Action: parse JSON

Extracts specific data points from a JSON data structure or from a variable of type "Object." This is useful for example when processing the response that is returned in an API call made through the "Send HTTP request" node.

Input

Variable	Type	Description
JSON variable	Object/JSON	The source variable or JSON structure to be parsed.
Output variables	List	A series of defined extractions. Each requires a JSON selector, a name, a type, and an error handling rule.

Defining variables to extract from a JSON payload

Configuration Details

For each output variable defined, the node requires:

• JSON Selector: The path used to identify the location in the document from which to extract the value.
• Name: The name of the variable to be created.
• Type: The data type of the extracted value.
• Error Handling: The logic to follow in the event the selector fails or the data is missing.

Error handling

Each output variable can define what to do in the event of a failed extraction. Options include:

• Fail workflow execution. This terminates the workflow and marks it as an error.
• Proceed with default values. This allows execution of the workflow to continue and populates the output variable with a default value the user provides.
• Log a warning and continue execution. This allows execution of the workflow to continue, logs a warning visible in the execution history, and assigns a null value.

Defining what happens in the event of a parse error

Output

The node outputs individual variables as defined in the "Output variables" section.
