Table of Contents
Are you interested in developing a secure payment gateway? If yes, this article will answer your questions.
Every business relies on the customer’s payment. For this reason, it’s crucial to have a payment gateway that is as comfortable as possible. Many people no longer use cash for payments. It’s clunky and uncomfortable to count every penny. We’ve all been in situations when a sales assistant makes mistakes with it. Let’s not forget the Internet, too: cash is impossible to use there. That’s why society needs online secure payment. In this article, we review payment gateways and study how to integrate them safely. This framework is crucial because payment gateway security prevents privacy problems.

What Is a Payment Gateway?
Payment gateway is a technology for electronic payments (credit or debit cards). It allows businesses to accept electronic payments from customers. The idea behind such a system is simple: it bridges the merchant website and the payment processor. A payment gateway is a ‘middleman’ simplifying the transfer by automating most processes concerning credit card information. Why is it so important? A secure payment gateway, for example, allows the customer to put their credit card into a scanner and pay without cash.
How Do Payment Gateways Function?
Payment gateways don’t require anything complex to function. Let’s look at the whole process from the standpoint of a customer, Jack, who buys a product online. He wants to buy RAM for his computer from some web store. After selecting the ware with a consultant, Jack goes to the checkout page. The individual reviews his purchase list and approves it after seeing the price. Then, Jack puts his credit card data into the special form provided by the website, which acts as a secure payment gateway. The software checks the information on the card. If it’s correct, the payment gateway sends the data to the bank, asking for the transaction. In most cases, no problems occur, and the payment processor receives positive feedback, informing the customer and the vendor about the successful transaction.
The Purpose of a Payment Gateway for Businesses
Comfort is one of the main reasons businesses integrate a payment gateway. Without such software, processing any credit card payments fast would have been impossible. If we recall Jack from the preceding section, he would have had to wait a lot for transaction approval. A secure payment gateway removes the need to contact banks directly, saving time for everyone.
Some other reasons for using payment gateways exist too. Firstly, they prevent errors, which may be inevitable with direct payment. Even an in-depth Internet search shows that almost no errors appear in payment gateway systems. Secondly, such systems prevent fraud by having access to banking databases. An average secure payment gateway can review addresses and card codes. This means the technology in question saves a lot of time for the average user.
Secure Payment Gateway Integration Methods
Multiple ways exist to create a secure payment gateway. Here are some of the most widespread approaches. We’ll review them all from the standpoint of Jack. Let’s imagine he wants to buy a processor this time from some hardware store:
A. Redirecting to the payment website
In this case, the whole process is basic. Jack selects the product and goes to the checkout. After he reviews the ware list, the vendor redirects him to the secure online payment gateway. There, he can enter all the key data and perform the payment. We’ve already discussed how the whole process goes. The idea here is that the vendor doesn’t integrate any payment processing elements into the site, outsourcing it to the outside service instead.
B. Integrating the payment form
The user experience mentioned above can seem quite scary for some individuals. This means most sites work with payment gateway integrations in different ways. Regarding payment form integration, Jack doesn’t have to visit other websites. Instead, he needs to fill out a form on the store website. It collects all the data relevant to the payment gateway, processes it, and sends the information to the payment software. This method is beneficial because it integrates the payment process into the store design.
C. Integrating a site within site via the IFRAME
Some sites also integrate a secure payment gateway directly into their design. From the standpoint of Jack, it looks this way: he goes to the payment page for his processor, and the gateway appears to be integrated into the site. Instead of going to it via redirection, Jack can fill in the data on the other site within the vendor’s store. This means that a site appears within a site in this case. For this goal, we need an IFRAME. This technology allows putting one webpage into the other, displaying them simultaneously.
D. Using a payment gateway API
Lastly, it’s possible to integrate a payment gateway directly into the website. For this, we need an API, a set of instructions that allow configuring the relevant software. Regarding Jack’s user experience, the process is similar to IFRAME integration. Integrating the secure payment gateway interface into the website is also possible. The difference is that the site owners have full control over the data. Such an arrangement is perfect for collecting high-quality statistics.
How to Make the Payment Gateway Secure?
There are multiple ways to guarantee the long-term security of a payment gateway:
SSL, or Secure Socket Layer, is an encryption framework used everywhere. The idea behind it is simple. During the first website visit, the server (a computer on the vendor’s or payment gateway side) establishes an encryption code with the client’s browser. Then, a series of third-party certificates (special encryption codes) ensure that the same person uses the established authentication code during the website visit. This approach is vital for online secure payment because it prevents identity theft.
