E-commerce is now the driving force of economic activity. As more businesses move their operations online, having a robust payment gateway is critical to success.

However, simply installing a payment gateway is not enough. To really excel in the world of e-commerce, you need to use your merchant panel effectively to leverage the full potential of your payment gateway.

In this article, we dive into the world of payment gateways, explore their inner workings, discuss third-party payment integrations, and also touch on the possibility of building custom gateways for your own needs.

What is a payment gateway?

A payment gateway is a technology that allows online businesses to securely process electronic transactions and enable customers to complete purchases and online payments over the Internet.

It acts as an intermediary between the buyer’s payment source (such as a credit card) and the seller’s bank account, ensuring secure funds transfer.

Main features of payment gateway:

  • data encryption: Payment gateways use encryption protocols to protect sensitive customer information during transmission and reduce the risk of data breaches.
  • Real-time processing: Payment gateways process transactions instantly, provide instant feedback to customers, and provide efficient order processing for merchants.
  • Website integration: The payment gateway integrates smoothly with the merchant’s website and provides a seamless shopping experience to the customers.
  • Payment method support: A good payment gateway supports multiple payment methods and caters to a wide range of customer preferences.

How payment processing works

Payment processing through a payment gateway involves the following series of steps:

  1. Customer initiates payment: The process begins when a buyer selects a product or service on a seller’s website and goes to the checkout page. This initial decision begins the transaction process.
  2. Secure data transmission: Once the customer is ready to pay, the payment gateway will work. Payment gateways encrypt customer payment information (usually including credit card details), ensuring the confidentiality and security of this sensitive data.
  3. Transaction approval: Encrypted payment data is sent from the payment gateway to the payment processor. This processor acts as an intermediary and forwards payment information to an associated financial institution, such as the merchant’s bank.
  4. Authorization response: When a financial institution receives a payment request, it immediately considers it for approval. They evaluate factors such as availability of funds, legitimacy of transactions, and carry out various security checks. This authorization response is sent back to the merchant via the payment processor and payment gateway.
  5. Transaction completion: Once the transaction is approved, the payment will be successfully transferred from the buyer’s account to the seller’s account. Additionally, the customer will receive a confirmation message confirming that the payment process has been completed and the selected product or service has been successfully purchased.

Benefits of third-party payment integration

While payment gateways provide the core functionality for processing payments, you can extend the functionality of your payment processing system by integrating third-party payment providers.

Benefits of third-party payment integration

Third-party payment providers offer professional services, alternative payment methods, and international payment options that extend the reach of your e-commerce and improve customer satisfaction.

Here’s a detailed overview of the benefits you get with this integration:

  • Variety of payment options: Third-party providers offer a wide range of payment methods, such as digital wallets (PayPal, Apple Pay, etc.), cryptocurrencies, local payment systems, etc., and customers can choose their preferred option.
  • Global expansion: Integrate with international payment providers to reach new markets and accept payments from customers around the world.
  • Reduced friction: Offering multiple payment methods minimizes checkout effort, leading to higher conversion rates and customer satisfaction.

How do I build a custom gateway?

Building a custom payment gateway is a difficult task that requires a thorough understanding of payment processing, security protocols, and compliance with industry standards.
