###STEP 1 : Requesting key
Given you already have cart ready for checkout. We create a veritrans instance
$veritrans = new Veritrans;
$veritrans->settlement_type = '01';
$veritrans->merchant_id = 'T100000000000001000001';
$veritrans->merchant_hash_key = '305e0328a366cbce8e17a385435bb7eb3f0cbcfbfc0f1c3ef56b658';
$veritrans->order_id = 'your_unique_order_id';
$veritrans->session_id = 'your_application_session_id';
$veritrans->gross_amount = '150000';
$veritrans->card_capture_flag = '1';
$veritrans->billing_address_different_with_shipping_address = 1;
$veritrans->required_shipping_address = 0;
dont forget to set your commodity
$commodities = array (
array("COMMODITY_ID" => 'sku1', "COMMODITY_PRICE" => '10000',
"COMMODITY_QTY" => '2',
"COMMODITY_NAME1" => 'Kaos', "COMMODITY_NAME2" => 'T-Shirt'),
array("COMMODITY_ID" => 'sku2', "COMMODITY_PRICE" => '20000',
"COMMODITY_QTY" => '1',
"COMMODITY_NAME1" => 'Celana', "COMMODITY_NAME2" => 'Pants')
);
$veritrans->commodity = $commodities;
request for a key
$key = $veritrans->get_keys();
save order infomation and keys to your database
$data = array(
'order_id' => $order_id,
'session_id' => $this->session->userdata('session_id'),
'amount' => $this->cart->total(),
'token_browser' => $key['token_browser'],
'token_merchant'=> $key['token_merchant']
);
In this sample, we're assuming that we use CodeIgniter ActiveRecord
$this->db->insert('orders', $data);
###STEP 2 : Redirect user to Veritrans payment page
Prepare the FORM to redirect the customer
<html>
<head>
<title>Redirecting to Veritrans</title>
</head>
<body>
<form action="<?= Veritrans::PAYMENT_REDIRECT_URL ?>" method="post" id='form' onSubmit="document.getElementById('submitBtn').disabled=true;">
<input type="hidden" name="MERCHANT_ID" value="<?= $merchant_id ?>" />
<input type="hidden" name="ORDER_ID" value="<?= $order['order_id'] ?>" />
<input type="hidden" name="TOKEN_BROWSER" value="<?= $key['token_browser'] ?>" />
<input id="submitBtn" type="submit" value="Confirm Checkout" />
</form>
<script language="javascript" type="text/javascript">
window.onload = function() {
document.getElementById("form").submit();
}
</script>
</body>
</html>
###STEP 3 : Responding Veritrans Payment Notification After the payment is completed Veritrans will contact Merchant's web server As Merchant, you need to response this query @TODO Validate request from veritrans, make sure it comes from veritrans not from hacker
Create Veritrans Notification instance
$veritrans_notification = new VeritransNotification();
Check if valid
if($order->token_merchant != $veritrans_notification->TOKEN_MERCHANT){
echo "ERR";
$this->db->insert('payment_notifications', array("params" => 'no match'));
exit();
