Free reCAPTCHA Webflow integration

As businesses grow and more people engage with their websites, the risk of spam submissions on forms becomes an ever-present concern. To ensure that your forms remain secure and that only legitimate submissions make it through, Google reCAPTCHA has become a go-to solution. Implementing reCAPTCHA on Webflow forms is a straightforward process, but it requires a clear understanding of the steps involved. In this comprehensive guide, we’ll walk you through how to properly implement reCAPTCHA on Webflow forms, so you can protect your website and enhance the user experience.

Whether you’re running a contact form, newsletter sign-up, or any other type of Webflow form, adding reCAPTCHA is essential for preventing spam and bots. This tutorial is tailored for both Webflow beginners and experienced developers who want to safeguard their forms and keep their website’s data integrity intact.

What is reCAPTCHA and why should you use it

eCAPTCHA is a free service offered by Google that helps protect your website from spam and abuse by ensuring that only real users can submit forms. It works by presenting users with challenges that are easy for humans but difficult for bots to complete, such as identifying objects in images or simply verifying that they are not a robot.

Implementing reCAPTCHA on Webflow forms provides a few key benefits:

• Prevent spam submissions: Bots are commonly used to flood forms with unwanted submissions. reCAPTCHA blocks this.
• Protect Sensitive Data: By ensuring that form submissions come from real users, reCAPTCHA reduces the chances of malicious attacks, such as scraping or phishing.
• Improved Form Integrity: With less spam, your form submissions remain more accurate and reliable, improving your follow-up process and overall data quality.

Now that we’ve covered the importance of reCAPTCHA, let’s dive into the steps to properly implement it on Webflow forms.

Step 1 - Set up reCAPTCHA with Google

Before you can add reCAPTCHA to your Webflow forms, you need to set it up with Google. Follow these simple steps:

1. Go to Google to reCAPTCHA website
   Visit the Google reCAPTCHA website.
   ‍
2. Sign in to your Google account
   If you’re not already signed in to your Google account, do so.
   ‍
3. Register a new site
   On the reCAPTCHA dashboard, click on the “+” button to register a new site. You will need to provide your website’s details, such as the domain name.
   ‍
4. Select reCAPTCHA version
   Choose reCAPTCHA v2 (“I’m not a robot” checkbox) or reCAPTCHA v3 (invisible reCAPTCHA). We recommend reCAPTCHA v2 for Webflow forms, as it provides a clear and familiar user interface.
   ‍
5. Copy Site Key and Secret Key
   After registering your website, Google will provide you with a Site Key and a Secret Key. These keys are essential for integrating reCAPTCHA with your Webflow form. Make sure to copy both for use in the following steps.

‍

Step 2 - Add reCAPTCHA to your Webflow form

With your reCAPTCHA site key and secret key in hand, you can now add it to your Webflow form. Here’s how to do it:

1. Open your Webflow project
   Log in to your Webflow account and open the project where you want to add reCAPTCHA.
   ‍
2. Go to the form settings
   Navigate to the page that contains the form. Select the form you want to secure with reCAPTCHA.
   ‍
3. Add embed code to your form
   - Open the Form Block in the Designer.
   - Add an Embed Code element below the form fields (or wherever you’d like the reCAPTCHA checkbox to appear).
   - Paste the code that you downloaded from this form.
   ‍
4. Replace "YOUR_SITE_ KEY"
   Replace the "YOUR_SITE_KEY" with the actual Site Key you copied from Google earlier.
   ‍
5. Publish your site
   Save your changes and publish your Webflow project. At this point, you will see the reCAPTCHA checkbox appear on your live form.

‍

Step 3 - Configure form sumission settings

Next, you’ll need to configure your form’s submission settings to verify that the user has completed the reCAPTCHA challenge. Here’s how to do this:

1. Go to the form action settings
   - Open the form settings in Webflow.
   - Under the Form Settings, ensure that the form action is set to either email, Webhook, or the appropriate submission target.
   ‍
2. Add custom code to verify reCAPTCHA
   In the form submission settings, add custom code to verify the reCAPTCHA challenge. This code communicates with Google’s servers to check whether the form submitter is human. Add the PHP or server-side verification code you downloaded from this from.
   ‍
3. Replace "YOUR_SECRET_ KEY"
   Replace the "YOUR_SECRET_KEY" in the code with the Secret Key you obtained from Google. This ensures that the verification is conducted securely.
   ‍
4. Test the form
   Submit the form to ensure that the reCAPTCHA challenge is working correctly. If you see the confirmation or error message related to reCAPTCHA, your form is successfully secured.
   ‍

Step 4 - Monitor form sumission for accuracy

Once you’ve implemented reCAPTCHA on your Webflow forms, it’s important to monitor the form submissions for accuracy. This will help you ensure that legitimate users are not facing issues with the form and that spam submissions are effectively blocked.

Use Google reCAPTCHA analytics

Google provides an analytics dashboard where you can monitor the performance of your reCAPTCHA implementation. You can see how many successful verifications have occurred and spot any issues with users having trouble completing the challenge.

Conclusion

Protecting your Webflow forms from spam and bot submissions is crucial to maintaining the integrity of your site’s data. By following the steps outlined above, you can successfully implement Google reCAPTCHA to secure your forms and prevent abuse.
