Static variables are flow-agent only. They are set at the node level with fixed or templated values and are available to that node and its successors.

​
Characteristics

  • Scope: Node-level; visible to successor nodes
  • Where to define: In the node’s configuration
  • Value types: string, number, boolean, array, object
  • Templates: Values can use {{variable_name}} to reference other variables
  • Sync: Stored in the variable store so availability is tracked correctly

​
