Per Google's documentation:
"reCAPTCHA v3 introduces a new concept: actions. When you specify an action name in each place you execute reCAPTCHA, you enable the following new features:
- A detailed break-down of data for your top ten actions in the admin console
- Adaptive risk analysis based on the context of the action, because abusive behavior can vary.
Importantly, when you verify the reCAPTCHA response, you should verify that the action name is the name you expect."
Associating an action name with each reCAPTCHA implementation location will allow us to have a more granular view of where bots are interacting with our forms/actions and react based on what we see in the reporting. Additionally, Google indicates that reCAPTCHA v3 will perform better with actions specified.
