(C#) JSON Estimote DataDemonstrates accessing some data from an Estimote REST API response. The Estimate REST API responds with a JSON array (i.e. something beginning with "[" and ending with "]"). To parse, this must be made into a JSON object by prepending "{"*":" and appending "}". This example uses the following JSON object:
{"*":[{
