Several values in same Webhook

Hi

I wonder if it is possible to send several values within same webhook?

In documentation there is a example of Librato webhook

https://docs.particle.io/guide/tools-and-features/webhooks/#an-example-librato-webhook

There is part where value is send

{
"name": "{{SPARK_EVENT_NAME}}",
"value": "{{SPARK_EVENT_VALUE}}",
"source": "{{SPARK_CORE_ID}}"
}

Is it possible to send two values and if so, how can i do that?
