Cloud to Device Messaging Azure IoT Hub

Hi @jk123 and welcome to the community!

A few days ago someone asked a similar question, just for another Cloud provider.
Would you like to have a read?
Here:

Receive Data from Google Cloud

The Google pub/sub integration is unidirectional from the Particle device to the Google cloud. You can’t subscribe to a Google pub/sub event on a Particle device. You can, however, call the Particle Cloud API from a Google cloud function or AppEngine instance, and that’s the usual way you communicate back to your Particle device, using the native Particle function, variable, or Particle event subscription.

Keep asking if not clear enough.
Cheers
Gustavo.
