Today we can pay for practically anything online in one click. However, this simplicity requires an excellent infrastructure. The order page is an essential element of any online business. The companies can significantly increase the conversion coefficient and offer their clients convenient payment methods. A reliable payment gateway helps merchants to develop their businesses and focus on their primary activity instead of processing the payments. Let’s look in detail at what payment gateways are and what benefits this integration can bring to merchants and various platforms.

What is a payment gateway?

A payment gateway is a critical element in the payment processing system, regardless of whether it is an online or in-store purchase. It is an external transaction mechanism that collects, transfers, and authorizes clients’ information in real-time to the merchant’s bank, which processes the transaction. Payment gateways are not all the same. You will need to understand and accept particular limitations each gateway provider has since the instruments’ infrastructure differ. A payment gateway is designed for:
  • Regulation of non-cash online payments between buyers and sellers;
  • Payment details verification for all parties involved;
  • Reducing fraud activity possibility;
  • Providing personal data security.
These are services that authorize credit card payments for online and offline businesses. These are equivalents for physical POS terminals in stores or restaurants. It allows customers to provide data about their credit card, and then the merchant securely receives it and transfers it to the bank.  It tells you if the cardholder's bank has approved the charge and sends your bills for settlement. Indeed, the term ‘’payment gateway’’ and many related terms from the debit and credit cards payment sector may not be defined in any legal, regulatory, or official documents, depending on your location. Hence, different people and organizations use these terms with different definitions.

Payment gateways as an essential element of e-commerce

A payment gateway conducts the whole e-commerce show and functions as an intermediary facilitating online transactions. Often these are money flows from those who pay for products and services to people who provide them on their websites. The digital intermediary helps online customers to pay for what they need in a blink of an eye.

Checking the information provided by payment recipients analyzes whether to approve such a transaction online. Thus, it also significantly reduces the risk of fraud, ensuring safe and secure cashless transactions between participants involved in e-commerce interactions.

The role of a payment gateway for merchants and platforms

Payment gateway services are necessary for processing all credit cards on the internet. This is the same process that the Point of Service (POS) device performs when you pay for your meal in a restaurant. They also process your retail purchases. Hence, a payment gateway's primary function is authorizing transactions between you and your clients. Furthermore, it protects clients’ credit card data by encrypting personal information and helps save it from fraud.

It is critical since many users are only sometimes confident in such operations within the virtual world. Thus, the company will be more attractive if the provider guarantees protection and reliability. As mentioned earlier, this instrument identifies the cardholder and provides a safe transaction from their account to the merchant's account or e-commerce platform. The payment gateway offers this entire flow. It maintains security by following a defined protocol and encrypting clients’ data.

Setting the appropriate payment gateway

If you work in the e-commerce industry, you will need a merchant account and a payment gateway to accept online credit cards. First, you must legally set up your business and choose a provider. You must create an account, buy a domain name, and have a running website. At that point, you should select a third-party processor to start accepting payments online. This system is usually a third-party processor that handles payment transactions. The processor also provides credit card machines to confirm credit card payments offline.

Selecting the provider for your business can determine the success of your business. The merchants must know why they require such an instrument and what services the gateway provider offers. For example, what features they will provide for companies, credit card machines, and other things they offer before including them as one. They need to be aware of service changes. Understanding the complete payment processing cycle for an online store will be critical to the long-term success of your online business.

How does the technology function?

Business owners don’t have to study the technical basics of gateway functionality, which is excellent news. Thus, integrations with e-commerce websites or any other website type require selecting a supplier. Next, it requires integrating it into your software with the help of a straightforward adjustment master. That’s it. Also, it is a benefit to know the payment gateway work scheme.

Payment gateways typically function according to the following standards:

  • The client makes an order on your website. They go to the card and enter the payment information.
  • The payment gateway receives the information, encrypts it, and passes it to the payment system through a secure channel.
  • The client is redirected to the payment system.
  • The payment processor verifies whether the transaction is successful and sends the client and the owner an appropriate message.
  • The customer can go back to the shop.
Thus, the payment gateway is responsible for interacting with the client and the payment processor. This connection must be efficient, fast, and, more importantly, secure since the payment system deals with the client’s personal information.

Requirements for integration with a payment gateway

It is critical to remember the legal aspect of the system integration process if you plan to use this instrument on your website and provide payment services. You must ensure that your clients can trust your website.
  • PCI DSS certification. Payment Card Industry Data Security Standard (PCI DSS) is a set of requirements businesses must meet to store, process, or transfer clients’ payment data. The primary target of the PCI DSS standard is to provide secure network infrastructure and cardholder data protection. Following this standard is essential in any region.
  • General Data Protection Requirements (GDPR) are a must for any organization that processes and stores personal information in the European Union. Hence, if your business functions in the EU or beyond the EU yet process the personal data of EU residents, then meeting GDPR requirements is obligatory. You can get more details on GDPR in the article on the GDPR compliance checklist.
  • Strict Client Authentication. SCA is a requirement of the EU Directive about payment services. It concerns all payment gateway providers who work in the European economic sector. SCA provides security for all e-payments via multifactor authentication.

How to add a payment method to the website?

Payment gateway integration is simple, yet it is crucial to understand several steps. Do it independently or ask our development team for help. Here are the steps to adding a payment method to the website.

1. Study the services of your hosting provider

Your website will need to use web hosting services for quality maintenance; the hosting provider offers all functions that you might require. The hosting provider might provide basic functionality and paid support. Some hosting providers give payment integration services that you might be interested in.

2. Select a payment gateway provider

You can select a payment gateway provider according to the requirements of your website. Remember that platforms without hosting are more expensive since clients do not need to leave the website to process payments. Please, ensure that the providers are reliable.

3. Ensure that your website meets the local regulations

Payment integration through a website is a complex process that can’t be completed without following the legal requirements. Meeting PCI DSS is the first step you must make in offering payment services to your clients. Please, keep in mind the personal data processing regulations in your region. If you ignore it, your business will be charged with sanction fees, and what is more important, you will lose your clients' trust.

4. Add payment methods that you want to employ

Payment methods may depend on the type and features of your business. Payment methods include credit and debit cards, mobile payments, bank transfers, e-wallets, etc. If you select a particular method, use the Sandbox account (a protected account for the secure launch of any application) to verify how the payment gateway functions and whether all function work right.

5. Register a merchant account

When you are ready with the payment gateway setting, you will need to create a merchant account and connect the payment system for the website with your account. Organizing the payment transfer from clients to your bank account (company account) is necessary.

Conclusions
