Overview
API Keys
To use reCAPTCHA, you need to
sign up for API keys
for your site. The keys are unique to the domain or domains you specify, and
their respective sub-domains. Specifying more than one domain could come in handy
in the case that you serve your website from multiple top level domains (for
example: yoursite.com, yoursite.net).
By default, all keys work on "localhost" (or "127.0.0.1"), so you can always
develop and test on your local machine.
Integration
Once you've signed up for API keys, you can add reCAPTCHA to your site and customize the widget. If you're using one of the following programming environments or applications, click on the link below for further instructions.
