JSON Estimote Data

See more JSON Examples

Demonstrates 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:

{"*":[{
