Implementing payment gateway in Magento 2

By: Stjepan Udovicic, Last updated: Oct 15, 2019 | Published: Jul 24, 2015

This is a revised article originally written in September 2014 when I started to play with Magento 2 for the first time. Since there were a lot of changes in Magento 2, this article also needed some refreshment. We will glance over the backend, and proceed with the development of a simple module. For this task, I picked up the payment gateway API integration. This relatively simple task will help us demonstrate some key changes in Magento 2.

More precisely, we will be focusing on implementation of Stripe payment gateway. Even though Stripe has a rich set of features, here we will be focusing only on most basic functionalities to get you started with Magento 2 extension development.

NOTE: Magento 2 source code is under constant changes. Although code was tested on early Magento 2.1., it is now outdated. Stay tuned for an update.

Module setup

As you probably already know, a lot has changed in Magento 2, and Module setup and code structure is not an exception. One of the first things you will notice is absence of code pools that we are used to from previous version. Inside the app/code folder we will create our namespace folder. In the end, our file/folder structure would look like this:

Before we proceed, there is one more thing that needs to be taken care of. Stripe comes with its own set of PHP libraries for integration, and they need to be included as well. This, however, should be managed by Composer. If you take a look at composer.json, you will notice require line. By installing this sample extension through composer, Stripe library will be placed under vendor/stripe folder, and will be available through autoloader in our code.

Next big change has been introduced in XML configuration files. Magento 2 has introduced XML scheme for each configuration type that needs to be followed, or otherwise the module will not work. First one that we will create, is module.xml that replaces configuration which was previously placed under app/etc/modules/namespace_modulename.xml. As in magento 1, it is used to declare module and its dependencies:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Inchoo_Stripe" setup_version="1.0.0">
        <sequence>
            <module name="Magento_Sales" />
            <module name="Magento_Payment" />
            <module name="Magento_Directory" />
            <module name="Magento_Config" />
        </sequence>
    </module>
</config>

There are also some changes in other config files, but I’ll let you have fun exploring them yourselves.

Payment implementation

So far, we have created our module file structure, we have created module configuration files and we have integrated our library files. It is now time to proceed with the payment integration.
Anyone who integrated payment gateway in Magento knows the importance of implementing proper admin settings, since the system will handle most of the things automatically. Lets take a look at our etc/adminhtml/system.xml file:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../Magento/Config/etc/system_file.xsd">
    <system>
        <section id="payment">
            <group id="inchoo_stripe" translate="label" type="text" sortOrder="50" showInDefault="1" showInWebsite="1" showInStore="1">

                </field>
                <field id="min_order_total" translate="label" type="text" sortOrder="98" showInDefault="1" showInWebsite="1" showInStore="0">
                    <label>Minimum Order Total</label>
                </field>
                <field id="max_order_total" translate="label" type="text" sortOrder="99" showInDefault="1" showInWebsite="1" showInStore="0">
                    <label>Maximum Order Total</label>
                    <comment>Leave empty to disable limit</comment>
                </field>
            </group>
        </section>
    </system>
</config>

There are only three fields that we need to handle through our code: api_key, min_order_total and max_order_total. As I previously said, Magento will handle the rest through abstract classes by default.

Speaking of classes, it is finally time to implement our Payment class. Due to the nature of Stripe, we will be extending \Magento\Payment\Model\Method\Cc. Besides setting usual config through protected variables, we also have to pass Stripe library to our class to respect dependency injection and testability. Therefore we will begin our class with the following snippet:

namespace Inchoo\Stripe\Model;
 
class Payment extends \Magento\Payment\Model\Method\Cc
{
    const CODE = 'inchoo_stripe';
 
    protected $_code = self::CODE;
 
    protected $_isGateway                   = true;
    protected $_canCapture                  = true;
    protected $_canCapturePartial           = true;
    protected $_canRefund                   = true;
    protected $_canRefundInvoicePartial     = true;
 
    protected $_stripeApi = false;
 
