# Introduction

> Meet RabbitPay — the 1-Click Checkout platform built for Shopify merchants.

<Note>
  **Welcome to RabbitPay.** This documentation covers everything you need to integrate 1-Click Checkout, partial payments, COD management, and the full RabbitPay API into your Shopify store or headless commerce stack.
</Note>

## What is RabbitPay?

RabbitPay is a **1-Click Checkout platform** purpose-built for Shopify merchants. It replaces multi-step checkout with a single tap, verified via OTP, and returns high- intent shoppers to purchase in under **7 seconds**.

RabbitPay handles:

* 1-Click Checkout with saved addresses and payment methods
* **Partial payments** (part prepaid, part COD)
* **COD** verification, RTO reduction, and risk scoring
* Native Shopify order sync via webhooks
* A unified REST API and SDKs for headless commerce

## How it works

<Steps>
  <Step title="Shopper lands on product page">
    RabbitPay renders a **Buy Now** button next to your existing Add to Cart.
  </Step>

  <Step title="One tap + OTP">
    Returning shoppers authenticate via mobile OTP. First-time shoppers add their details once — future purchases become truly one-click.
  </Step>

  <Step title="Payment or COD selection">
    Shoppers pick full prepaid, partial COD, or full COD (with risk scoring).
  </Step>

  <Step title="Order created in Shopify">
    RabbitPay creates the order via the Shopify Admin API and fires webhooks to your systems.
  </Step>
