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

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
