Variables

Variables

Flowise allows users to create variables that can be used in nodes. Variables can be Static or Runtime.

Static​

The static variable will be saved with the specified value and retrieved as is.

Runtime​

The variable's value will be obtained from the .env file using process.env.

Override or Set Variables via API​

To override a variable's value, the user must explicitly enable it from the Chatflow Settings -> Security tab:

a

If a variable already exists, the variable value provided in the API will override the existing value.

{
    "question": "hello",
    "overrideConfig": {
        "vars": {
            "var": "some-overridden-value"
        }
    }
}

Using Variables​

Variables can be used by nodes in Flowise. For example, a variable named character is created:

a

Then we can use this variable as $vars.<variable-name> in the Function of the following nodes:

a

Additionally, the user can also use the variable in the text input of any node with the following format:

{{$vars.<variable-name>}}

For example, in the Agent System Message:

a

In the Prompt Template:
