When working with Magento 2, sometimes we want to disable Payment methods on the Front page and use it only for Admin. Or, if we want to set more rules for Payment methods to check whether payment method can be used. How we can do that?

We should take a look at the payment abstract class vendor/magento/module-payment/Model/Method/AbstractMethod.php. We can see the method public function isAvailable() - This class will check whether payment method can be used.

   public function isAvailable(\Magento\Quote\Api\Data\CartInterface $quote = null)
        if (!$this->isActive($quote ? $quote->getStoreId() : null)) {
            return false;

        $checkResult = new DataObject();
        $checkResult->setData('is_available', true);

        // for future use in observers
                'result' => $checkResult,
                'method_instance' => $this,
                'quote' => $quote

        return $checkResult->getData('is_available');

As can we see, there is an Observer event, like Magento 1, we can use Observer to disable our Payment Methods. It's Magento 1 way. However, Magento 2 introduces to developers a new way - Plugin.

Create DI on front page: app/code/{Vendor}/{Module Name}/etc/frontend/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    <type name="Magento\Payment\Model\Method\AbstractMethod">
        <plugin name="testValidate"
                type="{Vendor}\{Module Name}\Plugin\Model\Method\Available" sortOrder="1" disabled="false" />

app/code/{Vendor}/{Module Name}/Plugin/Model/Method/Available.php


namespace {Vender}\{Module Name}\Plugin\Model\Method;

class Available
     * @param \Magento\Payment\Model\Method\AbstractMethod $subject
     * @param $result
     * @return bool
     * @throws \Magento\Framework\Exception\LocalizedException
    public function afterIsAvailable(\Magento\Payment\Model\Method\AbstractMethod $subject, $result)

        if($subject->getCode() == 'your payment code, eg: cashondelivery') {
            return false;
        return $result;

$subject is the current Payment Method Model.
