This article explains what a payment gateway is, how it functions, the different types available, and how it compares to other payment solutions. Check your business loan eligibility to ensure your business is financially prepared to integrate such technologies.
What is a payment gateway?
A payment gateway is a technology that enables merchants to accept payments from customers through various digital methods such as credit/debit cards, UPI, net banking, and mobile wallets. It acts as a bridge between a customer’s bank and the merchant’s bank, ensuring that the payment process is smooth, secure, and efficient.
How does a payment gateway work?
Here’s how a typical payment gateway functions step by step:
- Step 1: The customer selects products/services and proceeds to checkout.
- Step 2: The payment gateway encrypts and transmits the customer’s payment data to the acquiring bank.
- Step 3: The acquiring bank routes the request to the payment processor.
- Step 4: The payment processor communicates with the customer’s issuing bank to approve or decline the transaction.
- Step 5: The response is sent back through the gateway, and the transaction is either approved or declined.
Step 6: If approved, funds are transferred to the merchant’s account.
Types of payment gateways
There are several types of payment gateways used by businesses in India:
- Hosted payment gateway: Redirects customers to the payment service provider’s page.
- Self-hosted payment gateway: Payment details are collected on the merchant’s site and then sent to the gateway for processing.
- API/Integrated gateway: Provides full control over the checkout process, ideal for larger businesses with development resources.
Mobile payment gateway: Optimised for mobile apps and supports UPI and wallet payments.

Difference between a payment gateway and a payment processor
While both are part of the payment ecosystem, their roles differ:
- Payment gateway acts as the communication channel between the merchant and banks. It handles data encryption and secure transmission of payment information.
- Payment processor is responsible for carrying out the actual transaction by communicating with banks and card networks to approve or decline the payment.
- Think of the gateway as the “interface” and the processor as the “engine” that makes the transaction happen.

A payment gateway is essential for any business that wants to accept digital payments securely and efficiently. From enhancing customer trust to enabling faster transactions, it plays a crucial role in business growth.
