The base URL is where KMFDDM is running and the API key is what you gave to the `-api` switch when you started KMFDDM. The shell scripts are simple `curl` wrapprs that access KMFDDM's REST-ish API and need to know where it is running and how to authenticate.

ID is the enrollment ID of the MDM client. Often this will be the UDID of the device. For example in macOS this is the same as the hardware UUID in System Preferences.

## Basic setup

Awesome, you got things running! Now we'll setup a very basic DDM environment to play with. This is written as a sort of story to follow along with yourself. Hopefully it'll help to get you started and explore some of the DDM concepts.

### Our first "enrollment"

As noted in the [README](../README.md) sets don't really do anything until they are associated with enrollment IDs. But once we do that some of the fun will start to happen so I'll try and walk us through it.
As noted in the [README](../README.md) sets don't really do anything until they are associated with enrollment IDs. But once we do that some of the fun will start to happen so I'll try and walk us through it.

When we say "enrollment" here it's not quite like an MDM enrollment. Here I'm specifically talking about associating a NanoMDM enrollment ID to the "default" set that we just created, above. Of course, once this happens, as we'll see, we'll "turn on" DDM for the enrollment which acts kinda sorta like an "enrollment" *for the DDM protocol* so it can get a little confusing. Overall when referring to "enrollments" throughout this document we're almost certainly talking about NanoMDM enrollment IDs.

So, let's assign my enrollment ID (`2FF3196C-CACE-4AFE-9918-01C38160006F`) to the default set and see what happens:

```sh
$ ./tools/api-enrollment-sets-put.sh 2FF3196C-CACE-4AFE-9918-01C38160006F default

This helper script queries the same endpoint that an enrollment does when it talks the DDM protocol (note the `ddm-*` prefix of the script). By using the same endpoint we can see exactly what a response *for a given enrollment ID* might look like.

Also the `DeclarationsToken` matches for both it and the tokens endpoint. Looks good. Let's make sure the declaration that the client sees also matches:
