Setting up the withdrawal button in Shopify – without code

The withdrawal function arrives in the theme through an app. Shopify's own return and cancellation rules can, per Shopify, help meet the obligation – the § 356a function itself (button, form, acknowledgement with content, date and time) is what you set up here with e-Widerruf, from install to test run.

In four steps

1. Install the app

   Install e-Widerruf from the Shopify App Store. The Free plan starts automatically – free forever, no payment method, and already covers the statutory function.

2. Enable the button in your theme

   The button is a theme extension (app embed): in the theme editor (Online Store → Themes → Customize) open the app embeds, switch on e-Widerruf, save. Position and label are set there – as a floating button or a footer link. Font and button style are inherited from your theme; there is nothing to rebuild.

3. Check e-mail delivery

   The app sends the acknowledgement automatically from an authenticated sender address; the sender name shown is your store name, and replies go to your contact address. Take a moment in the settings to confirm both.

4. Set the period and run a test

   Set the withdrawal period (default 14 days, the statutory minimum – longer is allowed, shorter is not). Then open your store, click the button, submit a test withdrawal: the acknowledgement should be in your inbox and the case in the dashboard, complete with the automatic deadline check.

How to tell a sound implementation

• The acknowledgement confirms receipt only – not the validity of the withdrawal.
• The button works without login, including for guest orders.
• The acknowledgement contains the content, date and time of the declaration.
• The form does not require a reason as a mandatory field.
• Cases are documented (audit log), so you have evidence in a dispute.

These points are the standard in e-Widerruf, on every plan.

One more thing if you sell across borders

The button, the form and the acknowledgement should reach the customer in the customer's language. A localised form paired with a mandatory notice in a foreign language is a gap that is easy to overlook – and the notice about receipt rather than validity is precisely the part that has to be understood. e-Widerruf serves the flow in 24 EU languages.
