How to Use hCaptcha

Implementing hCaptcha typically involves adding a few lines of code to your website or application. Here’s a general overview:

1. Sign Up & Get Keys: Create an hCaptcha account on their website to obtain your unique site key and secret key.

3. Implement Server-Side Verification: On your server, verify the token received from the user’s browser after they solve the hCaptcha challenge by sending a request to the hCaptcha API endpoint using your secret key. This confirms the user is human.
4. Configure Settings (Optional): Access your hCaptcha dashboard to customize settings such as challenge difficulty, themes, and other features based on your plan and needs.
