InfoPeak Captcha stores nothing about your visitors: no IP address, no cookie and no row per visitor. You need a sitekey (public) and a secret (server only) from your Captcha dashboard.
1. Add the widget to your form
Load https://captcha.infopeak.io/infopeak-captcha.js and place <div class="infopeak-captcha" data-sitekey="YOUR_SITEKEY"></div> inside the form.
2. Verify on your server
When the form is submitted, send the sitekey, your secret and the token to https://captcha.infopeak.io/api/v1/pow/siteverify. The answer tells you whether the token is valid.
Moving from reCAPTCHA, hCaptcha or Turnstile? The full guide at infopeak.io/captcha/developers shows how to switch with minimal changes.