    protected $_countryFactory;
 
    protected $_minAmount = null;
    protected $_maxAmount = null;
    protected $_supportedCurrencyCodes = array('USD');
 
    protected $_debugReplacePrivateDataKeys = ['number', 'exp_month', 'exp_year', 'cvc'];
 
    public function __construct(
        \Magento\Framework\Model\Context $context,
        \Magento\Framework\Registry $registry,
        \Magento\Framework\Api\ExtensionAttributesFactory $extensionFactory,
        \Magento\Framework\Api\AttributeValueFactory $customAttributeFactory,
        \Magento\Payment\Helper\Data $paymentData,
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
        \Magento\Payment\Model\Method\Logger $logger,
        \Magento\Framework\Module\ModuleListInterface $moduleList,
        \Magento\Framework\Stdlib\DateTime\TimezoneInterface $localeDate,
        \Magento\Directory\Model\CountryFactory $countryFactory,
        \Stripe\Stripe $stripe,
        array $data = array()
    ) {
        parent::__construct(
            $context,
            $registry,
            $extensionFactory,
            $customAttributeFactory,
            $paymentData,
            $scopeConfig,
            $logger,
            $moduleList,
            $localeDate,
            null,
            null,
            $data
        );
 
        $this->_countryFactory = $countryFactory;
 
        $this->_stripeApi = $stripe;
        $this->_stripeApi->setApiKey(
            $this->getConfigData('api_key')
        );
 
        $this->_minAmount = $this->getConfigData('min_order_total');
        $this->_maxAmount = $this->getConfigData('max_order_total');
    }

At this point, we have covered almost all differences in module development between Magento 2 and 1. From this point on, most of the code would be the same between those two versions, as far as our Stripe integration is concerned.

Lets proceed with implementation of our most important function, capture():

/**
 * Payment capturing
 *
 * @param \Magento\Payment\Model\InfoInterface $payment
 * @param float $amount
 * @return $this
 * @throws \Magento\Framework\Validator\Exception
 */
public function capture(\Magento\Payment\Model\InfoInterface $payment, $amount)
{
  //throw new \Magento\Framework\Validator\Exception(__('Inside Stripe, throwing donuts :]'));
 
  /** @var \Magento\Sales\Model\Order $order */
  $order = $payment->getOrder();
 
  /** @var \Magento\Sales\Model\Order\Address $billing */
  $billing = $order->getBillingAddress();
 
  try {
      $requestData = [
          'amount'        => $amount * 100,
          'currency'      => strtolower($order->getBaseCurrencyCode()),
          'description'   => sprintf('#%s, %s', $order->getIncrementId(), $order->getCustomerEmail()),
          'card'          => [
              'number'            => $payment->getCcNumber(),
              'exp_month'         => sprintf('%02d',$payment->getCcExpMonth()),
              'exp_year'          => $payment->getCcExpYear(),
              'cvc'               => $payment->getCcCid(),
              'name'              => $billing->getName(),
              'address_line1'     => $billing->getStreetLine(1),
              'address_line2'     => $billing->getStreetLine(2),
              'address_city'      => $billing->getCity(),
              'address_zip'       => $billing->getPostcode(),
              'address_state'     => $billing->getRegion(),
              'address_country'   => $billing->getCountryId(),
              // To get full localized country name, use this instead:
              // 'address_country'   => $this->_countryFactory->create()->loadByCode($billing->getCountryId())->getName(),
          ]
      ];
 
      $charge = \Stripe\Charge::create($requestData);
      $payment
          ->setTransactionId($charge->id)
          ->setIsTransactionClosed(0);
 
  } catch (\Exception $e) {
      $this->debugData(['request' => $requestData, 'exception' => $e->getMessage()]);
      $this->_logger->error(__('Payment capturing error.'));
      throw new \Magento\Framework\Validator\Exception(__('Payment capturing error.'));
  }
 
  return $this;
}

As usual, we will fetch billing information through payment object. Credit card info is than passed to Stripes API which handles the rest. In case of success, we will add this transaction to Magento’s list of transactions, and we are basically done here. It is important to note here, that transaction id should be set to transaction ID received by the payment gateway, since this will be used later on.

