Protecting your forms from spam and bot submissions is essential for maintaining the quality of your form data. In this guide, we'll explore how to effectively integrate Google reCAPTCHA with Static Forms to secure your forms without compromising user experience.

Why Use reCAPTCHA?

reCAPTCHA offers several advantages for form protection:

  • Bot Detection: Effectively identifies and blocks automated submissions
  • User Experience: Modern versions (reCAPTCHA v3) can work invisibly without user interaction
  • Accessibility: Provides audio alternatives for users with visual impairments
  • Adaptability: Adjusts security levels based on user behavior

Setting Up reCAPTCHA

Step 1: Get Your reCAPTCHA Keys

  1. Go to the Google reCAPTCHA Admin Console
  2. Sign in with your Google account
  3. Click on the "+" icon to create a new site registration
  4. Choose the reCAPTCHA type (v2 "I'm not a robot" Checkbox is recommended for most uses)
  5. Add your domains (the sites where the reCAPTCHA widget will run)
  6. Accept the Terms of Service and click "Submit"
  7. You'll receive a Site Key and a Secret Key - you'll need both

Step 2: Configure Your Form

Add the reCAPTCHA script to your page's <head> section:

HTML

Then add the reCAPTCHA widget to your form:

HTML

Be sure to replace:

  • YOUR_SITE_KEY with your reCAPTCHA Site Key
  • YOUR_API_KEY with your Static Forms API key

Important: Your reCAPTCHA Secret Key should be configured in your Static Forms dashboard, never in client-side code.

Best Practices

Position the CAPTCHA Strategically

Place the reCAPTCHA widget near your submit button to ensure users complete it before submission. This reduces form abandonment due to confusion about the submission process.

Style the Widget to Match Your Site

While you can't completely customize the reCAPTCHA widget, you can adjust its theme to match your site's design:

HTML

Choose between light (default) and dark themes.

Monitor Effectiveness

After implementing reCAPTCHA, monitor your form submissions to ensure:

  1. Legitimate users aren't being blocked
  2. Spam submissions have decreased
  3. The user experience remains smooth

Consider Invisible reCAPTCHA for Advanced Cases

If you want to minimize user friction even further, consider using reCAPTCHA v3 or the invisible version of v2. These versions don't require direct user interaction but might require additional JavaScript implementation.

reCAPTCHA v3 (Paid Plans)

Static Forms also supports reCAPTCHA v3, which provides invisible bot detection without requiring user interaction. Key differences:

Feature v2 v3 (Paid Plans)
User Interaction Required (checkbox) None (invisible)
User Experience Some friction Completely seamless
Detection Method Challenge-based Score-based (0.0-1.0)
Availability All users Paid plans (Pro/Advanced)

For more information on implementing reCAPTCHA v3, see our reCAPTCHA v3 guide.

Troubleshooting Common Issues

The reCAPTCHA Widget Doesn't Appear

  • Verify that the Google reCAPTCHA script is properly loaded
  • Check for JavaScript console errors
  • Ensure your site key is correct

Form Submissions Are Rejected

  • Confirm your Secret Key is correct in the form configuration
  • Make sure users are completing the CAPTCHA challenge
  • Verify that your domain is properly registered in the reCAPTCHA console

Users Report Difficulty Completing CAPTCHAs

  • Ensure the widget is visible and not obscured by other elements
  • Consider switching to a less strict CAPTCHA type
  • Provide clear instructions for users

Integrating reCAPTCHA with Static Forms provides an effective defense against spam while maintaining a good user experience. By following the steps and best practices outlined in this guide, you can secure your forms without adding unnecessary friction to the submission process.
