  • Ensuring strong safety, and 
  • Appreciably increasing revenue

What is Payment Gateway Integration

Integration of a reliable payment gateway seamlessly connects an e-commerce site or mobile application to a payment gateway – a digital bridge facilitating secure transactions between customers and merchants. 

This gateway is a third-party service that authorizes and processes transactions in real time, supporting numerous payment methods with credit scorecards, debit cards, e-wallets, and bank transfers. This integration is essential for corporations wishing to streamline their online transactions, offering a frictionless fee for customers.

You may ask, why integrate a third-party service on your website and not develop a payment gateway software instead? Let us explain. 

A readymade payment gateway software is apt for small businesses that don’t require too many specifics. In the USA, 99.7% of businesses are small businesses, of which 80% are run by the owner, while 16% or so have less than 20 employees. 

Such small businesses do not require custom-made software to deal with their customer transactions. A reliable third-party payment gateway can do the job alright. 

However, large enterprises with diverse requirements and preferences need robust, customized software tailored to their complex payment processes. However, such businesses already have custom-made payment software, dealing with their day-to-day transactions. It is the small and medium-sized businesses that need to go through with payment gateway integration on their websites. 

The Necessity of Payment Gateway Integration Today

The significance of payment gateways transcends basic transaction processing today. In an era dominated by e-commerce, understanding payment gateway integration requirements is crucial for conducting secure, efficient, and versatile online transactions, which is paramount for online businesses. Not only does it simplify the buying process, but it also broadens the customer base, enabling businesses to operate on a global scale. Moreover, it instills a sense of trust and security in customers, knowing that their financial data is handled securely, which is indispensable for building long-term customer relationships.

So how does an integrated third-party payment gateway ensure secure transactions? 

Well, all payment gateways need to incorporate various security technologies,e.g. tokenization, fraud management, and of course, encryption, to enable 100% secure financial data management and transactions. On top of that, these gateways need to comply with the PCI DSS (Payment Card Industry Data Security Standard), and SSL/TLS Encryption standards, among others to maintain their reliability in the market. They also need to be open to recertifications and audits as and when required. 

With such a reliable payment gateway integrated into your website, there will be a seamless and secure flow of financial data across both parties (the customer and the merchant), reducing the chances of cart abandonment, fraud, and data theft. 

Considering the Inherent Benefits of Payment Gateway Integration

While it may not be easy to choose a particular payment gateway from the list of available options, you need to understand the “Why” first. Every business has different transaction needs, thus different payment gateways to consider. However, the benefits that you can get from various white-label (existing) payment gateways are somehow similar. Let us give you an idea regarding that. 

A drastic increase in sales

Integrating a payment gateway directly influences the sales volume by offering a seamless and flexible checkout process. Businesses effectively widen their market reach by enabling customers to purchase from anywhere in the world, at any time, with their preferred payment method. This adaptability to global trends and preferences can significantly elevate sales figures, tapping into markets previously beyond reach due to payment barriers.

Improved Customer Experience

A paramount factor determining the success of online purchases is the ease and speed of the checkout process. Payment gateway integration ensures a smooth transactional flow, keeping customers within the business’s ecosystem rather than redirecting them to external payment sites, often leading to cart abandonment. Moreover, it provides:

  • Instant feedback on the transaction’s success or failure.
  • Enabling quick resolution of payment issues.
  • Thus enhancing the overall customer experience.

Security Assurance 

The bedrock of successful online transactions is robust security. Payment gateways are designed with advanced encryption protocols and security measures to safeguard sensitive customer information against potential fraud and breaches. Adhering to international security standards such as PCI DSS, PSD2, SSL/TLS Encryption, etc. ensures that businesses are protecting their customers and maintaining regulatory compliance. This is essential in the digital age, where data breaches can significantly tarnish a company’s reputation.

Expanding Globally

If you look forward to expanding your business globally, adding a payment gateway to your website can be the first step. Several white-label payment gateways support multiple currencies, giving you the scope to reach out to a global base of customers. Nothing can be better than paying for international services/products with local currencies, right? By offering this experience to your global clientele, you can increase your chances of global business expansion. 

