This tool is targeted at a technical audience and its purpose is to interact with a Rest API. The screen comprises two main panels: the list of methods on the left-hand side and the method details. When the user selects a method from the list, the right-hand side panel displays info related to the selected item. It shows a short description of what the method does and fields that allow the user to make a request to the API using that method.
The interface was developed in XAML.
