I go to Magento 2 Admin > Marketing > Promotions > Cart Price Rules and create a new Rule: Bank Transfer Payment:

Tab Rule Information:

  • Rule Name: Bank Transfer Payment
  • Status: Active
  • Websites: Main Website
  • Customer Groups: select all
  • Coupon: No Coupon
  • Uses per Customer: 0
  • From: blank
  • To: blank
  • Priority: 0
  • Public in RSS Feed: No

Conditions tab:

  • If ALL of these conditions are TRUE :
    • Payment Method is Bank Transfer Payment

Actions Tab:

  • Apply: percent of product price discount
  • Discount Amount: 2
  • Maximum Qty Discount is Applied To: 0
  • Discount Qty Step (Buy X): 0
  • Apply to Shipping Amount: No
  • Discard subsequent rules: No
  • Free Shipping: No
  • Apply the rule only to cart items matching the following conditions (leave blank for all items): nothing

Then I enable Bank Transfer Payment method, go to checkout page, click on Bank Transfer Payment but the Discount Percent Price does not show up in Order Summary.

enter image description here

Please give me an advice. How can make a discount on payment method on Magento 2. For Magento 1, it wroks well.

Thanks very much

This rule doesn't work because Magento 2 doesn't save payment method to quote when you select one. And it also doesn't reload totals when selecting a payment method. And unfortunately, you have to write a custom module to solve the issue.

The new module needs only 4 files to be created:

  1. app/code/Namespace/ModuleName/etc/frontend/routes.xml

    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
        <router id="standard">
            <route id="namespace_modulename" frontName="namespace_modulename">
                <module name="Namespace_ModuleName"/>
            </route>
        </router>
    </config>
    

    This will define a new controller for our module.

  2. app/code/Namespace/ModuleName/Controller/Checkout/ApplyPaymentMethod.php

    <?php
    
    namespace Namespace\ModuleName\Controller\Checkout;
    
    class ApplyPaymentMethod extends \Magento\Framework\App\Action\Action
    {
        /**
         * @var \Magento\Framework\Controller\Result\ForwardFactory
         */
        protected $resultForwardFactory;
    
        /**
         * @var \Magento\Framework\View\LayoutFactory
         */
        protected $layoutFactory;
    
        /**
         * @var \Magento\Checkout\Model\Cart
         */
        protected $cart;
    
        /**
         * @param \Magento\Framework\App\Action\Context $context
         * @param \Magento\Framework\View\LayoutFactory $layoutFactory
         * @param \Magento\Framework\Controller\Result\ForwardFactory $resultForwardFactory
         */
        public function __construct(
            \Magento\Framework\App\Action\Context $context,
            \Magento\Framework\Controller\Result\ForwardFactory $resultForwardFactory,
            \Magento\Framework\View\LayoutFactory $layoutFactory,
            \Magento\Checkout\Model\Cart $cart
        ) {
            $this->resultForwardFactory = $resultForwardFactory;
            $this->layoutFactory = $layoutFactory;
            $this->cart = $cart;
    
            parent::__construct($context);
        }
    
        /**
         * @return \Magento\Framework\Controller\ResultInterface
         */
        public function execute()
        {
            $pMethod = $this->getRequest()->getParam('payment_method');
    
            $quote = $this->cart->getQuote();
    
            $quote->getPayment()->setMethod($pMethod['method']);
    
            $quote->setTotalsCollectedFlag(false);
            $quote->collectTotals();
            $quote->save();
        }
    }
    

    This file creates controller action to save the selected payment method to quote

  3. app/code/Namespace/ModuleName/view/frontend/requirejs-config.js

    var config = {
        map: {
            '*': {
                'Magento_Checkout/js/action/select-payment-method':
                    'Namespace_ModuleName/js/action/select-payment-method'
            }
        }
    };
    

    This file allows to override Magento_Checkout/js/action/select-payment-method file

  4. app/code/Namespace/ModuleName/view/frontend/web/js/action/select-payment-method.js

    define(
        [
            'Magento_Checkout/js/model/quote',
            'Magento_Checkout/js/model/full-screen-loader',
            'jquery',
            'Magento_Checkout/js/action/get-totals',
        ],
        function (quote, fullScreenLoader, jQuery, getTotalsAction) {
            'use strict';
            return function (paymentMethod) {
                quote.paymentMethod(paymentMethod);
    
                fullScreenLoader.startLoader();
    
                jQuery.ajax('/namespace_modulename/checkout/applyPaymentMethod', {
                    data: {payment_method: paymentMethod},
                    complete: function () {
                        getTotalsAction([]);
                        fullScreenLoader.stopLoader();
                    }
                });
    
            }
        }
    );
    

    Sends ajax request to save payment method and reload cart totals.

P.S. Parts of the code were taken from Payment Fee extension for Magento 2.

We just checked the same rule and found that it doesn't work. Using the same conditions, no information about selected chosen method is sent and it is not recorded anywhere until the order is placed and the rule may not work.

enter image description here

Address has no payment method until validation and it gets the payment method from payment quote that doesn't exist because no information has been sent ($model->getQuote()->getPayment()->getMethod() returns null).

enter image description here

We suppose, that this is Magento bug. When you choose a payment method the information should be sent in advance.

On Magento 2.2 i couldn't get MagestyApps answer to work. I needed to add some additional files. Because:

  • Cart Price Rule for Payment Method was removed from admin (as pointed out by DaFunkyAlex);
  • In Magento 2.2 the discount was not being applied on the quote, because the method \Magento\AdvancedSalesRule\Model\Rule\Condition\FilterTextGenerator\Address\PaymentMethod::generateFilterText (actually it falls back to \Magento\AdvancedSalesRule\Model\Rule\Condition\FilterTextGenerator\Address::generateFilterText), was expecting the data payment_method to be set on the quote addresses;
  • Even changing the controller from MagestyApps answer to set payment_method data on the quote addresses, didn't work when the quote became an order, because it don't persist payment_method;

The following module worked out for me (thanks to MagestyApps answer, it was based on top of that):

The solution with the custom module is working.

I just thought that it would be useful info for Magento beginners to know that you also need to add these files to be able to add and enable this module:

(copy from a different module and change files according to your module name and namespace)

app/code/Namespace/ModuleName/composer.js
app/code/Namespace/ModuleName/registration.php
app/code/Namespace/ModuleName/etc/module.xml

then you would be able to run bin/magento setup:upgrade

i created the files and replaced the Namespaces and modulename but i think my files wont be executed.

Maybe an error on my files??

registration.php

<?php

use Magento\Framework\Component\ComponentRegistrar;
ComponentRegistrar::register(
ComponentRegistrar::MODULE,
'Jacor_Checkoutpayment',
__DIR__
);

composer.json

{
"name": "jacor/checkoutpayment",
"autoload": {
    "psr-4": {
        "Jacor\\Checkoutpayment\\": ""
    },
    "files": [
        "registration.php"
    ]
}

}

module.xml

<?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="Jacor_Checkoutpayment" setup_version="1.0.0" />
