Add subscriber to my mailchimp subscriber list - node.js

Question

I am new to backend web development and trying to create subscriber through a sign up page and add them to my Mailchimp through API but I am not been able to create subscriber (subscribers are not adding in my Mailchimp audience list). Below is my code.
const port = 3000;
const https = require('node:https');
const express = require('express');
const app = express();
app.use(express.static("public"));
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({
extended: true
}));
app.get('/', (req, res) => {
res.sendFile(__dirname + "/signup.html")
});
app.post('/', (req, res) => {
const email = req.body.emailId;
const firstName = req.body.firstName;
const lastName = req.body.lastName;
var data = {
members: [{
email_address: email,
status: "Subscribed",
merge_fields: {
FNAME: firstName,
LNAME: lastName
}
}]
};
const jsonData = JSON.stringify(data);
const url = "https://us11.api.mailchimp.com/3.0/lists/"list_id"/";
const options = {
method: "POST",
auth: "dALamyan:apiKey"
};
const request = https.request(url, options, (response) => {
response.on("data", (data) => {
console.log(JSON.parse(data));
});
});
request.write(jsonData);
request.end;
});
app.listen(port, () => {
console.log("app listening on port 3000.");
});

You can try my code below. It's working fine for me.
Change X in the API endpoint, listID and apiKey as per your account settings.
Cheers.
const express = require("express");
const bodyParser = require("body-parser");
const request = require("request");
const https = require("https");
const app = express();
app.use(express.static("public"));
app.use(bodyParser.urlencoded({ extended: true }));
app.get("/", (req, res) => {
res.sendFile(__dirname + "/signup.html");
});
app.post("/", (req, res) => {
const firstName = req.body.firstname;
const lastName = req.body.lastname;
const email = req.body.email;
const data = {
members: [{
email_address: email,
status: "subscribed",
merge_fields: {
FNAME: firstName,
LNAME: lastName
}
}]
};
const jsonData = JSON.stringify(data);
const url = "https://usX.api.mailchimp.com/3.0/lists/" + listID;
const options = {
method: "POST",
auth: "archit:apiKey"
}
const request = https.request(url, options, (response) => {
response.on("data", (data) => {
console.log(JSON.parse(data));
});
});
request.write(jsonData);
request.end();
});
app.listen("3000", (req, res) => {
console.log("Server is running on port 3000.");
});
