The Get nodes action extracts the key values from a JSON source that you specify in the Start session action.

You can specify the exact key or a specific path in the Get nodes to extract the keys. You also specify a new key name for the extracted value.

Settings

The following settings are available in this action.

Session name
The session identifier. Enter the session name that you specified in the preceding Start session action. You can enter the session name directly, select the string variable that contains the session name, or select the session variable.
Nodes to extract
Specify the nodes or the node path to extract their value. Click Add nodes and configure the following parameters in the Add node modal:
  • Node key or path: The name of node key or the node path.
  • Value type: The data type of the node. The options include String, Number, Boolean, and DateTime.
    Note: The Get node action extracts the date and time only when the JSON sample follows these ISO8601 formats:
    • DateTimeFormatter.ISO_ZONED_DATE_TIME. For example: 2023-08-19T14:30:00+05:30[Asia/Kolkata]
    • DateTimeFormatter.ISO_OFFSET_DATE_TIME. For example: 2023-08-19T14:30:00+05:30
    • DateTimeFormatter.ISO_INSTANT. For example: 2023-08-19T14:30:00Z
  • Rename key: A new key name for the extracted node key. The action saves the extracted value with this new key name in the output variable. This field enables extraction of deeply nested nodes.
The Get nodes action supports extraction multiple node values. Click Add node to define the parameters for each target node.
Assign output to a variable
Specify multiple variables to save specific node values or a dictionary variable to save all the extracted values in a single dictionary variable.
  • Multiple variables: Select Multiple variables > Add variable mapping and follow the prompts on the Variable mapping modal to enter a specific key and choose a corresponding variable in which the extracted node values must be saved.
  • Dictionary: Select Dictionary, and choose an existing dictionary variable or use Create variable option to create a dictionary variable.

Format for Node key or path setting

This section describes the format to specify node keys and node key paths in the Node key or path setting. You can use dot notation to extract nested nodes and nodes with arrays.

For this JSON source:

{
  "phone": "123456789",
  "company": 
	{
    "name": "XYZ Corp",
    "City": "ABC",
    "Country": "DEF",
	"orders": [
    {
      "orderId": "A-101",
      "item": "Laptop Stand",
      "price": 45.00
    },
    {
      "orderId": "A-102",
      "item": "Wireless Mouse",
      "price": 25.50
    }
    ]
  }
}
Specify the following:
  • phone to extract the phone number.