Another important feature for payment method is ability to issue a refund from Magento admin. So lets proceed and implement our refund() function:

/**
 * Payment refund
 *
 * @param \Magento\Payment\Model\InfoInterface $payment
 * @param float $amount
 * @return $this
 * @throws \Magento\Framework\Validator\Exception
 */
public function refund(\Magento\Payment\Model\InfoInterface $payment, $amount)
{
  $transactionId = $payment->getParentTransactionId();
 
  try {
      \Stripe\Charge::retrieve($transactionId)->refund();
  } catch (\Exception $e) {
      $this->debugData(['transaction_id' => $transactionId, 'exception' => $e->getMessage()]);
      $this->_logger->error(__('Payment refunding error.'));
      throw new \Magento\Framework\Validator\Exception(__('Payment refunding error.'));
  }
 
  $payment
      ->setTransactionId($transactionId . '-' . \Magento\Sales\Model\Order\Payment\Transaction::TYPE_REFUND)
      ->setParentTransactionId($transactionId)
      ->setIsTransactionClosed(1)
      ->setShouldCloseParentTransaction(1);
 
  return $this;
}

Basically, we are fetching transaction ID, which is then passed to API which handles refund communications. All we need to do here is to properly handle errors and mark transactions. And yes, by handling errors I do mean throwing Exception from inside catch block, in order to notify Magento of an error. Reason for try..catch block in the first place was to sanitize data, since response from server might have sensitive information. This also applies to capture functionality.

In Magento 2, checkout has been rewritten as JS client side application, that is communicating with core system through API. Considering that, PHP part itself is not enough for integration to work. We will proceed by adding two more JS files through layout update XML(check link, it is to large to be listed here). Following files have been added:

Their purpose is to provide configuration for UI component used in checkout. For now, we will leave like that, explaining how this works, requires its own article.

And that is basically it. There may be a few more things to tune up, but our module is ready. Full code can be retrieved at our GIT repository here. An don’t forget to keep an eye on our repository. We plan to implement integration with tokens to avoid sending credit card info to server.

So far we have covered most of the basic things that are required for module development. However, our module is really simple: it lacks any template files, controllers, blocks, composer config, etc. But we will cover all that in our future articles. This is just a warmup to get you started. I hope it was useful, and that you enjoyed reading it.

In case you feel you need some extra help regarding Magento 2, we can offer you a detailed custom report based on our technical audit – feel free to get in touch and see what we can do for you!

Hi Stjepan,
It’s a nice tutorial.
However, if instead of Strip API gateway, I want to send information to some external api url using say POST request, and perform some action based on the response that I get, how can I achieve that?
I am using Magento 2.2.
Thanks

  Hi Sumit,
  There is no extra need to include it any controller or model for this module, just you need add lib in bellow path :-
  ib\internal\Stripe
  and download it from :- https://github.com/stripe/stripe-php/tree/master/lib
  Or if you want to include it any other module so please more describe your question here.

Hello stjepan,
I liked you tutorial and managed to get this extension installed. It comes on frontend and backend. But when I click place order with Stripe selected as payment method I get an error which says “An error occurred on the server. Please try to place order again.”
My magento version is : 2.1.5
I’ve added stripe library.
Have enabled on backend.
Used secret API key genereated on Stripe dashboard.

Hi Stjepan,
thanks for the snippet of code! It is really simple and clear. Me like an other user in this thread have found a problem. I’ve installed this module on magento 2.1 , installed also the library throught composer , got it working in backend and frontend , but when I try to make a payment , I get this error please insert a valid credit card expiration date
I am using the Testing Credit Cards (https://stripe.com/docs/testing) as suggested by you and an expiration date in the future but the problem persists. I am debugging the code and I have discovered that the line
/app/code/Magento/Payment/Model/Method/Cc.php
$info->getCcNumber();
$info->getCcType()
$info->getCcExpYear()
$info->getCcExpMonth()
are empty! I don’t understand the reason.

