Set Node

What it does​

Creates or reshapes an object by assigning fields from expressions, constants, or values from prior node outputs.

Inputs/config​

  • Target key-value assignments.
  • Expression mode per field (literal vs evaluated).
  • Optional overwrite behavior for existing keys.

Outputs/branches​

  • No matched_output.
  • Emits transformed object on default edge.

Example usage snippet​

{
  "id": "n_set",
  "type": "set_node",
  "config": {
    "assignments": {
      "orderId": "{{input.id}}",
      "source": "partner-api"
    }
  }
}

Common pitfalls​

  • Overwriting nested objects unintentionally.
  • Mixing literal and expression syntax inconsistently.
  • Building very large payloads when only a subset is needed.
