How can I install ReCaptcha v3 in Webflow to prevent spam through the contact form? The spam is coming from a sender named "Joe Miller" and it has been causing a nuisance. Thank you for any tips or advice.

TL;DR
  • Register your site with Google reCAPTCHA v3, obtain the Site Key and Secret Key, and add the reCAPTCHA script to your Webflow project's Custom Code section.  
  • Modify your contact form with a hidden input and JavaScript to handle the reCAPTCHA token, publish your site, and test for spam reduction.

Integrating ReCaptcha v3 into your Webflow site is a great way to prevent spam submissions like those from "Joe Miller." Here’s how you can add this functionality to your Webflow contact form.

​

1. Register Your Site with Google reCAPTCHA

  • Visit the Google reCAPTCHA website and log in with your Google account.
  • Register a new site by selecting reCAPTCHA v3.
  • Enter your domain name (e.g., yoursite.com) and accept the terms of service.
  • Copy down the Site Key and Secret Key provided by Google.

​

2. Add reCAPTCHA v3 Script to Webflow

  • In Webflow, go to your Project Settings.
  • Click on the Custom Code tab.
  • Paste the following script in the "Head Code" section:
  • <script src="https://www.google.com/recaptcha/api.js?render=yoursitekey"></script> (Replace yoursitekey with your actual Site Key).
  • Save the changes.

​

3. Modify Your Contact Form

  • Open your Webflow Designer and navigate to the page with your contact form.
  • Select the form element and open the Element Settings panel (shortcut ‘D’).
  • Add a new embed within the form and insert:
  • <input type="hidden" name="g-recaptcha-response" id="g-recaptcha-response">
  • Add a new JavaScript embed before the closing body tag using the following code:

  ```javascript

  <script>

  grecaptcha.ready(function() {

      grecaptcha.execute('yoursitekey', {action: 'submit'}).then(function(token) {

         document.getElementById('g-recaptcha-response').value = token;

      });

  });

  </script>

  ```

  (Replace yoursitekey with your actual Site Key).

​

4. Test Your Form

  • Publish your website to ensure all settings are live.
  • Visit your live site and submit a test form to make sure it works properly with reCAPTCHA.

​

5. Monitor and Adjust

  • Check your form submissions for any decrease in spam.
  • If needed, you can review the reCAPTCHA scores in the Google reCAPTCHA admin console.

​

Summary

To add ReCaptcha v3 to your Webflow contact form, register your site with Google reCAPTCHA, add the required script in the Head Code section, modify the form to include a hidden input for the reCAPTCHA response, and publish your changes. This setup can help reduce spam submissions effectively.
