The continuous and rapid digital advancement in the online payment solutions space has led businesses to constantly seek ways to simplify their business payment systems and provide a smooth and hassle-free experience to their customers. One such solution that has gained significant popularity in recent years is the advent of UPI payment gateways. Now purchasing things online is as easy as filling a glass of water for UPI users. 

But when it comes to the technical aspects of UPI payments, many businesses are still unaware of the nitty gritty. So today, in this article we will go in-depth and learn the various aspects of a UPI payment gateway, what it is, who the entities involved are, what are the types, how it can benefit businesses, and much more.

What is UPI Payment Gateway?

UPI, or Unified Payment Interface, is a real-time online payment solution developed by the National Payments Corporation of India (NPCI) in the year 2016, using this any user can link multiple bank accounts with a single mobile app. It’s a digital service that facilitates online transactions via the UPI infrastructure. It acts as a medium where, as soon as the customer clicks on the “Pay” button on their UPI app they are prompted to enter their MPIN, if the MPIN is correct then the payment gets deducted from the customer’s accounts, and gets transferred in real-time to the merchant’s account. In fact UPI digital payments in India is being adopted at such a rapid rate that by the year 2028, it is also projected that UPI is going to secure 90% of retail transactions.

Which are the Entities Involved in UPI Payment Gateway Integration?

The Merchants: These are the businesses, big or small, who want to offer UPI as a payment option on their website or mobile app. By integrating UPI, they cater to a wider customer base and provide a convenient checkout experience.

The Customers: These are the individuals who use UPI apps like PhonePe, Google Pay, or BHIM on their smartphones. With a few taps on their mobiles and by entering their MPIN, they can instantly pay for their purchases in the blink of an eye.

The Payment Service Provider (PSP): PSPs are the driving force behind the whole UPI online payment solutions. They provide the technology and infrastructure that allows merchants to integrate UPI into their platform. They act as a mediator, enabling communication between the customer’s UPI app, the bank network (governed by NPCI), and the merchant’s bank account.

The National Payments Corporation of India (NPCI): This is the governing body that oversees the entire UPI infrastructure in India. They set the rules, facilitate smooth operation, and ensure secure payment processing

The Banks: These are the financial institutions where both the customer and the merchant hold their bank accounts linked to their UPI apps. They ensure secure payment processing by transferring funds based on the instructions received through the PSP and NPCI network.

Types of UPI Payment Gateway Integrations

Integrating a UPI payment gateway into your business platform allows you to accept, and your customers to pay easily using their preferred UPI apps. However, with various integration options available, choosing the right one can be confusing. Below given are the three main types of UPI payment gateway integrations:

1. API Integration

API (Application Programming Interface) integration offers the most control and flexibility for developers. Here, the PSP (Payment Service Provider) provides a set of tools and instructions (APIs) that allow developers to build the UPI payment gateway directly into your website or mobile app. This approach gives you the freedom to tailor the checkout experience to match your brand’s design and functionality. 

2. Plugin Integration

For businesses using established platforms like WordPress or Shopify, plugin integration offers a simpler and faster solution. PSPs often provide pre-built plugins that can be easily installed on your website. These plugins handle the core functionalities of the UPI payment gateway, simplifying the integration process. This is a great option if you prioritize ease of use and don’t require extensive customization. However, plugins typically offer less flexibility compared to API integration. The look and feel of the checkout experience might be pre-determined by the plugin, potentially limiting your ability to fully integrate it into your brand’s aesthetic.

3. SDK Integration

For businesses seeking full control over the UPI payment gateway experience within their mobile apps or websites, SDK (Software Development Kit) integration is the way to go. PSPs provide SDKs, which are essentially toolkits that give developers the freedom to create their own custom payment gateway. This approach offers maximum flexibility and allows you to design a checkout flow that perfectly aligns with your specific needs and brand identity. However, similar to API integration, SDK integration necessitates a high level of development expertise. You’ll likely need an in-house development team or external developers to successfully implement this method.

Process of UPI Payment

Each type of integration follows a similar process:

• The customer selects UPI as the payment option at checkout
• Next, the customer can either enter their UPI ID/VPA and open the app associated with VPA to make the payment 
• Or the customer can select a specific UPI app like PhonePe, Google Pay, Paytm, etc
• In this case, the merchant’s platform redirects the customer to the PSP’s secure interface
• The customer chooses the bank account linked to their UPI app
• The customer enters their UPI PIN/MPIN to authenticate the transaction
• If successful, the funds are transferred from the customer’s bank account to the merchant’s bank account
• Both the merchant and the customer get real -time confirmation of the completed transaction

The adoption of UPI as a payment method has been nothing short of remarkable. With its convenience and ease of use, UPI has become a preferred choice for individuals and businesses. Integrating a UPI payment gateway on your website or mobile app offers several advantages:
