Parse JSON Responses
Extract fields using ArduinoJson.
Responses Are Just Text
A server reply arrives as one long string. To use a value inside it, you first have to pull that value out cleanly.
Why Not Search by Hand
Hunting through text with indexOf is fragile. A real JSON parser understands the structure and gives you fields safely.
