Force users to a yes/no question

Hey, is there a way for me to force a user to answer only with yes/no question?

I tried using fallback but sometimes if the user input a valid intent, the fallback doesn’t trigger, instead, it changes the conversation acoording to that intent. I dont want this to happen but the bot to utter a message like “Please answer with a yes or no”

You need to use a form. Check the sections from_text and validating form input.

I’ll try it, thanks!

Is there any way to activate the form inside an action?

You can do it at the end of an action with the event followupaction.