How to Choose The Right Payment Gateway Provider 

Before integrating a payment gateway, you should first choose one. According to the 2024 list by Forbes, the following are the best white-label payment gateways you can consider for your website:

  • – Fraud prevention at its best
  • Stax – Hefty transactions faster
  • Shopify – eCommerce startup owner? This is yours to get! 
  • Payline Data – For all those subscription-based transactions
  • Elavon – For POS systems 
  • Helcim – High volume payments faster 
  • Stripe – Tailored payment systems 
  • Clover – Best for small businesses in the food industry (clubs, restaurants, diners)
  • Square – The retailers’ favorite
  • PayPal – Highly versatile diverse payments for global businesses

You should consider some other factors while choosing the right payment gateway for your site. These are:

Payment processing and subscription fees 

What does your business need? Should you go for a diverse payment gateway that offers multiple facilitates for easy transactions? Or should you opt for a simpler, cost-effective one? The two ways you have to pay for any payment getaway are subscription fees – money that you have to pay every month, and payment processing fees – the money that you need to pay for processing each transaction. 

See if the payment gateway offers free trials to help you evaluate its services for a short period. You also need to consider if the payment will happen on your website or off-site. For example, Stripe and Square deal in off-site transactions, while PayPal mostly handles transactions that are redirected to their site. If you want to integrate a payment gateway that will allow all transactions to happen on your servers, find one accordingly. 

Security Features

Given the critical importance of data security in online transactions, evaluating a provider’s security measures is paramount. Look for advanced security technologies like SSL encryption, tokenization, and fraud detection capabilities. Ensuring compliance with PCI DSS and other regulatory standards is crucial for maintaining data integrity and customer trust.

Accepted Payment Modes

This flexibility is essential for businesses expanding their market reach internationally, where payment preferences vary widely.

Volume of Transactions 

This is yet another factor that many business owners tend to overlook while opting for a reliable payment gateway. You should check if the chosen payment system can handle the scale of your business. To ensure that, you need to estimate the volume of transactions in your business processes. Most payment getaways charge a high sum for exceptional transaction volumes, so it is better to get an idea first. 

Last but not least, you should check if the payment system can handle an increased volume of transactions when your business scales up. It should cater to horizontal scaling if your business requires the addition of extra resources or instances to distribute the load. 

Mobile-friendliness and overall customer experience 

According to a report by Grand View Research, the value of the mobile payment industry will grow at a CAGR of 36.2% between 2023 and 2030.

Hence, it is imperative for the payment gateway that you have chosen for your website to be mobile-friendly. Besides, you also need to confirm if the gateway offers a seamless overall user experience on all devices.

  • Payments Services Directive 2 (PSD2)
  • ISO 27001 – International Standards for IT management systems 
  • GDPR (General Data Protection Regulation)

Type of Integration

Not all payment gateways offer easy integration. Before you finalize one, review the system’s API documentation to evaluate how hassle-free the integration will be.

Also, do not forget to evaluate the provider’s developmental support, in case of issues or hassles while integrating the payment gateway into your website. 

Customer Support

Transaction issues must be resolved quickly to maintain customer satisfaction and protect revenue. Go only for providers offering 24/7 support via multiple channels to ensure accessible and effective troubleshooting.

Step 2: Setting up an Account

With a provider selected, the next phase is establishing a merchant account, which will be the repository for the funds acquired from online transactions. The setup process includes submitting detailed business information and conducting due diligence to verify the business’s legitimacy and credit risk.

Step 3: Acquiring the API Credentials

Sandbox testing is examining any software in an isolated environment without affecting the parent application. You can perform this test without real transactions. 

Step 6: User Acceptance Testing (UAT)

Ask them to give honest feedback on their experience of making transactions through the new payment gateway. Note down any issues that they have faced and ask your developers to conduct API calls to the provider for changes or modifications if required.

If there is anything, like the introduction of a new security feature or a new update on the vendor’s side, update the system on your website immediately. 

Final Thoughts
