Hi Josh,
Over here we just call them Apps 
For the cloud endpoint you can use something like this to build the url:
"${getApiServerUrl()}/${hubUID}/apps/${app.id}/<PATH>?access_token=${state.accessToken}"
just replace <PATH> with the endpoint you are trying to hit.
For the local enpoint , we are going to add a method for this, but right now you can access it like this:
http://<HUB IP>/apps/api/<APP ID>/<PATH>?access_token=<ACCESS TOKEN>
just replace the <> values with the ones that match your Hub and App
