According to the latest research, e-commerce’s share of sales continues to steadily grow. This year, online sales represented around 15% growth in comparison to last year’s figures. Currently, online sales are forecasted to continue to grow up to 17% by 2022. Below, we reveal some secrets about something at the very heart of e-commerce. Payment gateways: how to choose the best one, and how to add a payment gateway to a website.

What is an Online Payment Gateway and How Does It Work?

A payment gateway is merely the software intended to deliver transactional data to the acquiring bank and retrieving responses from the issuing bank on whether a transaction was approved or declined. Essentially, payment gateways facilitate communication between banks.

As for the working principles of a payment gateway – here’s what is going on right after a user clicks the “Order” button:

  • 1. The customer’s browser encrypts the data and sends it to the merchant’s server, which transfers it to the payment gateway.
  • 2. The payment gateway forwards details to the merchant’s bank payment processor, which sends data to the card association, and the latter then transmits the transaction to the card-issuing bank.
  • 3. The card-issuing bank receives the authorization request and sends the processor a response code that denotes if it is approved or denied.
  • 4. The processor forwards the response code to the payment gateway, which forwards it to the website. Next, it goes to the cardholder and merchant.
  • 5. The merchant then fulfills the order and submits all previously approved authorizations in a so-called “batch” to the acquiring bank at the end of the day, for settlement via its processor.
  • 6. The acquiring bank makes the batch settlement request of the credit issuer, which makes a settlement payment to the acquiring bank. The acquiring bank subsequently deposits the total of the approved funds to the merchant’s nominated account. Typically, the entire process from A to Z takes 3 days.
How does a payment gateway work

Every merchant falls under the PCI DSS, a government regulation standard containing a series of security requirements that every merchant must follow to be in compliance. However, the majority of e-commerce websites don’t store credit card data. Rather, they use third-party payment service providers like PayPal or Stripe to handle card information more securely. The merchants still need to be PCI DSS compliant, but the requirements aren’t as numerous compared to merchants who store credit card data.

Requirements for an E-commerce Payment Gateway

How to choose a payment gateway for an e-commerce website
  • Economic. We’re certainly not saying to just blindly pick the cheapest one, but make sure it’s competitive.
  • Secure. Payment gateways should have PCI DSS certification in the event you are going to accept credit cards.
  • Responsible. If your system is scheduled to experience any downtime for updates, etc., make sure notification is repeatedly given in advance via different channels, such as your website and social media accounts, so your customers are not caught off guard.

E-commerce Payment Gateway Integration Process

Depending on the e-commerce platform you use to run your online business, you can use a wide variety of off-the-shelf plugins and extensions offered by your platform. They will enable you to integrate your store with every payment gateway mentioned in this article.

Website integration with a payment gateway starts with registering a bank account, which will then be attached to the gateway. Make sure your registered bank account is authorized to accept funds, since regular bank accounts may not work for this. Right after your merchant account is approved, it’s time to choose your gateway.

After you have selected your gateway, you’ll follow a specific setup procedure in order to add it to your store. Depending on the payment gateway you’ve chosen, it can be pretty simple via plugin or add-on, or it may require some custom development. Right after website integration with the payment gateway, we recommend that you turn to a QA engineer to ensure the gateway works properly. You should also check the PCI DSS compliance to be 100% sure the gateway is fully secure and doesn’t display credit card information.

Finally, after the payment gateway integration process is completed successfully, you are fully ready to use it, accept payments from customers, and mark their orders as ready to fulfill on your end.

Payment Gateways From Scratch?

After you’ve reviewed the most popular existing solutions for payments in the world of e-commerce, you may instead wonder about developing your own payment gateway for your e-commerce site. And, judiciously, you’d like to learn more details about the process.

Custom payment gateway development is a pretty complex, not to mention pricey, process. In general, if we look at full-stack payment gateway development, it takes from $100,000, and that just the price for development. This is just the price for development since there are so many facets to cover. And each of these aspects means an additional item of expenditure for you! Let’s look at some of the necessary steps:

  • Get registered as a payment gateway provider with the card network through an acquiring bank.
  • Set up a merchant management system.
  • Set up a merchant funding system.

And the most crucial one – obtain PCI certifications. On average, this step is roughly estimated to run about $15,000.

So, as you can see, in addition to the complexity of the development itself, custom payment gateway development in general is not a piece of cake. With this in mind, we’d recommend you to consider the already existing solutions and build your own system on top of it.

Our Experience in Payment Gateway Integration

Although we recommend using an already-established payment gateway, sometimes already-established programs just don’t tick all the right boxes. In the event that you haven’t found a suitable payment solution, you can consider the option to develop your own, as Savvy.io, one of our recent customers, did. For Savvy.io, we developed a cryptocurrency wallet for supporting, receiving, keeping and exchanging cryptocurrency.

Creating a custom payment gateway

This client came to us with a query on developing a payment gateway extension based on Savvy API. He had the following requirements for the extension:

  • It had to be capable of being integrated with the most popular e-commerce platforms (Magento, Magento 2, PrestaShop, OpenCart and WooCommerce).
  • It had to provide customers with the opportunity to safely pay for online purchases with the Savvy wallet.
  • It had to provide merchants with a reliable payment gateway able to accept and process payments following the best crypto-processing practices.

The first thing we did was a thorough analysis of every above-mentioned e-commerce platform. After learning all their features and peculiarities, we were able to create the best approach to develop modules for each. As a result, we developed a secure and reliable solution that successfully scales along with further Savvy API development. You can learn more details about the Savvy.io development process by reading the case study.

Final Thoughts

Your choice of payment gateway and how that gateway and its options are presented on your store will have a significant influence on the user experience of your customers. Choose well, and you’ll have more customers. Choose poorly, and you can easily guess the consequences.

We hope you now have a clear impression of the procedure of payment gateway integration for e-commerce step-by-step. However, if you still have questions about anything, or would like to discuss your project with an industry professional, don’t hesitate to drop us a line – we are here to help!
