Loyalty & Rewards: Redeeming Points on Checkout

  • Updated

Follow this guide to learn how to add a points redemption widget on the Shopify Plus checkout page.

Key Notes:

  • This guide is only applicable to Shopify Plus users
  • Starting August 2024, Shopify will discontinue support for the Checkout Slider widget due to compatibility issues; we recommend implementing the Variable Points Redemption widget to ensure you can still offer your customers the option to redeem points at checkout. 

In this Guide:

Note: Shopify is deprecating support for this widget starting August 2024.

  1. Create a snippet "stamped-checkout-slider" file with the following code content:
    • Replace "##storeHash##" with your store hash as it appears on the dashboard under Settings > API Keys
    • Replace "##REPLACE_WITH_CAMPAIGN_ID##" with the spending campaign's ID with the "variable" type. You will find the campaign ID in the tail-end of the URL of the settings page for the relevant spending rule:


{% assign stamped_key_public = shop.metafields['stamped'].api_public %}
{% if customer %}
  {% assign stamped_key_secret = shop.metafields['stamped'].api_secret %}
  {% assign stamped_customer_accepts_marketing = customer.accepts_marketing %}
  {% assign stamped_customer_email = customer.email %}
  {% assign stamped_customer_first_name = customer.first_name %}
  {% assign stamped_customer_id = customer.id %}
  {% assign stamped_customer_last_name = customer.last_name %}
  {% assign stamped_customer_orders_count = customer.orders_count %}
  {% assign stamped_customer_tags = customer.tags | join: "," %}
  {% assign stamped_customer_total_spent = customer.total_spent %}
  {% assign auth_token = customer.id | append: customer.email | hmac_sha256: stamped_key_secret %}
{% endif %}

<div id="stamped-rewards-init" class="stamped-rewards-init"
  data-key-public="{{ stamped_key_public }}"
{% if customer %}
  data-customer-accepts-marketing="{{ stamped_customer_accepts_marketing | escape }}"
  data-customer-id="{{ stamped_customer_id | escape }}"
  data-customer-email="{{ stamped_customer_email | escape }}"
  data-customer-first-name="{{ stamped_customer_first_name | escape }}"
  data-customer-last-name="{{ stamped_customer_last_name | escape }}"
  data-customer-orders-count="{{ stamped_customer_orders_count | escape }}"
  data-customer-tags="{{ stamped_customer_tags | escape }}"
  data-customer-total-spent="{{ stamped_customer_total_spent | escape }}"
  data-key-auth="{{ auth_token }}"
{% endif %}
<div id="stamped-rewards-slider-range" class="order-summary__section" style="display:none;" data-type="apply-points">
	<div id="stamped-rewards-widget" data-widget-type="rewards-redeem-variable-slider" data-campaign-id="##REPLACE_WITH_CAMPAIGN_ID##" data-max-amount="{{checkout.total_price | divided_by:100.0}}"></div>


function myInit(){ 
		apiKey: '{{stamped_key_public}}', 
		sId: '##storeHash##' 
<script onload="myInit()" type="text/javascript" src="https://cdn1.stamped.io/files/widget.min.js">
<link rel="stylesheet" type="text/css" href="https://cdn1.stamped.io/files/widget.min.css">

<script type="text/javascript">
  StampedFn.on('stamped:init:starting', function(data){
    if(window.location.href.indexOf("checkout") > -1 && window.location.href.indexOf("thank_you") == -1) {
        if(jQueryStamped(window).width() < 999)

  StampedFn.on('stamped:rewards:redeemed', function(data){
    var selectorCodeInput = 'input#checkout_reduction_code';
    var jquery;
        if (window.jQuery) {
          jquery = window.jQuery;
        } else if (window.Checkout && window.Checkout.$) {
          jquery = window.Checkout.$;
    var couponCode = data.detail.rewardCampaignCoupon.couponCode;
    if (couponCode){
      var i = ["focus", "keypress", "input", "blur"];
      i.forEach(function(e) {
        var n = new CustomEvent(e,{
          bubbles: !0


To install the dropdown selection widget for fixed discounts, replace the value for the attribute data-widget-type with rewards-redeem-select-options instead.

2. In the "Checkout.liquid" theme file, insert the following codes just before the </body> tag:

{% include 'stamped-checkout-slider' %}
  • If you cannot locate the checkout.liquid file in the theme editor, you'll need to contact Shopify to enable to file to be editable
  • Any variable discount coupon redeemed through the slider widget that remains unused after 24 hours will be automatically voided
