How can I implement reCAPTCHA v3 on my Webflow sites?
TL;DR
- Obtain the Site Key and Secret Key from Google reCAPTCHA by signing in and registering your site.
- Insert the Site Key into Webflow's "Integrations" tab under Project settings.
- Use a third-party service or webhook for Secret Key verification, as Webflow doesn't support custom server-side code.
- Add reCAPTCHA script to the "Custom Code" section in Project Settings, replacing with your Site Key.
- Publish and test your Webflow site to ensure reCAPTCHA is functioning properly.
To implement reCAPTCHA v3 on your Webflow site, follow these steps to enhance your form's security without interrupting user experience.
1. Obtain Site Key and Secret Key
- Sign into your Google account and visit the Google reCAPTCHA page.
- Navigate to v3 Admin Console and click on the “+” icon to create a new reCAPTCHA.
- Register your site by entering a label, choosing reCAPTCHA v3, and adding your domain.
- Save your settings to obtain the Site Key and Secret Key.
2. Insert reCAPTCHA Site Key into Webflow
- Go to Webflow and open the Designer.
- Select the ‘Project settings’ for the site where you want to add reCAPTCHA.
- Navigate to the “Integrations” tab.
- Paste the Site Key into the designated reCAPTCHA field in Webflow.
3. Integrate Secret Key on Backend
- Since Webflow does not support custom server-side code, you will need to use a service like Zapier, Integromat, or create a webhook to your own server to verify the Secret Key.
- Configure the webhook or service to verify the token returned by reCAPTCHA using your Secret Key.
4. Add reCAPTCHA Script to Custom Code
- Go to the Project Settings, then click on “Custom Code”.
- Under the “Head Code” section, add the script:
<script src="https://www.google.com/recaptcha/api.js?render=yoursitekey"></script>. - Replace
yoursitekeywith your actual Site Key. - Save the changes.
5. Customize Your Form
- Edit your form within Webflow Designer.
- You do not need to add any visible element for reCAPTCHA v3, as it runs in the background.
6. Publish and Test Your Site
- Publish your Webflow site to apply the changes.
- Test the form to ensure submissions work correctly and that reCAPTCHA is active (look for a reCAPTCHA badge).
Summary
To implement reCAPTCHA v3 on Webflow, you'll need to get your Site Key and Secret Key from Google reCAPTCHA, configure them in Webflow, and utilize additional tools to handle server-side verification. Make sure the script is added to the custom code section and that everything is correctly set before publishing your site.
