key

The value used to identify a detector instance. When a device or system sends input, a new detector instance with a unique key value is created. ITE can continue to route input to its corresponding detector instance based on this identifying information. This parameter uses a JSON-path expression to select the attribute-value pair in the message payload that is used for identification. To route the message to the correct detector instance, the device must send a message payload that contains the same attribute-value.
