how to use multiple variables on the URL of your pushingbox service?

I mean both of them, receiving the UID as an array then sending it to the google sheet

I do not know what you mean by "i cant do the merge", please explain. Which code do you need, the Nodemcu lua code that generates the data or the google script that receives the data and adds it to the spreadsheet or both?

i am making the same project but i cant do the merge could you send your code it may help

Your steps were precise and to the point.

#include

const char* ssid = "xxxxx";
const char* password = "xxxxx"; //replace with your own password
const char* host = "api.pushingbox.com";

const int trigPin = 5;
const int echoPin = 4;
//height of the water tank in centimeter
const int height_tank=25;

//Pin Number of The Motor Relay
int led=0;

// defines variables
int distance;
int duration;

void setup() {
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
pinMode(led,OUTPUT);//Set the Motor Relay Pin as an OUTPUT
Serial.begin(9600); // Starts the serial communication

// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
int ping(){
// Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);
// Calculating the distance
distance= duration*0.034/2;
// Prints the distance on the Serial Monitor
return distance;
}

void loop() {
distance=ping();
int division_lenght=height_tank/5;
int level=distance/division_lenght;
level=5-level;
Serial.println(level);
Serial.println(distance);
if(level==1){
digitalWrite(led,HIGH);
Serial.println(" On");
}else if(level==2){
digitalWrite(led,HIGH);
Serial.println(" On");
}else if(level==3){
digitalWrite(led,HIGH);
Serial.println("On");
}else if(level==4){
digitalWrite(led,HIGH);
Serial.println("On");
}
else{
digitalWrite(led,LOW);
Serial.println("OFF");
}
delay(1000);
Serial.print("connecting to ");
Serial.println(host);

// Use WiFiClient class to create TCP connections
WiFiClient client;
const int httpPort = 80;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}

// We now create a URI for the request
String url = "/pushingbox?";
url += "devid=";
url += "v57D03554AC78F92";
url += "&distance="+String(distance);

Serial.print("Requesting URL: ");
Serial.println(url);

// This will send the request to the server
client.print(String("GET ") + url + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Connection: close\r\n\r\n");
unsigned long timeout = millis();
while (client.available() == 0) {
if (millis() - timeout > 5000) {
Serial.println(">>> Client Timeout !");
client.stop();
return;
}
}

// Read all the lines of the reply from server and print them to Serial
while(client.available()){
String line = client.readStringUntil('\r');
Serial.print(line);
Serial.print("Data Sent!");
}

Serial.println();
Serial.println("closing connection");
