▎Step-by-Step Analytics Setup

▎1. Track Total Users

Monitor the total number of unique users interacting with your bot.

Command: /start

let totalUsers = Bot.getProperty("totalUsers") || 0;
if (!User.getProperty("tracked")) {
   totalUsers += 1;
   Bot.setProperty("totalUsers", totalUsers, "integer");
   User.setProperty("tracked", true, "boolean");
}
Bot.sendMessage("🎉 Welcome! You’re user number: " + totalUsers);

Command to Check Total Users: /stats

let totalUsers = Bot.getProperty("totalUsers") || 0;
Bot.sendMessage("📊 Total Users: " + totalUsers);

---

▎2. Track Command Usage

Identify which commands are most popular among users.

Add to All Commands to Log Usage:

let commandLogs = Bot.getProperty("commandLogs") || {};
commandLogs[command_name] = (commandLogs[command_name] || 0) + 1;
Bot.setProperty("commandLogs", commandLogs, "json");

Command to View Command Usage Stats: /commandstats

let commandLogs = Bot.getProperty("commandLogs") || {};
let stats = "📋 Command Usage Stats:\n";

for (let cmd in commandLogs) {
   stats += cmd + ": " + commandLogs[cmd] + " uses\n";
}

Bot.sendMessage(stats);

---

▎3. Monitor User Activity

Keep track of when users were last active to identify those who may need re-engagement.

Add to All User-Facing Commands:

User.setProperty("lastActive", new Date(), "string");

Command to View Inactive Users: /inactiveusers

let allUsers = Bot.getAllUsers();
let inactiveUsers = [];
let threshold = 7; // Days of inactivity

for (let user of allUsers) {
   let lastActive = new Date(User.getProperty("lastActive", user.telegramid));
   let now = new Date();
   let daysInactive = (now - lastActive) / (1000 * 60 * 60 * 24); // Convert milliseconds to days
   if (daysInactive > threshold) {
      inactiveUsers.push(user.telegramid);
   }
}

Bot.sendMessage("👥 Inactive Users (> " + threshold + " days): " + inactiveUsers.length);

---

▎4. Track User Engagement Metrics

Implement a points system to encourage user participation.

Command: /addpoints

let points = Libs.ResourcesLib.userRes("points");
if (points.value() == 0) {
   let engagedUsers = Bot.getProperty("engagedUsers") || 0;
   engagedUsers += 1;
   Bot.setProperty("engagedUsers", engagedUsers, "integer");
}

points.add(10); // Add 10 points
Bot.sendMessage("✅ You earned 10 points! Total: " + points.value());

Command to Check Engaged Users: /engagementstats

let engagedUsers = Bot.getProperty("engagedUsers") || 0;
Bot.sendMessage("📊 Engaged Users (earned points): " + engagedUsers);

---

▎5. Track Daily User Activity

Keep a record of daily active users to gauge engagement levels.

Command: /trackdaily

let today = new Date().toISOString().slice(0, 10); // Get today's date in YYYY-MM-DD format

let dailyStats = Bot.getProperty("dailyStats") || {};

if (!dailyStats[today]) {
   dailyStats[today] = 0;
}

if (!User.getProperty("countedToday")) {
   dailyStats[today] += 1;
   Bot.setProperty("dailyStats", dailyStats, "json");
   User.setProperty("countedToday", true, "boolean");
}

Bot.sendMessage("📆 Thanks for being active today!");

Command to View Daily Stats: /dailystats

let dailyStats = Bot.getProperty("dailyStats") || {};
let stats = "📊 Daily Active Users:\n";

for (let date in dailyStats) {
   stats += date + ": " + dailyStats[date] + " users\n";
}

Bot.sendMessage(stats);

---

▎6. Export Analytics Data

Export user analytics or stats to external storage like Google Sheets for detailed analysis.

