Payment gateway integration in websites had long become a necessity rather than a handy yet surplus addition back when credit cards were less prevalent. Customer safety and convenience are currently the number one priorities, which means you should opt for adding an easy, hassle-free, and secure payment system to your online business as soon as possible.
Modern payment solutions have to tackle many issues – from minimizing cart abandonment to being helpful and less invasive by carefully guiding the customer to the desired outcome. First and foremost, it comes down to choosing both the right type of gateway and a suitable provider to create that happy medium of what you want and what your customer needs. Second, the integration process itself.
Our team at DICEUS is here to guide you through all these points to ensure you make a successful payment integration that is also a right fit for all your business requirements.

Simply put, a payment gateway is an online service that warrants the money exchange between a retailer and a customer in both brick-and-mortar stores and e-commerce. Being such a basic need in every online purchase, it is a staple in building any new e-store. A correct payment gateway transaction should have relevant encryption and security protocols to protect the data coming from customers to merchants.
There are several benefits from using a payment gateway on your e-store, apart from security. Firstly, it helps online stores get more sales that are not local and expand their customer base. Online payment for business also saves time by speeding up transactions that a bank would manually process, plus payments can take place at any time of day or night regardless of the bank’s work hours.
As the name suggests, a payment gateway is an opening (a gate) for a subsequent payment journey. Here’s the structure of the core transaction flow:
When accepting payment on a website, there are a few types of credit card transactions processing you might encounter. Here are the main ones:

E-commerce businesses have to be extremely diligent in protecting their customers’ personal data. Besides the standard two-factor authentication method, they can also do that by using the following solutions:
There are two payment gateways available today – hosted and non-hosted (or integrated). The former is the ready-made solution offered by online payment gateway providers, whereas the latter has to go through an integration process.
The hosted gateway sends the customer from the checkout page to another web processing platform to finish the payment and then back to your page after it’s complete. If choosing a hosted solution, make sure to go through a well-known service to minimize the unfamiliar feel.
From a merchant’s standpoint, it is a pretty simple process – the solution is cheaper and requires less time to get it set up and running. However, using third-party services and their resources also means not adhering to security protocols as the providers have it covered.
The additional steps and jumps can be slow and potentially annoy the customer, especially if the service provider is unfamiliar. Another con is that some providers allegedly keep your customer’s data after discontinuing the contract.
This solution means integrating payment API for the website and having it stay on your checkout page by connecting you directly to the gateway. As a seller, you are responsible for providing a smooth, safe, protocol-compliant payment process. The integration process is also a bit more complex and, even with ready-made tutorials, still requires some knowledge about web development.
The retailer has complete control over all payment transactions. The personal data of all the customers is never handed over to the third party, which is great for medium to large businesses with an extended client base. The store can also customize the complete checkout process and make it more user and mobile-friendly.
In this case, stores have to follow all the strict security rules themselves without additional help, which adds to the overall cost. And finally, the store website’s architecture has to be able to uphold the provider’s features.
Selecting a simple payment gateway comes down to a few key factors depending on your business type, your customers, and other internal and external factors.
Cost depends on your total turnover since all services request a fee for using their tools. The most popular types of payments are per transaction, per month, and for gateway installation or account setup. Some charge additionally for refunds and chargebacks. The fee percentage may range from 2% to 4%. Take a look at some of the pricing plans – PayPal, Stripe, or Authorize.net.
Check for a maximum and minimum transactions amount that a provider can handle and decide according to your business size and price of items. For example, if a company is not selling houses or something equally substantial and expensive, an average maximum capacity is enough.
Even though credit cards still hold the title as the most popular payment method, PayPal, Union Pay, mobile payments, such as Google Pay, Samsung Pay, and Apple Pay, are so widespread that it’s not wise to discard them. The same goes for international currencies support.
Take a look at the four popular providers’ features and fees comparison.
After you’ve chosen your provider and a suitable gateway type, the next step in your journey to add a payment method in the website is signing up for a merchant account. The rest depends on the chosen method.
Our team at DICEUS also provides integration services, combined with consulting, audit, maintenance, and custom development. Now let’s take a look at some of the steps more directly.
The previously mentioned PCI DSS is the key ingredient to making your payment process as safe as possible. To comply with this standard, you must first determine your compliance level out of four available, based on the number of transactions your business has previously handled.
Then after poring over this Self-Assessment Questionnaire, you have to complete an exam that has nine different versions depending on your business type. Next goes the External Vulnerability Scan by the Approved Scanning Vendor, after which you present your documents to the bank.
Hosted gateway method prompts the merchant to connect their e-store straight to the gateway and obtain an SSL certificate while also getting the gateway’s credentials, including the merchant’s ID, MWS access key, and a secret key.
Usually, you can get detailed guidelines on integrating a hosted solution on each provider’s website. For example, here are the overviews of the few providers’ methods.
To integrate PayPal, you need to add and customize a Smart Payment Button. Suppose you need to sell a single product or service at a fixed price – head here. For multiple items, it’s better to assemble PayPal Checkout – this doc for developers can guide you.
Before adding the Button, check if you have a business account. Then, in the “Tools” section, you can create a new button, as shown in the picture. After following the instructions that ensue, you’ll get an HTML code you can use anywhere on the website.
Stripe is both PCI-compliant and supports all main credit card options. Follow this link to find full Stripe checkout documentation that will help you create a secure payment page or this link for Web Elements. And here you can explore how the Checkout looks and feels for either one-time payments or recurring ones.
Another excellent option is Amazon Pay – it blends organically into your website and, unlike other hosted options, doesn’t redirect a customer completely away from your store. First, you need to create a business account, then a buyer account to test the integration in a Sandbox environment. You should be all set after getting the certificate and credentials we mentioned earlier.
To integrate credit card payment in the website in a non-hosted way, you need to connect the gateway to your server through an API. Here’s a brief outline of the Authorize.net and Opayo (SagePay Direct) integration methods.
One of the oldest payment gateway providers, Authorize.net can also be integrated by getting access to its API through a sandbox account with merchant authentication. You can create the account here. Another option is to look for modules and extensions available on the Internet.
With Opayo Server integration, the e-store has no need to collect payment data – the gateway provider takes care of everything. Check here for the API Reference section and here for the companion guide for shared API.
A larger business might be interested in a custom payment gateway. Even though the cost of development can go from $150,000 up to $500,000 or more, the benefits of customization and not depending on fees can be quite appealing. Less costly might be turning to an open-source solution, for example, OmniPay.
