Greetings all, first I have not played with the API interface, I know of companies using it to interface with their service console. Here is some reading materials that may help you out.
Enable Wyse Management Suite API
Wyse Management Suite server uses a proprietary API to serve requests generated from the user interface components. User Interface created with java scripts which uses a rest like API call to get required data in JSON format. The JSON format is request-specific. You can retrieve the device details or perform actions from the Wyse Management Suite server and integrate the server with your custom client such as service now.
