Use if_else_node for conditional execution based on runtime conditions—handling different page states, optional elements, or branching logic.

​
Condition Syntax

Conditions are Python-like expressions that can reference parameters: 
{
  "condition": "{has_2fa[0]} == 'true'"
}

{
  "condition": "{verification_needed[0]} is not None and {verification_needed[0]} != 'skip'"
}

​
Operators

OperatorExample
Equality{var[0]} == 'value'
Inequality{var[0]} != 'value'
None check{var[0]} is not None
Boolean{var[0]} == 'true'
Logical AND{a[0]} == 'x' and {b[0]} == 'y'
Logical OR{a[0]} == 'x' or {b[0]} == 'y'

Examples

​
Handle Optional 2FA

{
  "type": "if_else_node",
  "condition": "{requires_2fa[0]} == 'true'",
  "if_nodes": [
    {
      "type": "action_node",
      "interaction_action": {
        "input_text": {
          "command": "get_by_label(\"Verification Code\")",
          "input_text": "{auth_code[0]}"
        }
      }
    }
  ],
  "else_nodes": []
}

​
Branch Based on Extracted Value

[
  {
    "type": "action_node",
    "extraction_action": {
      "llm": {
        "extraction_format": { "status": "str" },
        "extraction_instructions": "Extract the order status",
        "output_variable_names": ["status"]
      }
    }
  },
  {
    "type": "if_else_node",
    "condition": "{status[0]} == 'pending'",
    "if_nodes": [
      {
        "type": "action_node",
        "interaction_action": {
          "click_element": {
            "command": "get_by_role(\"button\", name=\"Approve\")"
          }
        }
      }
    ],
    "else_nodes": []
  }
]

​
Nested Conditions

{
  "type": "if_else_node",
  "condition": "{user_type[0]} == 'admin'",
  "if_nodes": [
    {
      "type": "if_else_node",
      "condition": "{access_level[0]} == 'full'",
      "if_nodes": [ ... ],
      "else_nodes": [ ... ]
    }
  ],
  "else_nodes": []
}
else_nodes is optional. If omitted or empty, nothing happens when condition is false.
