@inttegro/js

Controlled-origin loader and TypeScript types for mounting an Inttegro-hosted Checkout experience. This npm package does not contain the executable checkout runtime. loadInttegro() downloads it from the fixed, Inttegro-controlled URL https://js.inttegro.com/inttegro.js@<package-version>.

import { loadInttegro } from '@inttegro/js'

const inttegro = await loadInttegro()
if (!inttegro) throw new Error('Checkout requires a browser')

const checkout = inttegro.createCheckout({ orderId: 'or_...' })
checkout.on('completed', () => {
  window.location.assign('/order-complete')
})
await checkout.mount('#checkout')
Copy

Use the managed modal when Checkout should open above the current page:

checkout.on('canceled', () => showPaymentOptions())
await checkout.present()
Copy

No application dialog, modal CSS, focus trap, or scroll locking is required. Call checkout.dismiss() to close the managed modal programmatically.

The runtime URL is not configurable. Do not bundle, mirror, proxy, or self-host it. The mounted iframe is hosted by Inttegro Pages. A restrictive Content Security Policy must allow script-src https://js.inttegro.com and frame-src https://pages.inttegro.com. When using CSP nonces, pass the current request nonce to loadInttegro({ nonce }).
