Can I make Dialogflow intents require atleast one of the trained entities?

问题

I know how to make intents require any parameter value, after which the intent will force to get the value; but is it possible to make it force to get atleast one of the given entity parameters ?

回答1:

You could enable webhook fulfillment for that intent and if no entities were provided, reprompt the user for at least one of a list of entities.
