Add the power of Google's invisible reCAPTCHA v3 to your store! reCAPTCHA v3 helps you detect abusive traffic on your website without any interaction required by the user. It assigns a score to the user's actions, which can then be used to block users who do not meet the score threshold. This extension is a standard Captcha type OpenCart extension that will show up in Extensions > Captcha, and you can assign it to your pages in System > Settings > Option tab.
NOTE: This extension does NOT work with Journal 3 because they do not utilize the OpenCart captcha system properly for all their forms. Do not purchase this extension if you're using Journal 3.
Upload and go — modifies no core files.
Set score thresholds individually for the OpenCart pages that support captchas (Account Registration, Contact Page, Guest Checkout, Product Reviews, and Returns).
Edit the error message directly in the extension admin panel.
Optionally fall back to reCAPTCHA v2 if the customer does not pass the v3 check.
Restrict the captcha to check only guests and/or specific customer groups.
Choose to ignore the captcha for certain IP addresses.
Includes a Testing Mode to view the reCAPTCHA results in the browser error console.
