Properties

Property Usage

CAPTCHA Site Key (required)

CAPTCHA Secret Key (required)

The CAPTCHA secret key supplied by the CAPTCHA provider when you sign up for access to the API.

  • hCaptcha: https://hcaptcha.com/siteverify

CAPTCHA API URL (required)

The URL of the JavaScript that loads the CAPTCHA widget.

Class of CAPTCHA HTML Element

ReCaptcha V3 node

If you’re using Google reCAPTCHA, specify whether it’s v2 or v3. Turn on for v3.

Score Threshold

If you’re using Google reCAPTCHA v3, or hCaptcha, enter a score threshold.

The CAPTCHA provider returns a score for each user request, based on observed interaction with your site. CAPTCHA "learns" by observing real site traffic, so scores in a staging environment or in a production deployment that has just been implemented might not be very accurate.

A score of 1.0 is likely a good user interaction, while 0.0 is likely to be a bot.

The threshold you set here determines whether to allow or deny access, based on the score returned by the CAPTCHA provider.

Start with a threshold of 0.5.

For more information about score thresholds, refer to the Google documentation.
