}Base64 JSON Decoding
The JSON data is Base64 encoded. You must decode this into a JSON string and convert that into a multi-hierarchical object.
This example shows the custom variables in the App Studio configurator on the left and a matching portion of the multi-hierarchical object returned from the API.
Here is an example of a partial list of all data sources. The full list can be very large so it is not supplied here.
