drupal-generics/invisible_recaptcha

Provides invisible recaptcha implementation.

invisible_recaptcha

The Invisible reCAPTCHA is a service that protects your site against spam, without using a challenge or a checkbox. The Invisible reCAPTCHA module adds the challenge div in the form and binds the submit button to the invisible_recaptcha library. On form submit, in javascript, the execute function is called on the "grecaptcha" object and a new field (g-reptcha-response) will be populated with the response from the reCAPTCHA API. Next, based on the value of the success attribute from the response, the submit process will continue, or an error will be set on the form, preventing it from being submitted., _(*1)

Invisible recaptcha configurations

1. In order to start using invisible reCAPTCHA you need to sign up for an API key pair for your site. Go to https://www.google.com/recaptcha/intro/index.html and click on the Get reCAPTCHA button. If you already have an Invisible reCAPTCHA key pair for your site go to step 2, else go in the Register a new site section and select the Invisible reCAPTCHA radio button. After registering the domain for your site you will get 2 keys, the site key and the secret key.
2. Go in the Configuration menu in Drupal and select Invisible reCAPTCHA configurations from the INVISIBLE RECAPTCHA tab. Here you must set the site key and the secret key and save the configurations.
