Migrating to Web SDK v1.1

​

What changed

• Yuno.initialize(), yuno.mountCheckout(), and yuno.startCheckout() now return Promises and must be awaited.
• continuePayment() is now required when sdk_action_required: true is returned from the payment API.
• Separate 3DS setup service calls are no longer needed — 3DS setup is now integrated into payment creation.

​

Steps

​

1. Update the script tag

<script src="https://sdk-web.y.uno/v1.1/main.js"></script>

​

2. Await all SDK method calls

const yuno = Yuno.initialize(publicApiKey, config)
yuno.mountCheckout({ checkoutSession, elementSelector: '#root', countryCode: 'US' })
yuno.startCheckout({ checkoutSession, countryCode: 'US' })

const yuno = await Yuno.initialize(publicApiKey, config)
await yuno.mountCheckout({ checkoutSession, elementSelector: '#root', countryCode: 'US' })
await yuno.startCheckout({ checkoutSession, countryCode: 'US' })

​

3. Implement continuePayment for dynamic flows

// After payment creation
if (paymentResponse.sdk_action_required) {
  const result = await yuno.continuePayment({
    checkoutSession,
    showPaymentStatus: true,
    yunoPaymentResult,
    yunoError,
    countryCode: 'US',
  })
  // result may contain a redirect object; handle appropriately
}

​

4. Remove separate 3DS setup calls

​
