The CAPTCHA field allows you to add a captcha field to your form, to help protect your website from spam and bot abuse by trying to determine if the form is being submitted by a human, or defeating a form submission attempt by a scripted bot. The Gravity Forms Captcha field is available under the Advanced Fields section within the form editor.


Gravity Forms supports Google’s free reCaptcha service. There are different types of reCaptcha, and the Gravity Forms captcha field supports:

  • reCaptcha v2 Checkbox
  • reCaptcha v2 Invisible

Gravity Forms does not support v3 reCaptcha at this time.Support for the v2 Invisible reCaptcha type was introduced in Gravity Forms 2.4.7.

In addition to reCAPTCHA, the plugin Really Simple CAPTCHA may also be installed and activated for use within Gravity Forms. If you have this plug-in installed, you will be offered the option to use this type of captcha.

reCaptcha API Keys

A matched pair containing a site key and a secret key are required to link the reCaptcha service to your Gravity Forms site installation.

For Google reCaptcha, you will need to sign up for a free account to get your keys. From there, you can generate one or more pairs of the type of reCaptcha keys you wish to implement. reCaptcha v2 checkbox keys will only allow you to add a v2 checkbox on your form, while v2 Invisible keys will allow you to choose either v2 reCaptcha type. Older keys will not work.

Once you have your key pair, you will need to add them to the Gravity Forms Settings Page, and if appropriate, choose the type of reCaptcha you wish to use.

Note that this is a site wide setting, and as such, you cannot vary the reCaptcha type used from form to form on the same site.
