Magento – Magento 2 programmatically online refund

magento-2.1magento2refundsales-ordertransaction

I'm trying to make online refund using this method:

// \Magento\Sales\Model\Order\Invoice $_invoiceModel
// \Magento\Sales\Model\Order\CreditmemoFactory $_creditmemoFactory
// \Magento\Sales\Model\Service\CreditmemoService $_creditmemoService

$invoiceobj = $this->_invoiceModel->loadByIncrementId('000000073');
$creditmemoObject = $this->_creditmemoFactory->createByOrder($order);
$creditmemoObject->setInvoice($invoiceobj);
$this->_creditmemoService->refund($creditmemoObject);

And I'm receiving following error:

We don't have enough information to save the parent transaction ID.

Try the service layer. This interface was added in 2.1.3 for exactly this purpose:

\Magento\Sales\Api\RefundInvoiceInterface

// Inject \Magento\Sales\Api\RefundInvoiceInterface $invoiceRefunder
$invoiceRefunder->execute(
    123, // Invoice ID (NOTE: not increment ID)
    [], // Items array (default all)
    true // Online refund--send to payment gateway
);

There are several additional optional arguments for notifying the customer and adding a comment.

If you're curious, you can find the implementation here: https://github.com/magento/magento2/blob/2.1-develop/app/code/Magento/Sales/Model/RefundInvoice.php#L127

Magento – Partial refund option missing (Qty to Refund)

Here is the code that controls weather 'Qty to Refund' option is available.

public function canEditQty()
{
    if ($this->getCreditmemo()->getOrder()->getPayment()->canRefund()) {
        return $this->getCreditmemo()->getOrder()->getPayment()->canRefundPartialPerInvoice();
    }
    return true;
}

So payment method model must either declare:

$_canRefund = false;

$_canRefund = true;
$_canRefundInvoicePartial = true;

Another thing to keep in mind is that availability of this option also depends on the type of the payment gateway. This option is always supported for offline, but sometimes won't be for online payment gateways. Reason for this is that sometimes they do not support partial refunds, or they were implemented poorly in Magento.

In case that refund is done online, payment method must implement following methods:

processBeforeRefund (optional)
refund
processCreditmemo (optional)

Magento 1.9 – Online Refunding with Custom Payment Method

You can only do refunds online if you've captured the invoice online (e.g via a payment gateway). Since this is not the case you only can do offline refunds.
