# Set Variable

The *Set Variable* action node allows you to create/set variables in a session in order to [use them at a later point ](/flow/untitled-1.md)in the workflow again. You can set multiple variables using the same *Set Variable* node.

These variables will only be available for the duration of the session.

{% hint style="info" %}
**Note:** *Variable Name* cannot be in a variable format (i.e., cannot be \[\[var]]).
