Adding Captcha to WordPress – Understanding reCAPTCHA v3

reCAPTCHA v3 represents a significant upgrade over previous versions. It introduces advanced risk analysis that runs constantly behind the scenes without any user interaction required. The risk can be averted by adding Captcha to WordPress.

Whereas reCAPTCHA v2 used visible challenges like selecting images or clicking a checkbox, v3 is entirely invisible to legitimate human users. Based on sophisticated bot detection heuristics, it simply generates a spam score between 0 and 1 for each form submission.

If a score falls below your configured threshold, the submission is blocked as likely spam. For users, the form behaves normally with no visible reCAPTCHA elements. Adding Captcha to the WordPress online booking forms significantly improves form conversion rates. Moreover, it still provides robust protection according to Google’s benchmarks.

For Gravity Forms Booking, integrating reCAPTCHA v3 is a no-brainer.

Setting Up reCAPTCHA v3 for Your Website

To start using reCAPTCHA v3, you’ll first need to sign up for reCAPTCHA and configure the credentials in your website code. Here are the steps:

Go to the Admin Console and create a new reCAPTCHA v3 site key
Under Domain Verification, add each domain that will use reCAPTCHA
Click Submit to receive your Site Key and Secret Key

Now, we can install and configure the Gravity Forms reCAPTCHA v3 add-on using these credentials:

And that’s it! With the add-on installed and configured, we can now add reCAPTCHA v3 protection to forms.

Implementing reCAPTCHA v3 in Gravity Forms

Gravity Forms makes it easy to add reCAPTCHA v3 using the visual form editor or coded Form Editor. Let’s go through both methods.

For developers who prefer customization, you can add reCAPTCHA v3 directly in the code:

On the form, click Form Editor > Form Layout
Where you want the reCAPTCHA field, add:

[recaptcha type=”v3″ site_key=”your_site_key” data-theme=”light” data-size=”normal”]

replace your_site_key with your unique reCAPTCHA v3 site key
Customize with additional available parameters
Save and exit Form Editor

Now, your Gravity Form has the same seamless anti-spam protection using a coded approach.

Testing and Troubleshooting

Once added to your forms, it is crucial to test that reCAPTCHA v3 is working as expected:

Verify scores are displayed in Form Entries
Submit spam submissions and ensure they are blocked
Submit normal entries and confirm no reCAPTCHA interactions
Check for any JavaScript errors on the page

For any issues, first, ensure your Site Key and Secret Key are entered correctly in the Gravity Forms settings. Also, to add Captcha to WordPress, confirm your reCAPTCHA type, size, theme, and score threshold are configured.

Furthermore, refer to the Gravity Forms and Google reCAPTCHA documentation for more detailed troubleshooting steps.
