Is it possible to use Cloudflare Turnstile with serverless f

Yes, Cloudflare Turnstile integrates well with serverless functions. Your ReactJS application sends the Turnstile token to your serverless function, which then validates it using the Cloudflare Turnstile API. This approach is scalable and cost-effective, as serverless functions only execute when needed. Ensure your serverless function has access to the Turnstile secret key via environment variables.
