Lite Web SDK v1.2 Changelog

Release Date: April 2025 Status: Previous version (superseded by v1.3)

What's New in v1.2

Version 1.2 builds on Lite v1.1's streamlined foundation with enhanced payment flow control capabilities and significantly expanded international language support.

Enhanced continuePayment Method

Expanded functionality allows dynamic configuration changes during payment continuation for more flexible implementations.

1. Extended continuePayment Functionality: Starting from version 1.2.0, the continuePayment method now accepts additional properties that were previously only available in startCheckout. This allows you to override specific configurations when continuing a payment.

New continuePayment Properties

Complete list of configuration options now available in continuePayment:

continuePayment({
  checkoutSession?: string
  showPaymentStatus?: boolean
  yunoPaymentResult?: (status: string) => void
  yunoError?: (message: string, data?: unknown) => void
  countryCode?: string
  language?: string
})

Enhanced Parameters:

• checkoutSession: Override the checkout session for the current payment
• showPaymentStatus: Control whether to show the Yuno Payment Status page
• yunoPaymentResult: Custom callback for payment result handling
• yunoError: Custom error handling callback
• countryCode: Specify country code during payment continuation
• language: Set language preference during payment continuation

Expanded Language Support

Significantly expanded international language coverage for global Lite SDK implementations:

• Core languages: Spanish (es), Portuguese (pt), Indonesian (id), Malay (ms), Thai (th)
• Asian languages: Filipino (fil), Chinese Traditional (zh-TW), Chinese Simplified (zh-CN), Vietnamese (vi), Korean (ko), Japanese (ja)
• European languages: French (fr), Polish (pl), Italian (it), German (de), Russian (ru), Turkish (tr), Dutch (nl), Swedish (sv)

Implementation Changes

Important considerations for Lite v1.2 implementation and migration.

Key Changes from v1.1

• Enhanced continuePayment: Method now accepts configuration overrides
• Expanded language options: Support for 18 languages vs. 7 in v1.1
• Backward compatibility: All v1.1 functionality remains supported

Script Tag

Updated script source for v1.2 functionality:

<script src="https://sdk-web.y.uno/v1.2/main.js"></script>

Example Usage

Demonstration of enhanced continuePayment capabilities in Lite SDK:

// Enhanced continuePayment with configuration override
yuno.continuePayment({
  checkoutSession: "438413b7-4921-41e4-b8f3-28a5a0141638",
  showPaymentStatus: true,
  yunoPaymentResult: (status) => {
    console.log("Payment completed with status:", status);
  },
  yunoError: (message, data) => {
    console.error("Payment error:", message, data);
  },
  countryCode: "US",
  language: "en"
});

Complete Implementation Example

Full Lite v1.2 implementation showing enhanced capabilities:

// Lite v1.2 implementation with enhanced continuePayment
const yuno = await Yuno.initialize(PUBLIC_API_KEY)

yuno.startCheckout({
  checkoutSession: "438413b7-4921-41e4-b8f3-28a5a0141638",
  elementSelector: "#root",
  countryCode: "FR",
  language: "fr",
  showLoading: true,
  issuersFormEnable: true,
  showPaymentStatus: true,
  card: {

  yunoPaymentResult: (status) => {
    console.log("Payment result:", status);
  },
  yunoError: (message, data) => {
    console.error("Payment error:", message, data);
  },
});

// Enhanced continuePayment with overrides
if (paymentResponse.sdk_action_required) {
  const result = await yuno.continuePayment({
    countryCode: "DE",
    language: "de",
    showPaymentStatus: false,
    yunoPaymentResult: (status) => {
      console.log("Payment continued with result:", status);
    }
