EU CAPTCHA for Shopify

Frequently Asked Questions

• How do I add EU CAPTCHA to a Shopify store?

  Edit your Shopify theme's Liquid templates to include the verify.js script and the EU CAPTCHA widget div with your sitekey in the forms you want to protect. On form submission, send the eu-captcha-response token to a serverless function or your own backend API for verification against the EU CAPTCHA endpoint before processing the request.

• Does EU CAPTCHA work with Shopify Liquid templates?

  Yes. Shopify themes use Liquid templates for rendering HTML. Add the verify.js script tag and the EU CAPTCHA widget div directly to the relevant Liquid section or snippet files for the forms you want to protect. The widget renders in the browser after Shopify's server-side Liquid rendering, which is the correct behaviour for a client-side CAPTCHA widget.

• How do I protect Shopify contact and newsletter forms with EU CAPTCHA?

  Edit the contact.liquid or newsletter.liquid section templates in your Shopify theme to include the EU CAPTCHA widget div. When the form is submitted, intercept it with JavaScript, extract the eu-captcha-response token, and send it to a serverless verification function before allowing the form to proceed. This works for both native Shopify forms and custom form implementations.

• Can EU CAPTCHA be used on a Shopify headless storefront?

  Yes. For headless Shopify storefronts built with Next.js, Remix, or Hydrogen, integrate EU CAPTCHA as you would in any React or JavaScript application. Load verify.js in the client-side component containing the form, read the token on submission, and verify it in your server-side API handler before passing the form data to the Shopify Storefront API.

• Does EU CAPTCHA work with Shopify's customer account forms?

  Yes. Shopify's customer login, registration, and password recovery forms use standard HTML form submission. Add the EU CAPTCHA widget to these forms by editing the relevant theme templates or using Shopify's Customer Accounts Extensibility features. Verify the token via a serverless function before the customer account action is processed.

• Does EU CAPTCHA slow down my Shopify store's page speed or Core Web Vitals?

  No. EU CAPTCHA's verify.js script is small and loads asynchronously, meaning it does not block page rendering or affect Shopify's Lighthouse scores or Core Web Vitals. The background verification runs independently and does not add any perceptible delay to the user's browsing or checkout experience.

• Is EU CAPTCHA GDPR compliant for Shopify stores targeting EU customers?

  Yes. EU CAPTCHA is operated by an EU-based company, is hosted entirely in Germany, and does not rely on US cloud providers or infrastructure subject to US surveillance laws. The service processes only the data necessary to provide and verify the CAPTCHA (such as IP address and technical browser or device information) in line with the requirements of the GDPR. Your organization remains responsible for providing transparent privacy information, selecting an appropriate legal basis, and obtaining any required consent for your specific Shopify implementation.
