I'm just working on an integration with the latest v3 Google Captcha API when it became apparent that literally none of this actually works. (Or at least, would never have worked as documented - does anyone have documentation to show how to set this up?)
In all cases, if copying and pasting the code given in the above example (and obviously replacing 'site_key' with your actual key, you will always get ERROR for site owner: Invalid key type
Anyone have any suggestions or a fix for how we actually set this up?
Many thanks for any help,
