Can someone tell me if WDC is required or it can be done in python?? In Tableau, create a Viz with few parameters e.g. Market. User selects a particular Market and This Market is passed to the API as JSON Query. In Response to the JSON Query, API sends another JSON File with Result data for the Selected Market. This Result data has to be presented in the Tableau Viz using JSON as Data Source.

In Tableau send JSON Query and receive JSON Data from API
