How to generate different recaptcha API keys for subdomain?

Question

We'd like to have separate reCaptcha API keys for our development and production environments, but the development site is a subdomain of the production site:

www.mysite.com

dev.mysite.com

From the Google docs, it looks like as soon as we add mysite.com to the captcha domain list, it will use the same API key for all subdomains - is it possible to use set up different API keys for a subdomain?

Answer 1

I was not able to get a subdomain separated out to use a different API key, but Google does provide a sandbox Site Key/Secret pair that can be used to test the recaptcha and not clutter up productions analytics. It's set to always return a valid response, but you can easily modify that response within the application as failed for testing. Test recaptcha key & secret can be found at:
