google dialogflow conditional response does not work

Question

I have two Entity types (@name and @ surname) . If the customer can enter these two parameters I will send the flow to another page. is it possible can I do this with conditional response?

I wrote a simple code like below but It does not work. I get "true" as output even if I don't enter my surname

if ($session.params.name! = " ") OR ($session.params.surname != " ")
      'true'
    else
      'false'
    endif

Thank you.

Are you trying to write the code using Webhook or in the Customize expression field of Dialogflow CX UI? — Sandeep Mohanty, Dec 06 '21 at 07:04

Yes, you can accomplish this by creating a route with a condition.

A route may include an intent and/or a condition. The CX UI includes this feature as well as boolean logic to help achieve your desired outcome. Example condition using user defined session parameters

Then you can define the fulfillment and transition as needed.

I think if you are not entering anything, the parameter will resolve as 'null', hence, also not " ". I would do it this way.

if $session.params.name! = null OR $session.params.surname != null OR ($session.params.name! = " ") OR ($session.params.surname != " ")
      'true'
    else
      'false'
    endif
