Please provide the screenshots of the fields and the webhook configuration.
Thank you Greg for asking.

Found the fields. thanks
Mark your answer as the right one, for further reference
Thanks to Sanford Whiteman, the integration with reCaptcha is finally working!
The issue with my code was a capital letter in the JS file. After getting that fixed Marketo was able to properly get a response from Google in the webhook.
The issue was on this line:
The "last" had a capital "L" in front so it never sent the response to Marketo.
Without Sanford's help I'd never find out I think
Thank you very much again Sanford and if anyone need help with this integration I can give a bit more detail.
