The Set Variable action lets you define a value that can be reused anywhere later in your endpoint flow. Variables created with this block are scoped to the current execution only.

​
Name

The Name field defines the variable identifier. This is the key you will use when referencing the value later in the flow. Variable names:
  • Must be unique within the same execution scope
  • Should not contain spaces
  • Are case-sensitive
If another Set Variable block uses the same name later in the flow, the previous value is overridden.

​
Value

The Value field defines what is stored in the variable. This can be:
  • Static text (for example, Hello world)
  • A number (for example, 42)
  • A boolean (true / false)
  • A dynamic reference (for example, {request.body.name})
  • A computed value from previous blocks or input from a query parameter
The value is stored exactly as defined at the moment this block runs.

​
Referencing Variables

Use the following syntax: 
{local.VARIABLE_NAME}

​
Example

If you create:
  • Name: userId
  • Value: {request.body.id}
You can reference it later as: 
{local.userId}

​
Behavior & Scope

  • Variables are available only during the current endpoint execution.
  • Variables do not persist between requests.
  • Variables can be overridden by redefining the same name later in the flow.
The Set Variable block helps keep flows clean, readable, and easier to maintain.
