Could anyone refer me to an example on how to route multiple variables from a particle electron/photon to GS ?

I worked through the simple example - no problem
https://www.grovestreams.com/developers/getting_started_particle_webhook.html

However, now I need to publish and webhook multiple floating point variables (like data from a weather station).

My main issue is correctly formatting the publish command and webhook on the particle side so its compatible with GS.

A good example of something similar would be REALLY useful.

Thanks,
