Payment Gateway Sample Apps

This repository contains sample applications that demonstrate how to integrate Cashfree Payments Payment Gateway across backend frameworks, frontend stacks, mobile-friendly web apps, and language-specific SDK examples.

Each sample lives in its own folder and usually includes setup steps, required credentials, and a basic payment flow using Cashfree PG test mode.

Getting Started

1. Clone this repository.
2. Open the sample folder that matches your preferred tech stack.
3. Follow the setup instructions in that sample's local README.md.
4. Add your Cashfree PG credentials and run the app locally.
