Magento 2 Payment method for certain Customer groups

Question

Is it possible to choose payment method to certain customer groups? In Magento 1 there are some codes to add payment modules, like that any ways in Magento 2 ? without using plugins?

Answer 1

Let’s create a module. Step 1) Create folders like this.

app/code/Pits/PaymentMethod/etc/
app/code/Pits/PaymentMethod/Observer/

Step 2) Declare your module

app/code/Pits/PaymentMethod/etc/module.xml.

Paste the following code in the above file.

    <?xml version="1.0"?>
    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Pits_PaymentMethod" setup_version="2.0.0" /></config>

Step 4 ) Create registration file. app/code/Pits/PaymentMethod/registration.php Paste the below code.

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Pits_PaymentMethod',
    __DIR__
);

Step 5)Run the below command in the command line

php bin/magento module:enable Pits_PaymentMethod

 php bin/magento setup:upgrade

Step 6)Lets create events.xml file

app/code/Pits/PaymentMethod/etc/events.xml

Paste the below code in it.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="payment_method_is_active">
        <observer name="Pits_PaymentMethod_DisabledPgByCustomergroup" instance="Pits\PaymentMethod\Observer\DisabledPgByCustomergroup" />
    </event>
</config>

Step 7)Lets create observer file

app/code/Pits/PaymentMethod/Observer/DisabledPgByCustomergroup.php

Paste the below code in it.

<?php
namespace Pits\PaymentMethod\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\App\Request\DataPersistorInterface;
use Magento\Framework\App\ObjectManager;
class DisabledPgByCustomergroup implements ObserverInterface
{
    public function __construct(\Psr\Log\LoggerInterface $logger)
    {
        $this->_logger = $logger;
    }
    /**
     *
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
     */
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $result          = $observer->getEvent()->getResult();
        $method_instance = $observer->getEvent()->getMethodInstance();
        $quote           = $observer->getEvent()->getQuote();
        $this->_logger->info($method_instance->getCode());
        /* If Cusomer  group is match then work */
        if (null !== $quote && $quote->getCustomerGroupId() != 4) {
            /* Disable All payment gateway  exclude Your payment Gateway*/
            if ($method_instance->getCode() == 'purchaseorder') {
                $result->setData('is_available', false);
            }
        }
        /*else{
        if($method_instance->getCode() =='purchaseorder'){
        $result->setData('is_available', true);

        }
        }*/
    }
}

Step 8)Run this in command line

php bin/magento setup:upgrade

Answer 2

For this, you need a create module which will fire an observer on event payment_method_is_active .

And on this observer,you can disabled any payment method basis of Customer group .

<?php
namespace Devamitbera\DisabledPgByCustomergroup\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\App\Request\DataPersistorInterface;
use Magento\Framework\App\ObjectManager;

class ObserverforDisabledPaymentgateway implements ObserverInterface
{
    public function __construct() {}

    /**
     *
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
     */
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
      $result = $observer->getEvent()->getResult();
      $method_instance = $observer->getEvent()->getMethodInstance();
      $quote = $observer->getEvent()->getQuote();
      /* If Cusomer  group is match then work */
      if(null !== $quote &&  $quote->getCustomerGroupId() =='YOUR_CUSTOMER_GROUP_ID'  ){
          /* Disable All payment gateway  exclude Your payment Gateway*/
          if($method_instance->getCode() !='YOUR_PAYMENT_METHOD_CODE'){
               $result->isAvailable = false;
          }
      }

    }

}

Note:

Here , i have Disabled all payment payment gateways excluding Your gateways when a particular customer group have order placing
