As the global trend increasingly favours online shopping over traditional brick-and-mortar stores, Payment Gateways have become an integral part of our lives. Whether you are purchasing your favourite pair of shoes from an online shopping site, booking flight tickets for your next trip, or subscribing to a monthly OTT service, the process of transferring money electronically is facilitated by a vital component known as the Payment Gateway.
Payment gateways are the front-end checkout interface, or that ‘customer-facing checkout’ where customers enter their payment information. They also do a handful of other crucial things for businesses to take payments quickly and securely – such as data encryption, payment authorisation, tokenisation, fraud prevention and data reporting.
This blog will explain how the payment gateway process works, the vital role of a payment processor, and the steps involved in setting up a payment gateway.
What is a Payment Gateway?
A payment gateway is the technology responsible for authenticating and securely transmitting payment data between different parties involved in the payment process.
A payment gateway will usually also incorporate various security measures like encryption, tokenisation, and fraud management solutions. Further to this, gateways must follow a strict set of procedures as per the PCI DSS compliance standard. This includes annual audits and recertifications to ensure the standard’s validity.
How does a Payment Gateway work
Before entering the payment gateway integration process, it’s essential to understand how the payment gateway working process is. Payment gateways exist in two primary forms: offline (point-of-sale, or POS) gateways and online payment gateways.
1. POS (Offline) Payment Gateways
A physical payment gateway is typically the Point of Sale (POS) system you see at retail stores. These systems are connected to card readers or terminals that enable customers to make payments using debit/credit cards or digital wallets, in person. The POS gateway securely transmits payment data from the terminal to the bank or payment processor, authorising the transaction on the spot.
2. Online Payment Gateways
On the other hand, an online payment gateway is designed to handle transactions made through websites, e-commerce platforms, and mobile applications. When a customer enters their payment details during checkout, the gateway encrypts the information and forwards it securely to the bank or payment processor for approval. This ensures seamless and secure transactions for online businesses.
A payment gateway follows these steps:
Step 1: Customer initiates a payment
The customer enters their payment details (card number, CVV, expiry date, etc.) at checkout—either through a website, mobile app, or POS terminal.
Step 2: The Business sends details to the payment gateway
The merchant’s system securely transmits the encrypted payment details to the payment gateway for processing.
Step 3: Gateway forwards to the payment processor
The payment gateway passes the information to the payment processor, which acts as the intermediary between the business and the card networks.
Step 4: The processor connects with the card network (E.g., Visa, Mastercard).
The processor routes the transaction to the relevant card scheme, which then forwards it to the customer’s issuing bank.
Step 5: Issuing bank performs checks
The customer’s bank verifies details such as account balance, card validity, and fraud checks, as well as daily transaction limits, to decide whether to approve or decline the transaction.
Step 6: Response flows back through the chain
The approval or decline decision travels back from the issuer, through the card network, processor, and gateway—ultimately reaching the business and the customer in real-time.
Step 7: Funds are transferred if approved
If approved, the money is transferred from the customer’s issuing bank to the acquiring bank (the merchant’s account) and then into the business’s bank account, typically within 1–2 business days.
A payment gateway plays a pivotal role in facilitating secure and seamless online transactions. Other benefits of using a payment gateway include enhanced customer trust, hassle-free international transactions, and a 24/7 payment facility.
The Role of the Payment Processor
Although the payment gateway provides a safe route for the transaction data, the payment processor can be considered the engine itself that moves the money backstage. It communicates with card networks, acquiring banks and issuing banks to certify and execute the payment. The payment gateway cannot ensure transactions without directing operations through effective payment processors. The processor, in a nutshell, performs the operations, while the payment gateway handles the technical, security, and customer-oriented elements.
The Payment Gateway Integration Process

The payment gateway manages the front-end checkout experience, while the payment processor handles the back-end financial transactions.
2. Is SabPaisa safe for handling private payment data?
Of course. SabPaisa operates safe AWS servers that are PCI-DSS certified and compliant with ISO/IEC 27001:2022. We adopt all RBI policies.
3. What are the different kinds of payment gateways?
The payment gateways come in 4 different types with individual functionalities. Hosted Gateways provides customer redirection, security and compliance. Self-hosted adds control and rapid checkout, and the API-hosted adds customisation and integration convenience. Bank links open with local gateways but are not scalable.
