Create a reCAPTCHA connector
Google reCAPTCHA (https://www.google.com/recaptcha) protects from bots spamming or brute forcing sites by repeatedly submitting forms.
It would be useful to able to use reCAPTCHA on forms that result in a logic app starting. However reCAPTCHA requires a server side verification call making it difficult to use in a serverless infrastructure.
reCAPTCHA works by making the user perform one or more simple tasks then verifying that the action was human, rather than automated. The client side widget sends the data for the interaction to Google's servers which responde with a "reCAPTCHA response" this response is submitted with the client side form and validated on the serverside by making a second call to Google.
A connector that validated the response code would allow the use of reCAPTCHA by passing the response code to the logic app trigger and validating it in the logic app by performing the verification call.
