Order Processing

Use the following steps to process an order with Cashmos:

I. Create an order:

   $order = new Cashmos\Services\Order\Order();

   // Add items to order

   $order->addItem(
        new Cashmos\Services\Order\Item($name, $unitPrice, $quantity, $description),
   );

   $order->addItem(
       new Cashmos\Services\Order\Item($name2, $unitPrice2, $quantity2, $description2),
   );

   // Set order total.
   // Note that this is the total amount to be charged to the user.
   // Cashmos does not do any item level calculations for total amount.

   $order->setOrderTotal($orderTotal)

   // You can add any custom data to the order which 
   // could be retrieved later after confirmation.
   // This may be information used to identify the customer
   // making the order, etc.
   $customData = [
     'foo' => 'bar'
   ];
   $order->addCustomData($customData);

   // Set return and cancel urls

   $order->returnUrl('https://business.com/paid'); // Url when payment authorization was successful.
   $order->cancelUrl('https://business.com/canceled'); // Url when payment authorization was canceled.

II. Process Order Authorization:

This step allows the user to choose their payment method and provide authorization for the purchase. However, the user's is NOT actually charged. Use the next step to confirm the order and actually charge the user.

    $cashmos = new Cashmos\Cashmos($clientId, $secret);
    $cashmos->process($order);

If the user authorizes the payment, Cashmos will return to the "returnUrl" provided with a payment token as a query parameter (?token="random-token"). This payment token is used to confirm the payment.

III. Confirm Order:
