Update two channels (different API’s) in Thingspeak

Uploading to two different channels in Thingspeak is fairly easy and can be done with the code below.
The code does close connection in between the uploads, perhaps that isnt necessary but I had some trouble getting it to work without closing the connection,not saying it cant be done

void  sendDataToThingspeak(void)
{

// make TCP connections
  WiFiClient client;
  const int httpPort = 80;
  if (!client.connect(thingspeakServer, httpPort)) {
    return;
  }

  String url = "/update?key=";
  url += writeAPIKey;
  url += "&field1=";
  url += String(humidity);//
  url += "&field2=";
  url += String(humiditySetPoint );//
  url += "&field3=";
  url += String(humidifier);
  url += "&field4=";
  url += String(autoMode); //
  url += "&field5=";
  url += String(t);
  url += "\r\n";

  // Send request to the server
  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" +
               "Connection: close\r\n\r\n");
               
  // Second channel            

//-------- Make new connection
 if (!client.connect(thingspeakServer, httpPort)) {
    return;
  }
  url = "/update?key=";
  url += writeAPIKey2;
  url += "&field1=";
  url += String(value1);// 
  url += "&field2=";
  url += String(value2 );// 
  url += "\r\n";
    client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" +
               "Connection: close\r\n\r\n");
 Serial.println("Thingspeak");
}
