Get Keys

Retrieves all keys from a JSON object.

Common Properties​

  • Name - The custom name of the node.
  • Color - The custom color of the node.
  • Delay Before (sec) - Waits in seconds before executing the node.
  • Delay After (sec) - Waits in seconds after executing node.
  • Continue On Error - Automation will continue regardless of any error. The default value is false.

Inputs​

  • Payload - JSON object from which to retrieve keys.

Options​

This node does not have any options.

Outputs​

  • Keys - Array of strings containing all keys from the JSON object.

How It Works​

The Get Keys node extracts all key names from a JSON object. When executed, the node:

  1. Receives a JSON object through the Payload input
  2. Iterates through all key-value pairs in the object
  3. Collects all key names into an array
  4. Outputs the array of keys through the Keys output

Requirements​

  • Valid JSON object as input

Error Handling​

The node will return specific errors in the following cases:

  • Invalid JSON object in the Payload input

Usage Notes​

  • This node is useful for inspecting JSON object structures
  • Returns only the top-level keys, not nested keys
  • The order of keys in the output array matches the order in the JSON object
  • Works with any valid JSON object structure
  • Useful for data analysis and validation workflows
  • Can be combined with other JSON nodes to build dynamic processing pipelines
  • The output array can be used with array processing nodes
  • If the input object is empty, the node will return an empty array
  • Works with objects containing any type of values including nested objects and arrays