Hi Stjepan!
I have a question for you, I hope you can help me.
I recent changed to use Magento 2, in the past I had been using osCommerce.
The website only use as a payment method a gateway with a local bank.
This is the map:
osCommerce->Checkout->Payment Method->Using Credit Card
When select a credit card, osCommerce begins a session with the bank, so firts I need to send via WebService the credentials to the bank and the bank return a token session, so when the “Make Payment” button is clicked, the transaction is redirected to a gateway site of the bank with the information of the payment. Then, in this page, when the payment is processed the user client have to click in a “Return” button and go back to the osCommerce site with the result of the transaction and using some variables posted in the returned URL the site display the result of the payment and generate or deny the shopping product.
Do you have an example on how to implement this way in Magento 2?
Thanks for your help.

  That is because extension was not properly installed, you need to install it with composer. Read the instructions here https://github.com/Inchoo/magento2-Inchoo_Stripe
  Otherwise, Stripe library will not be added, and you will receive notification that Stripe/Stripe is missing.
  If you are installing this extension manually(by copy/paste), you need to manually add Stripe library.

  Can you make sure that module is installed via composer, and that your base currency is USD?

Hey,
I am still facing the first most problem with other Payment module examples. I can see payment module in backend but I am not able to see on frontend. I am trying simple offline payment module first. Can someone guide me please how to install module through composer. I made repositories on gitz hub and now trying to package through packagist. but I am getting below error,
” A package with the name magento/project-community-edition already exists.
The vendor is already taken by someone else. You may ask them to add your package and give you maintainership access. The packages already in that vendor namespace can be found at magento

  I had the same problem and noticed the file “Inchoo\Stripe\Model\Payment” is hard coded for USD currency, and I am outside the US.
3. Stjepan Udovicic says:
  Jun 25, 2016 at 15:53
  As luke pointed out, this module is hardcoded to USD currency. Reason behind this is that Stripe works only USD. Please check if this is causing issues for you.

  I Had this same issue and I also faced “Exception error: Invalid block type.”
  Please use composer to install the module completely. Manually placing the stripe folders under Vendor folder wont resolve the issue Because composer adds the class map on vendor/composer/autoload_psr4.php and vendor/composer/autoload_static.php files.
  After installing the module via composer. User setup:upgrade command. The issue will be resolved

Also, plesae check if your base currency is USD.

  Hello Stjepan,
  There is bug in module:
  Refund is not working properly.
  i have solution for that issue.
  you have to pass amount in refund function otherwise it will not working.
  \Stripe\Charge::retrieve($transactionId)->refund(array(
  ‘amount’ => $amount * 100,
  ));

  You have to include stripe library in your magento 2 setup. Or just comment it in payment model for time being.

OK – regarding that error I think I found the problem:
Line 165 of payment.php reads:
```
public function isAvailable($quote = null)......
```
it should read:
```
public function isAvailable(\Magento\Quote\Api\Data\CartInterface $quote = null)......
```

I’m having the same issue mentioned earlier:
Declaration of Inchoo\Stripe\Model\Payment::isAvailable() must be compatible with Magento\Payment\Model\MethodInterface::isAvailable(Magento\Quote\Api\Data\CartInterface $quote = NULL)
I have included the registration.php file:
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Inchoo_Stripe',
__DIR__
);
so I don't think that is causing the issue. It seems to be related to the isAvailable function on line 165 of Payment.php. Any ideas?

  You are missing app/code because you installed magento through composer. You can either create it yourself, or follow guidelines for creating modules through composer. Either way, I will update my post soon.

  Reason behind choosing Stripe is it’s simplicity which was important for educational purposes and since we already had Stripe implementation for Magento 1.x, we decided to stick with it. Regarding the BrainTree, I’m not sure about PayPal’s or Magento’s plans for it..