Command: /exportstats

let stats = Bot.getProperty("commandLogs") || {};
let rows = [];

for (let cmd in stats) {
   rows.push([cmd, stats[cmd]]);
}

Libs.GoogleTableSync.write({
   sheetName: "CommandStats",
   range: "A1:B" + rows.length,
   values: rows,
   success: "/exportSuccess",
   error: "/exportError"
});

Success Command: /exportSuccess

API making series start kru???

Ohkk we'll soon start a 30 day api making series in php

Day 1: Introduction to PHP and APIs

1. Basics of PHP:

PHP, which stands for Hypertext Preprocessor, is a powerful server-side scripting language designed for creating dynamic websites and web applications. With PHP, code is executed on the server, generating output that is sent to the browser as standard HTML.

Key Syntax in PHP:

• Begin a PHP script with <?php and conclude with ?>.

• Variables in PHP are prefixed with a dollar sign ($). For instance: $name = "Swastik";

• To display output, you can use echo or print. Example: echo "Hello, World!";

• Ensure each statement ends with a semicolon (;).

Example Code:

<?php
$name = "Swastik";
echo "Welcome to the 30-day PHP API session, $name!";
?>

---

2. Understanding APIs:

An API, or Application Programming Interface, serves as a bridge that enables different software applications to communicate seamlessly with one another.

Example: A weather application utilizes an API to retrieve data from a weather service, allowing users to access real-time information.

---

3. Types of APIs:

• REST APIs: Utilize standard HTTP methods (GET, POST, PUT, DELETE) for communication, making them widely adopted due to their simplicity and efficiency.

 
• SOAP APIs: Rely on XML for communication. While less common today, they are still used in certain enterprise environments.

• GraphQL APIs: Offer a flexible approach by allowing clients to request precisely the data they need, reducing over-fetching and under-fetching issues.

---

4. Example of an API Workflow:

1. A client (such as a browser or mobile app) sends a request to the server.

2. The server processes this request and returns a response in formats such as JSON or XML.

---

Task for Day 1:

1. Write a simple PHP script that outputs your name.

2. Conduct research and document the differences between REST APIs and SOAP APIs.

Looking Ahead: Tomorrow, we will explore the fundamentals of REST APIs! Get ready for an exciting journey into the world of web development!

Day 2: REST API Basics

1. What is REST?

REST means Representational State Transfer.

It is a way to design applications that communicate over the internet. REST uses simple HTTP methods to send and receive information.

REST APIs do not keep any information about previous requests. This means every time you ask for something, you need to include all the details needed to process your request.

2. REST API Methods:

• GET: Use this to get data from the server (like getting user details).

 
• POST: Use this to send new data to the server (like creating a new user).

 
• PUT: Use this to change existing data on the server (like updating user information).

 
• DELETE: Use this to remove data from the server (like deleting a user).

3. HTTP Status Codes:

• 200 OK: Your request was successful.

 
• 201 Created: A new item was successfully created.

 
• 400 Bad Request: There was something wrong with your request.

 
• 404 Not Found: The item you asked for could not be found.

 
• 500 Internal Server Error: The server had an error while processing your request.

4. Request and Response Structure:

Request: When you make a request, it usually includes:

• Method (GET, POST, etc.)

• URL (the address you are trying to reach)

• Headers (extra information, optional)

• Body (the data you send, for POST/PUT requests)

Response: When the server replies, it usually includes:

• Status Code (like 200 or 404)

• Headers (extra information, optional)

• Body (usually in JSON or XML format)

5. Creating Your First REST API Endpoint:

Make a simple PHP file that sends back some data in JSON format using the GET method.

Example Code:

<?php
header('Content-Type: application/json');
$response = array("message" => "Hello, World! This is your first API endpoint.");
echo json_encode($response);
?>

This code sets the response type to JSON and sends back a message in JSON format.

Task for Day 2:

Create a simple PHP script that returns a JSON response when you access it.

Test your script by opening it in your web browser or using Postman.

Tomorrow, we will learn how to create more advanced and interactive API endpoints!

