With this article, we want to delve deep into the world of UPI payment gateways, unraveling the various facets of integration and exploring its profound significance. From its pivotal role in promoting financial inclusion to security and efficiency, we will elucidate why UPI integration is not just an option but a strategic necessity for businesses seeking success in India’s dynamic digital economy.

Understanding UPI Payment Gateway Integration

UPI payment gateway integration enables a merchant to collect UPI payments from its customers through its website or app. In order to understand UPI payment gateway integration, let’s first look at all the entities involved in this integration process:

Third-Party Application Provider (TPAP) - TPAPs, as the name suggests, build and provide UPI-based applications to the payer. TPAPs like Amazon Pay, Google Pay, etc., onboard users on their applications and enable them to make payments through UPI.

Payment Service Provider (PSP) - PSPs are intermediaries that act as a bridge between the UPI network and the users. PSPs use their own app or a TPAP to onboard users on the UPI platform. If you are a UPI user, you can see a suffix attached to your VPA, for example, @axisbank, @ybl, etc. This suffix is generated by the PSP after onboarding.

Similarly, PSPs are also responsible for onboarding merchants and enabling them to collect UPI payments. PSPs provide merchants with credentials like merchant UPI ID, MCC code, etc., which the merchants can use to start API integration and collect payments post-integration.

National Payments Corporation of India (NPCI) - NPCI acts as an administrator of the UPI platform. It is responsible for defining the rules, regulations & guidelines of UPI. NPCI defines the roles and limitations of all the entities involved in the UPI ecosystem to offer a secure, efficient, and reliable UPI network to the users.

Now that we have explained the UPI payment gateway integration and the entities involved in it. Let’s take a look at different types of UPI payment gateway integration:

Types of UPI Payment Gateway Integration

UPI payments can be collected by any website/app in three ways. Let’s look at the different types of UPI integration that a UPI payment gateway can provide -

1. UPI collect - UPI collect flow is a type of UPI integration where the payee initiates the transaction; for example, if a customer is making a payment on an online shopping website/app, the website/app will create a UPI collect request, the customer will then have to enter their VPA and complete the payment.

Let’s take a look at the entire UPI collect flow -

Step 1 - Once the customer lands on a payment page, the first step is to enter a valid UPI Virtual Payment Address (VPA)

Step 2 - A payment request is then triggered by the UPI payment gateway along with a notification by the UPI Payment Service Provider (PSP) to the entered UPI VPA

Step 3 - The customer needs to accept the payment request and complete the transaction by entering their MPIN (Mobile Personal Identification Number)

Step 4 - Once the customer makes the payment, he/she then has to manually go to the respective website/app to check if the merchant has received the payment.

This type of payment integration provided by the UPI payment gateway has a tedious flow as the effort put in by the customer to complete the payment is high. There are various touch points like entering the VPA or accepting the payment request sent on a UPI PSP app like Google Pay, PhonePe, Paytm, etc, where the customer can drop off before completing the payment.

2. UPI intent - UPI intent, as the name suggests, is initiated by the payer. This type of UPI integration uses UPI Payment Service Provider (PSP) apps like Google Pay, PhonePe, Paytm, etc., already installed on a payer’s device to complete payment.

Once the customer lands on the payment page of a website/app, the customer is automatically redirected to their selected UPI PSP app where they can complete the payment, post that the customer will be auto-redirected back to the website/app. This type of UPI payment integration provides the customer with a higher level of convenience as it reduces the number of touch points where the customer can drop off.

3. UPI plug-in SDK - UPI plug-in SDK is the latest addition to the UPI payment gateway integration ecosystem. It enables businesses to collect payments within their app. This is the most convenient way for customers as it allows them to make payments in just two steps, reducing the time taken to complete the payment to just 5 seconds.
