What is an Internet Payment Gateway?

An internet payment gateway is a technology that enables online merchants to securely process and accept electronic payments from their customers. It acts as a middleman between the merchant’s website and the financial institutions that issue credit and debit cards, as well as other payment methods like e-wallets and bank transfers.

Internet payment gateways are essential for online businesses, as they provide a convenient and secure way for customers to make payments without having to worry about fraud or identity theft. 

They also allow merchants to expand their customer base by accepting payments from customers all over the world, regardless of their location or preferred payment method. However, not every internet payment gateway can accept international payments, so keep an eye out for this.

How Does an Internet Payment Gateway Work?

While it is important to understand that an internet payment gateway acts as a middleman between the customer’s bank and the business’s bank, there is more to the process than the money just moving from point A to point B.

An internet payment gateway works like this:

  1. The customer decides which product or service they want to purchase from the business’s website or app and puts the item in their online cart.
  2. The business website or app sends the payment information, including the customer’s credit card number, expiration date, and security code, to the internet payment gateway.
  3. When the internet payment gateway gets the customer’s information, it encrypts the payment data and sends it to the acquiring (business’s) bank, which is responsible for processing the payment.
  4. Next, the acquiring bank sends the transaction information to the customer’s issuing bank to confirm that the customer has sufficient funds to complete the transaction.
  5. When the request is received, the issuing bank either approves or declines the transaction based on the customer’s available funds and any other fraud protection measures.
  6. Next, the issuing bank sends a response back to the acquiring bank, which is then sent back to the payment gateway.
  7. When the payment gateway receives the response, it sends it back to the business, letting them know if the transaction was approved or declined.
  8. Finally, If the transaction is approved, the business completes the transaction and the funds are transferred from the customer’s bank account to the business’s account.

Throughout the entire process, the internet payment gateway uses encryption and other security measures to protect the customer’s payment information and prevent fraud. By using an internet payment gateway, businesses can offer their customers a convenient and secure way to pay for their products and services online.

Different Types of Internet Payment Gateways

There are several types of internet payment gateways available, each with its own unique features and benefits. This means the business needs to do research with their needs in mind to determine which type of payment gateway is best.

Hosted Payment Gateway

With hosted payment gateways, the customer is redirected to a third-party website to complete the payment process. The payment gateway is hosted by a third-party service provider, who handles the payment processing and security.

Self-Hosted Payment Gateway

Self-hosted payment gateways allow the customer to stay on the business’s website throughout the payment process. The payment gateway is integrated into the business’s website, giving them more control over the checkout process.

API Payment Gateway

API payment gateways provide a more customizable payment processing solution, allowing developers to integrate payment processing into their own applications and websites.

Mobile Payment Gateway

Mobile payment gateways allow customers to make payments using their smartphones or other mobile devices. These gateways can be integrated into mobile apps, mobile websites, or other mobile-based payment systems.

Features to Look For in an Internet Payment Gateway

When selecting an internet payment gateway, there are several important features to consider.
