Before integrating CAPTCHA Cat into your website, you need to create a site in the dashboard to get your credentials.
1. Add a New Site#
- Sign in to the Dashboard
- Click Add Site
- Enter a name for your site
- Optionally add your domains (e.g.,
example.com,*.example.com) - Click Create
2. Copy Your Site Key#
After creating the site, you'll see your Site Key. This is used in your frontend code:
<div class="captcha-widget" data-sitekey="YOUR_SITE_KEY"></div>The Site Key is safe to expose in client-side code.
3. Get Your API Key#
The API Key is used for server-side token validation. To get it:
- Go to API in the dashboard sidebar
- Click Generate API Key
- Copy the key immediately (it's only shown once)
Keep Your API Key Secret
Your API key should never be exposed in frontend code or committed to version control.
