Implementing reCAPTCHA V3 - website shows score, Marketo shows { "success": false, "error-codes": [ "invalid-input-response" ] }

Hello,

I watched @SanfordWhiteman 's webinar on implementing Google reCAPTCHA V3 in Marketo and shared it with the web dev team for my client.

I've watched the video a ton of times and passed the codepen below the web dev team

The website is showing success and has a score but it isn't passing to Marketo

Response = { "success": false, "error-codes": [ "invalid-input-response" ] }

Below are screenshots of the web and Marketo

Here's what I did in Marketo

Webhooks created

 Campaign Flow

 And put the secret key as a MyToken

Appreciate any tips or help on how to get the score into Marketo.

Thanks,

Liza
