How to connect Arduino Uno WiFi to ThingSpeak

#include <Wire.h>

#include <UnoWiFiDevEd.h>

#define CONNECTOR     "rest"
#define SERVER_ADDR   "api.thingspeak.com"
#define APIKEY_THINGSPEAK  "****************" //Insert your API Key

void setup() {
  Ciao.begin();
}

void loop() {
  DHT dht;
  dht.setup(2);

  String uri = "/update?api_key=";
  uri += APIKEY_THINGSPEAK;

  uri += String(dht.getTemperature());

  Ciao.println("Sending data on ThingSpeak Channel");

  if (!data.isEmpty()){
