How to Download and Use Instagram4j Jar File

Instagram is one of the most popular social media platforms in the world, with over one billion users. However, if you want to access Instagram’s private API and create your own applications using Java, you may need a library like instagram4j.

In this article, we will explain what instagram4j is, how to download and use its jar file, what features it offers, and what alternatives you can consider. By the end of this article, you will have a better understanding of how to use instagram4j for your own projects.

What is Instagram4j and Why Use It?

Instagram4j is a Java library that provides requests that emulate the Android Instagram app. Most of the official app functionality is supported here. This library has undergone a massive rewrite (instagram4j 1.x.x is not compatible) The rewrite intends to help with maintainability and flexibility throughout time.

Using instagram4j, you can create your own applications that interact with Instagram’s private API. For example, you can post photos and videos, view stories, send direct messages, search for tags and locations, and more. You can also access features that are not available in the public API, such as two factor login, challenges, iterable feeds, serialization, etc.

A jar file is a Java archive file that contains compiled Java classes and other resources. It is used to distribute and run Java applications. To download the instagram4j jar file, you can use gradle or maven as dependency management tools. We will show you how to do that in the next section.

Features of Instagram4j

Instagram4j offers many features that make it a powerful and flexible library for Instagram private API. Here are some of the notable ones:

• Emulates the Android Instagram app: Instagram4j uses OkHttpClient and jackson-databind to send requests that mimic the Android Instagram app. This means that you can access most of the features that are available in the official app.
• Supports most of the official app functionality: Instagram4j supports timeline, story, live, direct messaging, shopping, and more. You can also perform actions such as liking, commenting, following, unfollowing, blocking, reporting, etc.
• Uses OkHttpClient and jackson-databind: OkHttpClient is a HTTP client that supports HTTP/2, SPDY, connection pooling, compression, caching, etc. Jackson-databind is a JSON processor that allows you to read and write JSON data from/to Java objects.
• Supports two factor login, challenges, iterable feeds, serialization, etc.: Instagram4j handles various scenarios that may occur when using Instagram’s private API. For example, it supports two factor login for accounts that have enabled it. It also supports challenges for accounts that need to verify their identity or phone number. It also allows you to iterate over feeds such as user feed or hashtag feed. It also allows you to serialize and deserialize the client object using IGClient.Builder class.

How to Use Instagram4j

To use instagram4j, you need to install the library using gradle or maven. Here are the steps to do that:

Install the Library Using Gradle

Gradle is a build automation tool that helps you manage dependencies and tasks for your Java projects. To install instagram4j using gradle, you need to add the following lines to your build.gradle file:


repositories { mavenCentral() } dependencies { implementation 'com.github.instagram4j:instagram4j:2.0.9' }

Then, you can sync your project and the library will be downloaded and added to your classpath.

Install the Library Using Maven

Maven is another build automation tool that helps you manage dependencies and tasks for your Java projects. To install instagram4j using maven, you need to add the following lines to your pom.xml file:

com.github.instagram4j
instagram4j
2.0.9

Then, you can run mvn install and the library will be downloaded and added to your classpath.

Setup and Login Using Simple, Two Factor, Challenge, or Proxy Methods

After installing the library, you need to setup and login using one of the methods supported by instagram4j. Here are some examples of how to do that:

Simple Login

This is the simplest way to login using instagram4j. You just need to provide your username and password and call the login() method on the IGClient.Builder object. For example:


IGClient client = IGClient.builder() .username("your_username") .password("your_password") .login();

This will return an IGClient object that you can use to send requests and actions to Instagram’s private API.

Two Factor Login

If your account has enabled two factor authentication, you need to provide an additional code to login using instagram4j. You can use the login(Consumer<TwoFactorForm>) method on the IGClient.Builder object and pass a consumer function that handles the two factor form. For example:


IGClient client = IGClient.builder() .username("your_username") .password("your_password") .login(twoFactorForm -> { // get the code from SMS or authenticator app String code = ...; // set the code and submit the form twoFactorForm.setCode(code).submit(); });

This will return an IGClient object that you can use to send requests and actions to Instagram’s private API.

