Magento – Magento 2 – Custom payment module

extensionsmagento2paymentpayment-gatewaypayment-methods

I'm trying to build a custom Payment module, but it's very hard to get things to work because there's no real documentation yet. There are a few example extensions, but these are all outdated.

What I got working:

The user selects the Payment method
The user can select his bank from a list of dutch banks
After the user presses 'Place order' the user is redirected to the success page

What I cannot figure out to do:

Redirect the user to payment provider after 'Place order' is pressed
I should provide a redirect url to the payment provider where the user is redirected to after payment.
- The ability to fetch the response of the Payment provider and show the success page to the user.

I'm working on this for days now, but I cannot figure out how to do it. Can someone point me in the right direction?

Thanks.

Redirection can be maintained by place order button handler.
For example please refer to Paypal Express checkout integration, here are several components required:

Payment Method form template - where you need to define a click event handler which processes a place order button.

Example app/code/Magento/Paypal/view/frontend/web/template/payment/paypal-express.html

<button class="action primary checkout" type="submit" data-bind="click: placeOrderAction, enable: (getCode() == isChecked())" disabled> <span data-bind="i18n: 'Continue to Gateway'"></span> </button>

View model(renderer) - a model for defined template.

Example app/code/Magento/Paypal/view/frontend/web/js/view/payment/method-renderer/paypal-express-abstract.js

/** Redirect to Gateway */
        placeOrderAction: function () {
                this.selectPaymentMethod(); // save selected payment method in Quote
                setPaymentMethodAction(this.messageContainer);
                return false;
            }
        }

Define setPaymentMethodAction - which will place order and then redirect user to a gateway.

Example app/code/Magento/Paypal/view/frontend/web/js/action/set-payment-method.js

And "The ability to fetch the response of the Payment provider and show the success page to the user.".

The suggestion depends on Payment Gateway a communication pattern between Store and Payment Gateway. But as I understand your case is Redirect to Payment gateway side and then back to store.

This can be gained by defining a response action and route responsible for handling requests from Payment Gateway with redirect logic to Success page

Payment Gateway – Custom Payment Gateway Return URL

Here you can call the api within the action when the user is redirected back to the magento site. Then you can redirected to success page according to payment status. For example if return url is http://yoursite.com/payment/index/success, the success action looks like as shown below :

public function  successAction()
{
    $response = $this->getRequest()->getPost();//get response

   //make another api call here by using curl or whatever

    $this->_redirect('checkout/onepage/success');// redirect success page
}

Magento 2.1.5 – Redirect User to Payment Gateway After Order

This is the observer code to redirect to that payment gateway.

public function execute(\Magento\Framework\Event\Observer $observer)
{ 
    $orderId = $observer->getEvent()->getOrderIds();
    $base_url = $this->_storeManager->getStore()->getBaseUrl();
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $order = $objectManager->create('\Magento\Sales\Model\Order') ->load($orderId[0]);
    $payment = $order->getPayment();


    $method = $payment->getMethodInstance();
    $methodTitle = $method->getTitle();

    $order_data= $order->getData();
    $status = $this->checkoutSession->getLastOrderStatus();

      $increment_id = $order_data['increment_id'];
      $redirect = $objectManager->get('\Magento\Framework\App\Response\Http');
      $redirect->setRedirect($base_url.'custompayment/index/redirect/id/'.$increment_id.'');
      return;

}

My Controller having load layout and render layout only please find my phtml file for that controller it'll auto submit and redirect to payment gateway,

<form action="<?php echo $this->getModeurl();?>" id="custom_payment" method="post"> <input type="hidden" name="action" value="pay" /> <input type="hidden" name="currency" value="<?php echo $this->getOrderdetails('order_currency_code');?>" /> <input type="hidden" name="version" value="2.0" /> <input type="hidden" name="item_name_<?php echo $i ?>" value="<?php echo $item['name'] ?>" /> <input type="hidden" name="item_description_<?php echo $i ?>" value="<?php echo $item['description'] ?>" /> <input type="hidden" name="item_quantity_<?php echo $i ?>" value="<?php echo round($item['quantity']) ?>" /> <input type="hidden" name="item_amount_<?php echo $i ?>" value="<?php echo $item['price'] ?>" /> <input type="hidden" name="merchant" value="<?php echo $this->getMerchant();?>" /> <input type="hidden" name="ref_id" value="<?php echo $this->getOrderdetails('increment_id');?>" /> <input type="hidden" name="delivery_charge" value="<?php echo $this->getOrderdetails('shipping_amount');?>" /> <input type="hidden" name="tax_amount" value="<?php echo $this->getOrderdetails('tax_amount');?>" /> <input type="hidden" name="total_amount" value="<?php echo $this->getOrderdetails('grand_total');?>" /> <input type="hidden" name="str_url" value="" /> <input type="hidden" name="success_url" value="http://127.0.0.1/payment/smoovpay/index/response" /> <input type="hidden" name="cancel_url" value="http://YourWebSite" /> <input type="hidden" name="signature" value="<?php echo $this->getSignatureHash();?>"/> <input type="hidden" name="signature_algorithm" value="sha1" /> <h3>Please wait we are redirecting to Smoovpay.....</h3> </form> <script type="text/javascript"> //<![CDATA[ var paymentform = document.getElementById('custom_payment'); window.onload = paymentform.submit(); //]]> </script>
