From the [Google reCAPTCHA](https://www.google.com/recaptcha/intro/index.html) page: > reCAPTCHA is a free service that protects your website from spam and abuse. reCAPTCHA uses an advanced risk analysis engine and adaptive CAPTCHAs to keep automated software from engaging in abusive activities on your site. It does this while letting your valid users pass through with ease. Your site comes with the Google reCAPTCHA module pre-installed. ## Adding reCAPTCHA to web forms Google reCAPTCHA challenges are automatically added to web forms, so long as the reCAPTCHA module is properly configured. You do not need to take any steps to add a reCAPTCHA challenge to web forms. > **Note:** You will not see the reCAPTCHA challenge when logged in as an authenticated user. To test the web form with reCAPTCHA enabled, log out or enable your browser's privacy mode. ## Configuring the Google reCAPTCHA Module If Google reCAPTCHA is not enabled on your site please email your Drupal Contact at CCS or email to enable this feature. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ccsdrupalguide.uoguelph.ca/advancedguide/recaptcha.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