Challenge Login

If your account needs to verify its identity or phone number, you need to handle a challenge to login using instagram4j. You can use the login(Consumer<ChallengeForm>) method on the IGClient.Builder object and pass a consumer function that handles the challenge form. For example:


IGClient client = IGClient.builder() .username("your_username") .password("your_password") .login(challengeForm -> { // choose how to receive the verification code (SMS or email) String choice = ...; // send the choice and get the challenge Challenge challenge = challengeForm.sendChoice(choice); // get the code from SMS or email String code = ...; // set the code and submit the challenge challenge.setCode(code).submit(); });

This will return an IGClient object that you can use to send requests and actions to Instagram’s private API.

Proxy Login

If you want to use a proxy server to login using instagram4j, you need to provide a proxy object to the IGClient.Builder. You can use any proxy implementation that is supported by OkHttpClient, such as java.net.Proxy or okhttp3.Proxy. For example:


// create a proxy object Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy_host", proxy_port)); // pass it to the builder IGClient client = IGClient.builder() .username("your_username") .password("your_password") .proxy(proxy) .login();

This will return an IGClient object that you can use to send requests and actions to Instagram’s private API.

Send Requests and Actions Using InstagramClient Object

Once you have logged in using instagram4j, you can use the IGClient object to send requests and actions to Instagram’s private API. The IGClient object has various methods that allow you to access different features of Instagram. For example:

• actions(): returns an IGClientActions object that allows you to perform actions such as liking, commenting, following, unfollowing, blocking, reporting, etc.
• publish(): returns an IGClientPublish object that allows you to publish photos and videos to your timeline, story, or direct messages.
• discover(): returns an IGClientDiscover object that allows you to discover new content and users based on your interests and preferences.
• live(): returns an IGClientLive object that allows you to create and join live broadcasts on Instagram.
• shopping(): returns an IGClientShopping object that allows you to browse and buy products from Instagram shops and catalogs.
• direct(): returns an IGClientDirect object that allows you to send and receive direct messages with other users.
• user(): returns an IGClientUser object that allows you to access and modify your own profile information and settings.
• search(): returns an IGClientSearch object that allows you to search for users, tags, locations, or places on Instagram.
• feed(): returns an IGClientFeed object that allows you to access various feeds such as user feed, hashtag feed, location feed, etc.
• story(): returns an IGClientStory object that allows you to view and interact with stories from other users or yourself.

To send a request or action using the IGClient, you need to call the appropriate method and pass the required parameters. For example, to like a post with a given media id, you can do:


// get the media id of the post String mediaId = ...; // like the post using IGClientActions client.actions().timeline().like(mediaId).join();

This will send a request to like the post and return a ListenableFuture<StatusResult>. You can use the .join(), .get(), or .thenAccept() methods to get the result or handle it asynchronously. You can also use the .exceptionally(), .handle(), or .whenComplete() methods to handle any exceptions or errors that may occur.

Serialize and Deserialize the Client Using IGClient.Builder Class

A useful feature of instagram4j is that it allows you to serialize and deserialize the client object using the <user](#message) Continue writing the article. IGClient.Builder class. This means that you can save the state of the client and restore it later without logging in again. This can be useful if you want to avoid unnecessary login requests or persist the client across different sessions.

To serialize the client, you need to call the serialize() method on the IGClient object. This will return a byte[] array that contains the serialized data of the client. You can then save this array to a file or a database for later use. For example:


// serialize the client byte[] data = client.serialize(); // save the data to a file Files.write(Paths.get("client.ser"), data);

To deserialize the client, you need to create a IGClient.Builder object and call the deserialize(byte[]) method on it. This will return an IGClient object that contains the deserialized data of the client. You can then use this object to send requests and actions to Instagram’s private API. For example:


// load the data from a file byte[] data = Files.readAllBytes(Paths.get("client.ser")); // deserialize the client IGClient client = IGClient.Builder.deserialize(data);
