Using ECMAScript with JSON objects

You might want to configure a guard condition for a JSON message. You can use a Function action and ECMAScript, which supports JSON objects.

If you need to extract data or count the number of children in a JSON message you can use the Function action. ECMAScript has built-in support for JSON objects.

If it is not possible to do what you need to do in the message editor, you can use a Function action to process the message payload.

Tag the text (String) node of the incoming message.

Convert it to a JSON object as follows:

var obj = JSON.parse(tags["text"]);

Refer to the data values.
