The withdrawal button has been mandatory since 19 June 2026 (a European obligation, in all 27 EU countries). Proof is what protects you. Here is how to install BackToMe on Shopify in 2 minutes. 1. In your BackToMe account, copy your tag. 2. Open your Shopify store admin. 3. Look for 'Themes' (Online Store menu). 4. On your published theme, open the '...' menu (three dots). 5. Click 'Edit code'. 6. Open the 'layout' folder, then the theme.liquid file, and find the </head> tag. 7. Paste the tag just before </head>, then click Save. 8. The button is live, bottom right by default. Its position can be adjusted in your BackToMe account. 9. Your customers can now withdraw in two clicks. The BackToMe difference: it is more than a button. Every withdrawal is timestamped, sealed with a SHA-256 fingerprint, confirmed on a durable medium and archived in the European Union for 5 years. Proof that holds up and strengthens the evidential value of your records (electronic proof admissible in all 27 EU countries). Installing the button covers the European obligation. Remember to update your terms and conditions too, to be fully compliant. 7-day free trial at backtome.fr.

Installation

Before copying the tag.

Check the required access, then use the location shown for your platform.

Prerequisites

  • An active Shopify subscription (the Basic plan is enough, no need for Advanced)
  • Administrator rights on the store (a Staff role with 'Manage themes' is enough)
  • An active theme you can edit. If your theme is locked by your agency, you will need to go through them

Location in Shopify

In the theme.liquid file of your active theme, just before the closing </head>

  1. 01Shopify admin > Online Store > Themes
  2. 02Find your active theme (the 'Current theme' badge)
  3. 03Actions (the three dots) > Edit code
  4. 04In the left-hand column, open Layout > theme.liquid
  5. 05Search for the </head> tag (Ctrl+F in the editor), paste the tag just before it, and click Save

Copy your BackToMe tag

Replace YOUR_ID with the shop identifier shown in your account.

Save and publish

The change must be published on the version your customers actually see.

Tag to copy into the <head>

<script async src="https://backtome.fr/widget.js" data-site="YOUR_ID"></script>

Over time

What removes the button from a Shopify theme

An update or theme change can remove a script that worked until then.

  • Publishing a different theme. The tag lives in the published theme’s theme.liquid, not in the shop: the theme next door does not have it.
  • A theme update from its developer, which replaces the theme files and your changes with them.
  • Publishing a duplicate made before you added the tag: it predates it.

BackToMe tracks the last signal received

The dashboard shows the tag’s last detection. If the button disappears, you have a precise starting point for checking the shop.

Verification

Check the published shop.

Do not stop at the editor’s confirmation. Open the public site and check what is actually loaded.

Expected result

The status changes to Detected in BackToMe and the button appears on the public shop.

  1. 01Open a private window.
  2. 02Load a public page of the shop.
  3. 03Check the button position and label.
  4. 04Open the form without submitting a real request.

After the click

Every request joins a verifiable case.

BackToMe records the request, sends the acknowledgement and keeps the information needed for tracking. The certificate states exactly what can be checked.

Troubleshooting

The most common blockers.

Every answer can be closed and used from the keyboard.
Duplicate the theme before editing
Before making any change, use Actions > Duplicate on your active theme to create a backup. If the installation ever causes a problem, you can revert to the duplicated theme in one click.
The button does not appear in the native checkout
The Shopify checkout is served in a secure iframe that scripts injected into theme.liquid cannot reach. The button will be visible on product, cart, blog and account pages, but not during the payment funnel, which is compliant with the button obligation (the button must remain accessible after the purchase, not during it).
Check that it really is the active theme
If you have several themes (test, backup, seasonal), edit the one marked 'Current theme'. Otherwise the tag will be pasted correctly but on a theme your visitors never see.
The button does not appear after publishing
Open the Shopify shop in a private window. Then check the published theme, tag identifier and its position in the head.
The status remains Not detected
The tag reports when a public page loads it. Visit the published shop in a private window, then refresh the status in BackToMe.
The form does not open
Test without browser extensions. Also check the CSP policy and any tool that blocks third-party scripts.
Can I give the installation to my developer?
Yes. Send them the tag and this guide. They do not need access to your account to add the line to the site.
