Answer 1

DialogFlow has a concept called a follow-up intent that you could use in a case like this: You would create a "yes" follow-up to capture if the user wants to proceed, a "no" to cancel, and a "fallback" to explain to the user what is happening and what are acceptable answers. If you are working with Actions on Google, you could also use askForConfirmation which is done completely from within your webhook code. You can choose the most appropriate way depending on how your code is structured.
