retain information by passing through flows in Dialogflow CX

[budy]

Hi, 
I built a chatbot in dialogflow CX with several flows. I want to keep a information (for exemple i'm already client) even if I'm moving from one flow (move) through different flows and back to the flow move... I don't want the bot ask the question again when I've already got the answer... 
With conditions/variables  i guess but I don't know where and what to put on. 

Thanks

You could use session variables and parameter presets to do this. When you collect a piece of information, you could use a parameter preset to save that to a variable. e.g. isClient = TRUE. You can then access that variable later ($session.params.isClient) and use it in a condition.
