The Variable node lets you save one or more values in memory ($memory) without sending any message to the user. It is useful for preparing data before using it in subsequent nodes.

​
Configuration

Each variable is defined with two fields:
  • Variable: The name under which it will be saved in memory
  • Value: The data to store (can be fixed text, a number, or a reference to another variable)
You can add multiple variables in a single node using the “Add new variable” button.
Variable names must be unique within the same node. If you use a repeated name, you will see a validation error.
Each Variable node allows a maximum of 20 variables. If you need to save more values, distribute them across multiple Variable nodes.

​
Example

If you configure:
VariableValue
fullName{{$user.names}}
channelwhatsapp
greetingHello {{$user.names}}, welcome
The variables will be available as:
  • {{$memory.fullName}}
  • {{$memory.channel}}
  • {{$memory.greeting}}
