AWS Web Application Firewall customers can now use the AWS WAF Captcha JavaScript API for enhanced control over the Captcha workflows. AWS WAF Captcha helps block unwanted bot traffic by requiring users to successfully solve visual or audio problems before their web requests are allowed. Until today, AWS WAF Captcha redirected customers to a different page for solving the Captcha problem. With this release, developers can improve the Captcha customer experience by embedding Captcha problems in their existing webpages, including Single Page applications (SPAs).
