Benefits of Using a Payment Gateway How Payment Gateways Work Types of Payment Gateways With Examples Choosing a WordPress Payment Gateway My Payment Gateway Recommendation FAQs Related to What Is a Payment Gateway? What Is a Payment Gateway? In eCommerce, there are several fundamentally important aspects of the online store. One of the most important is accepting payment from customers for the goods or services you offer. The system through which the payment is processed is often called a payment gateway. But what is a payment gateway? This label describes the system that handles the transfer of money from the customer to the store owner. In other words, a payment gateway acts as the crucial bridge between your online store and your customer’s bank or credit card. Think of it as the online equivalent of a point-of-sale terminal in a physical store. Its primary function is to securely transmit transaction information between the customer, your store, and the payment processor. Without a payment gateway, you simply can’t accept credit card payments or other types of online payments, making it a fundamental component of any successful EDD setup. Benefits of Using a Payment Gateway Aside from handling the transaction processing, a payment gateway has several other important functions. Streamlined Payment Processing Payment gateways automate payment collection and reconciliation. They make the handling of payments simpler and easier to set up. Before services like Stripe, PayPal, and Authorize.net were available, setting up a merchant account to process credit and debit card payments was a difficult, long, and labor-intensive process. Now it’s as simple as registering an account and connecting it to your eCommerce website with a few simple settings. Increased Sales Offering multiple payment options increases conversion rates. Payment gateways like Stripe make it easier to offer various popular payment methods on your eCommerce site. You can reach a wider audience and drive more conversions than you’d otherwise be able to. Payment gateways improve the customer experience. A smooth and secure checkout process enhances customer satisfaction. Enhanced Security Payment gateways protect your business and your customers from fraud. They are designed to keep customers’ information confidential and secure. In the best payment gateways, the customer’s payment information (credit card number and details, for example) never touches the website’s server nor is the information made available to the eCommerce store’s owner. The information is kept safe, secure, and confidential. How Payment Gateways Work Understanding the mechanics of a payment gateway can seem daunting, but it’s a straightforward process. In simple terms, a payment gateway system works behind the scenes to accept the payment from a customer and then facilitate the transfer of funds to the store owner’s bank account. The typical process looks like the following. Customer Checkout: The customer adds a digital product to their cart on your online store and proceeds to checkout. Payment Information: They enter their payment details (credit card number, expiration date, etc.) on your checkout page. Secure Transmission: Your eCommerce plugin securely transmits this sensitive information to the payment gateway. This is where the gateway’s security features (like encryption) become vital. Authorization Request: The payment gateway sends an authorization request to the customer’s bank or card issuer through the payment processor. Approval/Decline: The bank verifies the customer’s funds and approves or declines the transaction. Transaction Response: The payment gateway relays the response back to your store. Order Confirmation: If approved, your store processes the order, delivers the digital product to the customer, and notifies you of the successful sale. Funds Settlement: The payment processor transfers the funds from the customer’s bank account to your merchant account. Types of Payment Gateways With Examples While the core function remains the same, payment gateways come in different flavors. Below are the most common types of payment gateways you might encounter when setting up your online store. Hosted payment gateways redirect customers away from your site to the payment gateway’s secure server to complete the transaction. This simplifies PCI DSS compliance for you, as the sensitive data is handled entirely by the gateway. PayPal Standard is a classic example. Integrated payment gateways allow customers to complete the entire checkout process on your eCommerce site without being redirected. This provides a more seamless and branded experience. Stripe and Authorize.net are popular examples. Redirect payment gateways, similar to hosted gateways, redirect customers to a third-party page. But they’re often for specific payment methods like Alipay or Sofort. Choosing a WordPress Payment Gateway Nearly every online store requires a payment gateway to process payments. But not every business has the same requirements or factors to consider. Choosing an online payment gateway can be one of the most important decisions you make when setting up your store, so it is important to consider the payment gateway options carefully. Below are some key aspects to consider when researching, comparing, and choosing a WordPress payment gateway. Your eCommerce Solution If you’re using WordPress to create an online store, the two most popular eCommerce plugins to use are WooCommerce (physical products) and Easy Digital Downloads (digital products).
