Disable a Payment Method Programmatically in Magento 2

Payment system management can be considered as one of the cores of the Magento 2 store system as a good handling system can help you optimize your sales, profits as well as your efforts.

Sometimes, you will want to restrict specific payment methods based on the customer groups, product/order attributes, shipping parameters, etc. In other words, it’s time when you can programmatically disable a payment method from your Magento 2 backend configuration. For example, with customers who are coming from India, you can deactivate other payment methods and only display the CCAvenue method.

In today’s article, I will show you 2 simple stages to disable payment method programmatically in Magento 2.

2 Steps to Disable a Payment Method Programmically in Magento 2:

• Step 1: Edit config.xml file
• Step 2: Edit Observer.php file

Step 1: Edit config.xml file

To disable the Payment Method Programmatically, firstly, you need to open the config.xml file and then add the following code to that file:

<global>
    ...
    <events>
        <payment_method_is_active>
            <observers>
                <disable_paymentmethod>
                    <class>Vendor_Extension_Model_Observer</class>
                    <method>paymentMethodIsActive</method>
                </disable_paymentmethod>
            </observers>
        </payment_method_is_active>
    </events>
    ...
</global>

Step 2: Edit Observer.php file

In this step, the below code should be added in the Observer.php file

<?php
class Vendor_Extension_Model_Observer {
    public function paymentMethodIsActive(Varien_Event_Observer $observer) {
        $method = $observer->getMethodInstance();
        
        if ($method->getCode() == 'payment_method_code') {
            
            if (condition) {
                $result = $observer->getResult();
                $result->isAvailable = false;
            }
        }
        
    }
}