Adhering to the PCI standards
The modern banking industry has clear standards for the processing of financial data. For example, all credit cards have to feature multiple layers of protection, such as CVC and access codes. The key idea here is to choose the payment gateway adhering to all the standards. Services such as Mastercard or Visa don’t work with companies that fail at integration. If you have some worries, ask your potential partner company if the secure payment gateway is standard-oriented.
We all do repeated transactions on some sites. The worst practice, in this case, is storing the credit card data in plain text files. If someone breaks into your servers, that’s a perfect invitation to massive data theft. Tokenization prevents this problem. It encrypts the credit card data and creates a special sign, or token, which the clients can later reuse for other purchases. If someone breaks into the payment gateway servers, all they’ll find is the encrypted (and unbreakable) user data.
Using Phones for 3D Security Authentication
Most credit cards have a connection to users’ phones. This means they can take part in the security process. How does this work? After the user confirms their credit card data, they’re redirected to a website that asks them to enter a separate security code. The secure payment gateway sends this security code to their smartphone. Sometimes, new frameworks ask for fingerprints or facial recognition. The idea here is simple: even if someone steals credit card data, 3D security makes it impossible to buy anything without a telephone. After all, you need to enter a code first.

6 Steps for Online Secure Payment Gateway Integration
If you’re reading this article, you’re likely interested in establishing a secure payment gateway in your firm. Let’s look at the six steps that can help integrate a secure payment gateway:
Step 1. Analyze the current situation
Above all, we recommend you look at the situation in your business. What problems with security does it have? What lacunas need to be closed? The more information one collects, the easier it will be to transition to the next steps.
Step 2. Plan your project
Once you know your problems, it’s easy to understand what’s necessary for the site or business. In our case, the issue may lie in the absence of a secure payment gateway. Create a clear plan for solving this problem. It should have organizational steps and a definite selection of software and partners. Let’s look at the potential items to include in the plan below.
Step 3. Outline how the integration will work
The primary element of your plan is the analysis of the way the integration will work. What to include here? Choose the platform for the integration and how you’ll integrate the payment gateway. We recommend looking at several service providers to guarantee a high quality of choice.
Step 4. Selecting a good tech stack for the integration
Every integration requires some programming. This means you must write code with minimal vulnerabilities and maximal speed. What to do? We recommend Node.js because it’s a web-specific language taking many of its characteristics into consideration. The best idea is to consult programming specialists: they’ll offer you some high-quality options.
Step 5. Implement the online payment gateway and test it
Once you have chosen all the integration elements, it’s time to implement them. Ask your programming specialists to integrate the secure payment gateway into the relevant site. Once you have it, start testing every aspect of the software integration. The more information you have, the better. Imagine as many situations the users may encounter as possible.
Step 6 (optional). Support your system and let it evolve
Once you have developed the integration, it’s time to review the user feedback. For example, if someone doesn’t like the redirection option, a better choice is to use site integration. Try to make the payment gateway integrations as comfortable for the users as possible. The more potential issues experts review, the better.
How to Choose a Payment Gateway Provider
Many security aspects depend on your ability to choose a good payment gateway provider. Let’s see some steps capable of helping you choose a good one for payment gateway integrations:
Review the integration price
Most services have some price for the integration. You should look at different services before making a full-scale choice. Our recommendation here is simple: analyze as many providers as you can.
Analyze the transaction limits
Every website has its limits for transactions. Some stores provide low prices for the services. Others sell large-scale wares, requiring significant investments. Different payment services have diverging transaction limits. Before you integrate a payment gateway, learn as much about them as possible.
Learn what integration functions a merchant account offers
You may have some specific ways to integrate the payment provider into your site. Perhaps, you would like an API. If one isn’t attentive, the choice can be problematic as the payment provider won’t give access to necessary tools. You should always review the relevant partner’s capabilities before accepting them. Don’t hesitate to contact the providers directly and ask their support department for help regarding these questions.
Ensure that the gateway supports all the payment methods you want
A major factor in gateway support is the ability to work with various payment methods. Not all payment providers work with the frameworks that are of interest specifically to you. Once again, one should first contact potential partners and analyze their responses. Most services are rather upfront about their capabilities.
Think about payments via mobile phones
Many customers are buying everything via smartphones today. Integrating a payment gateway may require a focus on this aspect. Look at the capability of your provider in this regard too.
Review if the provider allows your product type
Different providers work with diverging product types. For instance, most online payment gateways focus on relatively small wares that cost less than 5000 dollars. They may include everyday wares such as dishwashing machines and personal computers. But what if you’re selling cars? Many payment gateways can refuse to work with you because of their price and special regulations assigned to them. In this light, the best option is to focus on specialized ware providers.
