Yes, you need to pass a JSON String similar to above when sending in JSON
events.

To use the event builder with mapping type as JSON, you need to specify a
JSON path query (like as you would specify an XPath for XML).
You can find a sample JSON event builder mapping in [1]. You can also find
some examples for JsonPath syntax in [2] and [3].
CEP actually uses the library in [2] to process JsonPath underneath.
