This is the real component. Click to open the checkout.

UPayButton · $1.00

React component

The publishable key and amount are all it needs. Add settle to override which token this button settles in — otherwise it uses whatever you set in dashboard Settings.

import { UPayButton } from 'upay-arc-sdk'

<UPayButton
  apiKey="pk_test_..."
  amount={40}
/>

JavaScript, no React

Create a session and open the checkout in a popup, from any browser JS context.

import { UPay } from 'upay-arc-sdk'

const upay = new UPay({ apiKey: 'pk_test_...' })
const session = await upay.createCheckout({ amount: 40 })
upay.openCheckout(session.id)

Server-side session

Create a session server-side and redirect the customer to it — no client-side SDK needed at all.

import { UPay } from 'upay-arc-sdk'

const upay = new UPay({ apiKey: process.env.UPAY_API_KEY })
const session = await upay.createCheckout({ amount: 40 })
return redirect(session.checkoutUrl)
