Google reCAPTCHA v3 is a new mechanism to verify whether the user is a bot or not. It has been designed for potential users, site owners that want more data about their traffic. Google reCAPTCHA v3 returns a score for each request without user friction. The score is based on interactions with your site and allows you to take appropriate action for your site.

Setting up your Google reCAPTCHA details in the config file

You have to register all details in the config for host_name, site_key, secret_key, and site_verify_url.
Register credentials in .env:

Specify your Score threshold and action in ‘setting’, e.g.

      'setting' =  [
          [
                'action' => 'contact_us', // Google reCAPTCHA required paramater
                'threshold' => 0.2, // score threshold
                'score_comparision' => false // if this is true, the system will do score comparsion against your threshold for the action
            ],
            [
                'action' => 'signup',
                'threshold' => 0.2,
                'score_comparision' => true
            ],
        ]

Note: if you want to enable Score Comparision, you also need to enable is_score_enabled to be true.

        ...
        'is_score_enabled' = true
        ...
