Folks often get confused with the use of DEVICE_ID in the API. It's a unique property that is visible nowhere on the UI to refer to a device apart from the UUID. Having a definition about DEVICE_ID on the resources page where folks are using it might prove to be helpful.

For example, at the top of this page https://www.balena.io/docs/reference/api/resources/device/ we can add a definition for DEVICE_ID to mention what it is for folks to refer before executing any queries.
