If you go to [1] google.com/recaptcha/admin , choose the website you created your API keys for, and click on cog wheel on the right upper corner, You will see recaptcha type and reCaptcha keys, click on that to view keys you have created. It shows you Site key AND secret key
or

Use your web browser to go to Google’s reCAPTCHA site[2]
Click the blue Admin console button on the upper right-hand side of the page

No, I'm not looking for the score, but why the request was considered mid or high risk.

“There are many reasons , these values are subject to change in the future, look at them as thresholds and not check absolute values. reCAPTCHA Enterprise learns by monitoring real traffic on your site. Therefore, scores in a staging environment and within 7 days of implementation might differ from the long-term production scores.”

Finally I would like to ask if you could get the reason codes of the scores as they can provide additional information about how reCAPTCHA Enterprise interpreted these interactions as we can see in [2].

please refer to our FAQ for common issues you might encounter or questions you might

have while using reCAPTCHA Enterprise.[1]
