Many Client Site / On Site features can be enabled or disabled via the API. One example is the family of Patrol features. 

Every feature has a code, which is a first letter upper-cased set of concatenated words, like "ShiftAppClockInFeature".

Viewing a Client Site's Features

A client site's list of features are a 1:many array, which can be included in its fetch payload by leveraging our Relation Lists feature:

[GET] /clients/687?include=features

...
"features": [
            {
                "code": "PatrolBrowserReportFeature",
                "name": "On-Site License",
                "description": "Create reports from the browser without the need of a mobile device.",
                "active": true,
                "configurationUri": "",
                "group": "PREMIUM"
            },
            {
                "code": "ShiftAppClockInFeature",
                "name": "Allow clock-in via SHIFT app.",
                "description": "Allow employees to clock-in through the SHIFT app.",
                "active": true,
                "configurationUri": "",
                "group": "PREMIUM"
            },
            {
                "code": "GuardAppSignOutOnlyFeature",
                "name": "Allow users on Guard Tour App to sign-out only",
                "description": "Allow a user on the Guard Tour App to sign out but stay clocked-in. (Android device only version 5.12.14 and up)",
                "active": true,
                "configurationUri": "",
                "group": "PREMIUM"
            },
            {
                "code": "MessageBoardFeature",
                "name": "Message Board Feature",
                "description": "Publish site wide messages for your employees or clients",
                "active": true,
                "configurationUri": "",
                "group": "PREMIUM"
            },
etc.
