That’s why payment gateway and payment gateway integration come in.

Being a top fintech technology, it enables businesses to accept payment digitally in a split second on their online platforms.

Want to achieve this in your platform?

Well, there’s a lot more to integration payment gateway than meets the eye.

So, let’s decode the sophisticated world of payment gateway integration, custom payment gateway development, challenges, and much more in this guide.

What is Payment Gateway Integration?

Let’s answer the big question first, what is payment gateway integration?

Starting with the basics, the term “payment gateway” refers to a front-end technology that allows businesses to accept payment from customers via digital wallets, debit cards, credit cards, or online banking methods.

Payment gateway applications range from physical stores receiving payment through physical cards to online stores which allow customers to pay via digital solutions.

Now, coming to “Payment gateway integration”, it is process of connecting your website or app to a payment gateway service. This allows customers to enter their payment information securely and process transactions electronically.

While this might seem like a new concept to some, it has been for a good while, being used in some of the top on-demand apps; plus any other app that handles payment processing.

Fintech Statistics show, Digital payments apps have become a dominant fintech product, claiming 25% of the market share.

As a consequence, payment gateway integration payment gateway integration in mobile app development has become a popular choice and feature.

Here are some of the most common app types that take advantage of payment gateway integration:

Popular Apps Using Payment Gateway

• Gig Apps
• Taxi booking apps
• Fintech apps
• EdTech Apps
• Dating Apps
• Cash Advance Apps

And so on.

All in all, payment gateway integration has become a popular tool not just in app development, but also in web development, as a lot of us have already seen.

Core Features of Payment Gateway Integration

There are 5 core functions of payment gateway integration. And they open the door to numerous digital payment features.

Now, let’s discuss each of them below:

1. Authorization

The first core function is authorization.

As the name suggests, it refers to the part where the payment gateway verifies the customer’s payment information.

Integrated payment gateways will communicate with the concerned bank. This is done to check if there are required funds for the transaction.

Based on the result, the gateway system will come back with an authorization response, giving “approved” or “declined”.

2. Capture

Following capture, the second function is capture. This ensures businesses receive funds for the authorized payment.

This functionality allows the platform to confirm the payment and approve funds transfer, taking place following successful order fulfillment or service delivery.

3. Sale

More often than not, authorization and sale happen simultaneously, and this event is known as a “sale”

In simple words, this means a more streamlined and faster fund collection process.

4. Refund

As the name suggests, the refund function of the integrated payment gateway system returns the funds to the customer’s account.

This is activated in case of order cancellations, product returns, or other scenarios requiring a refund.

5. Void

Lastly, we have the void function.

It enables the platform to cancel authorized transactions prior to capturing.

So, why is it important? Well, the void function becomes very useful in case of abandoned carts, incorrect orders, or other times when the transaction shouldn’t be finalized.

Now that we are done with the meaning of payment gateway integration, popular apps that use it, and its core functions, it’s time to look at the payment gateway integration methods.

Types of Payment Gateway

There are different types of payment gateway integration.

Each of them has a different in their nature of working, giving us unique advantages as well as drawbacks.

Let’s look at these different payment gateway integration methods, below:

Type 1: Hosted Payment Gateway

Let’s start with the first one, which is, a hosted payment gateway.

This is the most common and user-friendly choice for payment gateway integration. In this system, the customers will be redirected to a secure payment page hosted by the gateway provider.

Here, they will enter the information and once the transaction is finished, they are redirected to the original platform.

• Pros: Easy to set up and requires minimal technical expertise. Offers a secure checkout experience for customers.
• Cons: Limited customization options for the checkout page. Merchants have less control over the customer experience.

Type 2: API-Hosted Payment Gateway

Just like hosted gateways, customers enter their payment information on your platform.

However, the processing happens through an API provided by the gateway, offering more flexibility and customization.

This is one of the popular use cases of open banking APIs.

• Pros: Offers a seamless checkout experience without redirecting customers. Allows for greater control over the checkout page design and user experience.
• Cons: Requires more technical expertise for integration and maintenance. Merchants are responsible for PCI compliance and data security.

Type 3: Self-Hosted Payment Gateway

As the name suggests, self-hosted payment gateway integration doesn’t require customers to leave the platform.

Meaning, they can enter payment information directly onto the platform. The entire transaction is processed on your servers.

This offers the highest level of customization and control.

• Pros: Provides complete control over the checkout experience and branding.
• Cons: Requires significant technical expertise and resources to set up and maintain. Merchants bear full responsibility for PCI compliance and data security, which can be complex and expensive.

Tyep 4: Local Bank Integration Gateway

Lastly, we have the local bank integration gateway.

This option connects your website or app directly to local banks or payment networks in specific regions.

It allows customers to use familiar local payment methods.

• Pros: Enables acceptance of popular local payment methods, catering to specific regional preferences.
• Cons: Can be complex to set up and maintain, requiring integrations with multiple local providers. May not be suitable for businesses operating globally.

Now that we are done with different payment gateway integration types, you might be wondering, which one is the right for you.

Well, here’s how to find out.

How to Choose the Right Payment Gateway Integration Methods? Factors To Consider

 It goes without saying it’s important to choose the ideal payment gateway integration for your next project.

But how do you choose the right one?

Well, while there’s no guide to it, here are a few factors that you can consider while doing it.

• Technical expertise: Hosted and API-hosted options are generally easier to integrate for businesses with limited technical resources.
• Customization needs: If you require a highly customized checkout experience, API-hosted or self-hosted options might be preferable.
• Security considerations: Merchants must ensure PCI compliance and data security regardless of the chosen integration method.
• Target audience: Consider the preferred payment methods of your customers, especially if you cater to specific regions.

These are some basic factors to consider, you can always go one step ahead, and consult a payment gateway integration service provider for greater insights.

How Does Payment Gateway Work?

Let’s get a bit technical here, shall we?

It’s time to learn the workings of payment gateway.

A payment gateway acts as a secure intermediary between online stores, customers, and their financial institutions, facilitating smooth and secure online transactions.

Here’s a breakdown of how it works:

1. Customer initiates purchase

The payment processing flow starts with the customer deciding to buy something from the platform.

The core process remains the same whether we are talking about an eCommerce app or some NFT platform.

In any case, the user moves to the checkout page and enters their payment information, including card details or alternative payment method credentials.

2. Payment Information Collection

As soon as the customer enters their payment detail, the integrated payment gateway collects the info via encryption or tokenization.

This is done to keep the data secured when being processed through different channels.

3. Fraud check and authorization

Once the information is collected, the payment gateway will put it through a firewall that checks it for fraud.

If a green light is given, the payment information is sent to the merchant service provider i.e. the fintech company that handles payment processing for business.

4. Communication with the issuing bank

It’s important to establish secure communication with the bank and that’s what happens in this step.

Here, the acquirer forwards the information to the customer’s issuing bank (the bank that issued their credit or debit card).

In addition to this, the issuing bank verifies the customer’s account details and available funds and performs additional fraud checks.

5. Authorization decision

Now, with that said and done, it’s time for authorization. Based on the verification and fraud checks, the issuing bank either approves or declines the transaction.

6. Communication and confirmation

Following the authorization, the issuing bank’s decision is sent back through the acquirer and the payment gateway.

The customer and the merchant are notified about the authorization status (approved or declined).

7. Settlement (optional)

Lastly, we have this optional step.

If the transaction is approved, the funds are transferred from the customer’s account to the merchant’s account, typically within a few business days.

This process is known as settlement.

So, that’s how a seamless integration payment gateway works. With this out of the way, let’s look at some of the top payment gateway service providers.