Day 3: Building Your First API Endpoint

Welcome to Day 3! Today, we’re excited to guide you through the process of creating a fully functional REST API endpoint that will accept requests and return meaningful data.

---

▎1. Understanding API Endpoint Structure

An API endpoint is essentially a URL through which your API can be accessed. For example:
http://yourdomain.com/api/endpoint.php

In this session, we’ll construct an API that processes GET requests and responds with user data.

---

▎2. PHP Code for Your API

Let’s create an API that delivers user information in a structured format.

<?php
// Set the response type to JSON
header('Content-Type: application/json');

// Simulate user data (this can be replaced with a database connection later)
$users = [
    ["id" => 1, "name" => "Swastik", "email" => "swastik@example.com"],
    ["id" => 2, "name" => "John", "email" => "john@example.com"],
    ["id" => 3, "name" => "Jane", "email" => "jane@example.com"]
];

// Check if a 'user_id' parameter is provided in the URL
if (isset($_GET['user_id'])) {
    $userId = intval($_GET['user_id']);
    $user = array_filter($users, fn($u) => $u['id'] === $userId);
    
    if (!empty($user)) {
        echo json_encode(array_values($user)[0]); // Return the user data
    } else {
        echo json_encode(["error" => "User not found"]); // Return an error message
    }
} else {
    // If no 'user_id' is specified, return all users
    echo json_encode($users);
}
?>

---

▎3. How to Test Your API

Follow these simple steps to test your newly created API:

1. Save the file as api.php in your server directory.

2. Access the API using your web browser or Postman:

   • To retrieve all users: 
     http://yourdomain.com/api.php

   • To retrieve a specific user: 
     http://yourdomain.com/api.php?user_id=2

---

▎4. Key Concepts Introduced

• Query Parameters: Information sent through the URL (e.g., user_id=2).

• JSON Encoding: Transforming PHP arrays into JSON format using json_encode().

• Condition Handling: Implementing checks for specific parameters in requests.

---

▎Task for Day 3:

1. Implement the API on your local server.

2. Test the functionality with and without the user_id parameter.

3. Enhance the script by adding more fields to the user data (e.g., age, city).

Tomorrow, we’ll take a deeper dive into handling POST requests, expanding our API's capabilities! Happy coding!

Day 4: Handling POST Requests in Your API

Today, we’ll learn to handle POST requests to accept and process client data, used for creating new records.

1. GET vs. POST

•   GET: Sends data via URL (query parameters). Used for fetching data.
•   POST: Sends data in request body. Used for creating/submitting data securely.

2. Creating a POST API Endpoint

Let’s create an API to add a new user via a POST request.
PHP Code:

<?php
header('Content-Type: application/json');
$postData = file_get_contents("php://input");
$data = json_decode($postData, true);
if (isset($data['name']) && isset($data['email'])) {
    $response = [
        "status" => "success",
        "message" => "User added successfully!",
        "user" => [
            "name" => $data['name'],
            "email" => $data['email']
        ]
    ];
} else {
    $response = [
        "status" => "error",
        "message" => "Invalid input. 'name' and 'email' are required."
    ];
}
echo json_encode($response);
?>

3. Testing the POST API

Save as post_api.php.
Use Postman or a similar tool to test:
•   URL: http://yourdomain.com/post_api.php
•   Method: POST
•   Body (JSON):

    { "name": "Swastik", "email": "swastik@example.com" }
    

Expected Response:
•   Success:

{ "status": "success", "message": "User added successfully!", "user": { "name": "Swastik", "email": "swastik@example.com" } }

•   Error:

{ "status": "error", "message": "Invalid input. 'name' and 'email' are required." }

4. Key Concepts Introduced

•   file_get_contents("php://input"): Reads raw POST data.
•   json_decode(): Converts JSON to PHP array.
•   Validation: Ensures required data is present.

Task for Day 4:

•   Create this API.
•   Test with valid and invalid JSON inputs.
•   Modify the API to accept an additional field.

Tomorrow, we’ll work with databases to store data!
