Documentation Overview

Churnkey SDK

A production-ready cancel flow for React. Open source. Optionally connects to Churnkey for analytics and AI-powered retention.

Packages

Package	Description
`@churnkey/react`	The cancel flow. Drop-in component, headless hook, or core state machine. React 18 and 19.
`@churnkey/node`	Server-side token generation. Only needed if Churnkey is handling billing actions for you, or if you're using the hosted embed.
`@churnkey/mcp`	Model Context Protocol server. Lets Claude, Cursor, and other AI agents query your Churnkey data (sessions, analytics, DSR) using a Data API key.

Quick start

Terminal

npm install @churnkey/react

server.ts

import { CancelFlow } from '@churnkey/react'
import '@churnkey/react/styles.css'

<CancelFlow
  steps={[
    {
      type: 'survey',
      title: 'Why are you leaving?',
      reasons: [
        {
          id: 'expensive',
          label: 'Too expensive',
          offer: { type: 'discount', couponId: 'STRIPE_SAVE20', percentOff: 20, durationInMonths: 3 },
        },
        { id: 'not-using', label: 'Not using it enough', offer: { type: 'pause', months: 2 } },
        { id: 'missing', label: 'Missing features' },
      ],
    },
    { type: 'feedback', title: 'Anything else?' },
    { type: 'confirm' },
  ]}
  handleDiscount={async (offer) => myBilling.applyCoupon(offer.couponId)}
  handlePause={async (offer) => myBilling.pause({ months: offer.months })}
  handleCancel={async () => myBilling.cancel()}
  onClose={() => setOpen(false)}
/>
