    payload: [
      {
        vendor_code: 'vendor_code', // type string,
        quantity: 1, // type number,

    ],
  }, '*');
});

or

window.addEventListener('message', (event) => {
  if (event.data && event.data.eventName === 'iframeLoaded') {
    window.frames.wizartFittingRoom.postMessage({
    eventName: 'setShoppingCartStore',
    payload: [
      {

Example:

Code Block

language	js

window.frames.const wizartFittingRoom = document.getElementById('wizart-fitting-room-object');
wizartFittingRoom.onload = (() => {
    // Calling the event of getting the list of products from the shopping cart.
    window.frames.wizartFittingRoom.postMessage({
      eventName: 'getShoppingCartStore'
    }, '*');
});
  
// Subscription to the event of getting the list of products from the shopping cart.   
window.addEventListener('message', (event) => {
  if (event.data && event.data.eventName === 'getShoppingCartStore') {
    // Event handling
  }
}, false)

Data format:
event.data = {
  eventName: 'getShoppingCartStore',
  payload: [{ 
    vendor_code: 'vendor_code', // type string
    quantity: 1, // type boolean
    sku: 'sku', // type string
  }],
}
