Here are the 8 official examples of ArduinoJson. They are available in the "Examples" menu of the Arduino IDE.
This example shows how to generate a JSON document with the ArduinoJson library.
JSON HTTP Client
This example shows how to parse a JSON document in an HTTP response. It uses the Ethernet library, but can be easily adapted for Wifi.
JSON UDP Beacon
