@BulldogLowell Yes, that looks like exactly what I want to do.
I see that the in the Particle Console when you create a product you can then set up webhooks and click a button only to allow the response to be picked up by the device that sent requested the info.
I do like @BulldogLowell 's code though because it does the same thing without the need for paying fees associated with product services once you go over 25 devices. It’s nice that the Product service offers this easy to use a push button to allow only the device that requested the webhook to receive that reply.
Now I have to code this, so it works for me
