develop new plugins.

  1. Handling currency other than IDR. Veritrans v1 and v2 currently accepts payments in Indonesian Rupiah only. As a corrolary, there is a validation on the server to check whether the item prices are in integer or not. As much as you are tempted to round-off the price, DO NOT do that! Always prepare when your system uses currencies other than IDR, convert them to IDR accordingly, and only round the price AFTER that.

  2. Consider using the auto-sanitization feature.
