Complete Guide to Payment Gateway Integration for Indian Businesses

A payment gateway is the technology that securely processes online payments. For Indian businesses, choosing the right gateway affects customer experience, conversion rates, and operational efficiency.

1. Customer enters payment details on your website
2. Gateway encrypts and transmits data securely
3. Payment processor communicates with banks
4. Transaction approved or declined
5. Confirmation sent to you and customer
