Save variables?

Hello
How long a variable is stored.
My idea is that on first access the person will answer alexa’s questions.
later another time she can ask alexa and she responds.
It is possible?

Hi Marcelo,
Yes, the “project” variables in Voiceflow persist for each individual user. They are “global” variables, and will retain values from one session to the next. In regards to your use case, you could store a value in a variable in one session, and have it available when the same user returns in the next session.
