3. Prerequisites

Obtain an API key by purchasing it from Buy Udemy API Key. The API key is valid for 30 days.

PHP Integration Using cURL

Step 1: Initialize a cURL Session

$apiKey = 'apiKey';

$url = "https://krishnaapps.com/api/udemy/courses/{$apiKey}";

$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch); if(curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
} else {
    $courses = json_decode($response, true);
    print_r($courses); // Display the course data
} 

curl_close($ch);

Explanation:

Initializes a cURL session.
Sets the URL with the API key.
Executes the cURL session and retrieves the response.
Closes the cURL session.

Endpoint: Get Download Links

URL: https://krishnaapps.com/api/udemy/download/{id}/{api_key}
Method: GET
Description: Retrieves download links for course files, including the file size and download link.

Prerequisites

API Key: Users must have a valid API key to access the endpoint.

PHP Integration Using cURL

Step 1: Initialize a cURL Session

$apiKey = 'apiKey';

$courseId = 'courseId';
$url = "https://krishnaapps.com/api/download/{$courseId}/{$apiKey}";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if(curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
} else {
    $files = json_decode($response, true);
    foreach ($files as $file) {
        echo "Size: " . $file['size'] . "\n";
        echo "Download Link: " . $file['download_link'] . "\n";
    }
}

curl_close($ch);

Explanation:

Initialize cURL: Initialize a cURL session with the endpoint URL.
Execute cURL: Executes the cURL request and retrieves the response.
Process Response: Decodes the JSON response and outputs the file details.

Java Integration Using Retrofit

Step 1: Add Retrofit Dependency

Add the following dependencies to your build.gradle file:

implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation 'com.squareup.retrofit2:converter-gson:2.9.0'

Step 2: Create the API Interface

Create an interface to define the API endpoints:

import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.Path;
public interface KrishnaAppsApi {
    @GET("udemy/courses/{api_key}")
Call<List<Course>> getCourses(@Path("api_key") String apiKey); }

Step 3: Define the Data Model

Create a class to model the course data:

public class Course {

private String title;
private String slug;
private String description;
private String objectives;
private String prerequisites;
private String targetAudiences;
private String shortDescription;
private String image;
private String categoryId;
private String duration;
private String lectures;
private String views;
private String tags;
private String authorName;
private String authorImage;
private String authorUrl;
private boolean featured;
private String createdAt;
private String updatedAt;

// Getters and Setters
}

Step 4: Initialize Retrofit and Make a Request

Initialize Retrofit and call the API to fetch the courses:

import retrofit2.Retrofit;

import retrofit2.converter.gson.GsonConverterFactory;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;

import java.util.List;

public class Main {
    public static void main(String[] args) {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("https://krishnaapps.com/api/")
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        KrishnaAppsApi api = retrofit.create(KrishnaAppsApi.class);

        Call<List<Course>> call = api.getCourses("apiKey");
        call.enqueue(new Callback<List<Course>>() {
            @Override
            public void onResponse(Call<List<Course>> call, Response<List<Course>> response) {
                if (response.isSuccessful() && response.body() != null) {
                    List<Course> courses = response.body();
                    courses.forEach(course -> {
                        System.out.println(course.getTitle());
                        // Print other course details as needed
                    });
                } else {
                    System.out.println("Request failed: " + response.code());
                }
            }

            @Override
            public void onFailure(Call<List<Course>> call, Throwable t) {
                t.printStackTrace();
            }
        });
    }
}

Explanation:

Initializes Retrofit with the base URL and Gson converter.
Creates an instance of the API interface.
Makes an asynchronous request to fetch the courses.
Processes and displays the course data upon successful response.
