How to Add a Cookie Banner on Square Online

Last updated Mar 15, 2026

This guide walks you through adding the Kukie.io cookie consent banner to your Square Online store. Square Online provides a code injection feature that lets you add custom scripts to every page.

Prerequisite: You need a Kukie.io account and at least one site added. If you haven't done this yet, follow Create Your Account & Add Your First Site first.

Step 1: Get Your Embed Code

Log in to your Kukie.io dashboard, navigate to your site, and copy the embed code from the Setup tab. It looks like this:

<script src="https://cdn.kukie.io/s/YOUR-SITE-KEY/c.js" async></script>

Replace YOUR-SITE-KEY with the actual site key shown in your dashboard.

Step 2: Add the Script to Square Online

  1. In your Square Dashboard, go to Online → Website (or Square Online)
  2. Click Website → Pages, then click the ... menu and select Website Settings
  3. Scroll down to Advanced and find Code Injection (or Header Code)
  4. In the Header section, paste: 
    <script src="https://cdn.kukie.io/s/YOUR-SITE-KEY/c.js" async></script>
  5. Click Save and Publish your site

Square Online plan required: Code injection is available on Square Online Plus and Premium plans. If you are on the free plan, you may need to upgrade to add custom scripts.

Step 3: Verify the Installation

Visit your website in a new browser window (or incognito/private mode). You should see the Kukie.io consent banner appear. If it does not show, check the following:

  • Open your browser's Developer Tools (F12) and look for the script in the Network tab — it should load with a 200 status
  • Check the Console tab for any JavaScript errors
  • Make sure you published/saved your changes in Square Online
  • Clear any platform-level cache if applicable

For a detailed verification walkthrough, see How to Verify Your Banner Installation.
