Update List Item

Update product attributes like cprops, note.


Updates cprops, notes for List Item* or a product in a List** using the given lid and Product.


swat.updateListItem(lid, product, onSuccess, onError)


Here's an example of how you can use this API to update a List Item of the List with lid and with product object:

// Define the list id of the list to be updated
let lid = "59179e9f-139d-4857-bcdd-3ad88a38b47d"; // lid

// Define the product object
let product = {
  epi: epi,  // variant id of the product to be updated
  empi: empi, // product id of the product to be updated
  du: du, // canonical uri of the product to be updated
  qty: qty, // quantity
  note: note, //optional note
  cprops: {} // Optional custom attributes

// Define success callback 
let onSuccess = function(updatedListItem) {
  // executed when successfully updated a list item
	console.log("Successfully updated the List Item", updatedListItem);

// Define error callback 
let onError = function(error) {
	// Error is an xhrObject
	console.log("Error while updating the List Item", error);

// Update a list with the above callbacks, lid and product map
swat.updateListItem(lid, product, onSuccess, onError);


Things to consider

  1. The updates are limited only to the products inside the list.
  2. The cprops object has a limit; you cannot add an indefinite amount of data.
  3. cprops and note is meant only to be used for frontend implementations; we do not support any custom data on our backend; we depend on the platform to give us information.

API Parameters

lidguidUnique id of the List to be updated
productobjectPlease refer Product
onSuccessfunctionCalled when the List Item is successfully updated.
onErrorfunctionCalled when there is an error while updating the List Item.

Success Response

The success response contains information about the updated List Item like its empi, epi, product uri, image uri etc. and about the corresponding List, like lid, creation and update timestamps.

This information can be used to retrieve or manipulate the List Item in future API calls.
