Installation

You can install this by using npm:

npm install instagram-private-api

Most of us are fighting with time, please support to give me more time to do more awesome features!

What is this?

Since I had lot of trouble with the official API (sandbox etc.) I decided to make a Node.JS api wrapper and to provide the code to others. It is an OOP api, and has a small coverage ... I DO NOT USE THIS FOR SPAM, hope you will not either.

What can you do with this API wrapper?

Pretty much anything that the Instagram PRIVATE API allows, except for some endpoints that you need to implement by yourself or made a pull request to repository.

Features:

You can easily ask for any private endpoint with the Request and WebRequest classes
Session and device management
Follow / unfollow
Upload / delete media (photos)
Like anything you like :P
Search & Iterate for Location, Users, Hashtags
Edit account profile
Resolve challenges (Captcha, Phone verification, Email verification)
Access media from many sources profile / location / hashtag
Access feeds for timeline or discovery
Create and manage new accounts
Send direct messages or list direct messages in inbox
Much more ...

How to use this (quick follow example)?

You need to obtain a session to access endpoints with the Session class:

var Client = require('instagram-private-api').V1;
var device = new Client.Device('someuser');
var storage = new Client.CookieFileStorage(__dirname + './cookies/someuser.json');

// And go for login
Client.Session.create(device, storage, 'someuser', 'somepassword')
	.then(function(session) {
   		// Now you have a session, we can follow / unfollow, anything...
		// And we want to follow Instagram official profile
		return [session, Client.Account.searchForUser(session, 'instagram')]   
	})
	.spread(function(session, account) {
		return Client.Relationship.create(session, account.id);
	})
	.then(function(relationship) {
		console.log(relationship.params)
		// {followedBy: ... , following: ... }
		// Yey, you just followed @instagram
	})

Request & WebRequest Classes

Nice! So you mentioned that we can hit any endpoint?

That is true. Every request going to Instagram is actually performed through the Request & WebRequest classes. For the private endpoints used by Android or iPhone, you can simply use the Request class, which will lead to host i.instagram.com, using the private API. For requests to www.instagram.com (web app), you can use the WebRequest class. WebRequest is a child of Request;

Here is an example (how likes are actually implemented):

return new Request(session)
	.setMethod('POST')
	.setResource('like', {id: mediaId})
	.generateUUID()
	.setData({
		media_id: mediaId,
		src: "profile"
	})
	.signPayload()
	.send()
	.then(function(data) {
		return new Like(session, {});
	})

Let make this clearer and explain it little bit more in detail:

The Request constructor accepts, as its first and only argument a class which should be an instanceof Session class. Session class is the glue between Device and CookieStorage. So if you create a session, you can easily hit any endpoint without worrying about authentication or cookies management.

.setResource(resource:string, params:Object)

is the method to setup the URL, which can be also interpreted as

.setUrl(url:string)

but the setResource method has a predefined list of endpoints, so you don't need to construct the URL by yourself.

.generateUUID()

will generate a Device UUID, which is what every device does, but it's probably not required. Also available on Device.prototype as property id

.setData(params:Object, override:boolean)

will set data you want to send to the Instagram endpoint. With the Request class you can set the body format of the request with method

.setBodyType(type:string)

choices used by instagram are json, form, body, formData (default).

.signPayload()

some endpoints require a signed payload. Under the hood the Instagram apps actually have C++ libraries that are compiled into machine code. This means it is not really easy to see the source of these libraries. This is a great way to not let developers see what is going on. And there is a library called libstrings.so, that has methods to generate signatures for the JSON payload you want to send to Instagram. Funny thing about that is, you need ARM based processor to use these libraries, so you can sign requests but only on ARM based processors.

This is actually gives us 2 choices. One is to start a (virtual) machine with such a processor and build some kind of bridge to communicate. The second is to find out how libstrings.so is working and apply the same behavior in node (which would of course be better).

More about this interesting technique and how to extract keys and also a great source of learning is here: MKHDZNFQ Blog

Luckily for us, we know and we are able to analyze libstrings.so and thus we have a clean implementation of signatures for Instagram.

Signatures are not required for all endpoints, but for all sensitive ones (likes / follow / directs / login), you will receive a 400 Bad Request error, without signature.

Example of JSON payload to sign-in:

65eeaed09d7729f7aea06249c9fa33abd8a65a2a6514658f515346170b27c75b.{"_csrftoken":"missing","device_id":"android-85ee13e5ce740e2d","_uuid":"3c0755b3-a510-4a8e-8674-feb7219c2159","username":"xxxxxxxxxx","password":"xxxxxxxxx","login_attempt_count":0}

The first is the hash (signature), followed by dot and then the JSON payload. The hash is actually created by HMAC encryption, in combination with an encryption key called the private key.

.send(options:Object)

any other options you want to apply to request should be passed as the first argument to the .send method;

.then is just promise library. Must be called after .send. We are using Bluebird library which is a really nice way to work with promises.

The Request and Webrequest classes are built on top of the Request.js library. The Webrequest library can actually use same session. No need to create a new one.

If you need to sniff traffic to see what your phone is doing and see the available endpoints I strongly recommend Charles Debug Proxy. Easiest combination for me is iPhone + Charles. iPhone allows you to redirect all your traffic to your local machine and then you can inspect what is going on by putting Charles in middle. Traffic is encrypted by SSL, so you need to install Charles root certificate first.

Session and cookies management:

So you said earlier there is a class gluing cookies and device, what?

The Session class is actually gluing any instance of CookieStorage and Device together. Every request to Instagram must be chained with proper headers and data, in order to make endpoints work. For example every endpoint requires a proper User-Agent header in order to verify signature or X-CSFR-Token | _csrftoken to verify that you are doing request intentionally.

CookieStorage & CookieFileStorage & CookieMemoryStorage

You can store cookies anywhere you want. Cookies are done with tough-cookie. Simple overview would be that, CookieStorage should have property store, which should be child instance of tough.Store class.

For more info checkout this:

tough.Store and internal class CookieFileStorage

var storage = new Client.CookieFileStorage(__dirname + './cookies/someuser.json');
// or simply var storage = new Client.CookieMemoryStorage();
storage.getAccountId()
	.then(function(accountId){
		console.log(accountId);
		// will return actual userId from cookies
	})

Session class

You can create a new instance of Session by calling var session = new Session(storage:CookieStorage, device:Device)

If you have valid cookies, you don't need to worry about anything else if you don't, you need to create a session with storage and device.

static method

Session.create(device:Device, storeage:CookieStorage, username:string, password:string, proxyUrl?:string)

can help you with that. This method will sign-in and create a new Session instance.

.getAccountId() : Promise<void|string>

this method returns the account id from cookies

.setProxy(proxyUrl:string)

this will set proper proxy-url. More about this below.

.getAccount() : Promise<Account>

will return the account object associated with your session.

// lets assume you got valid session
// var session = new Client.Session(device, storage)
session.getAccount()
  .then(function(account) {
	console.log(account.params)
	// {username: "...", ...}
  })

Device class

You can instantize new class, which will be able to represent it self as a device you are using to access instagram. By default it will generate device from list of devices (can be found at client/v1/devices.json).

Reason for username in arguments is that you need to have same device for same user every time when you access instagram API. This is done through correlated md5 username hash.

Also Device class is responsible for the phone_id property, which is often sent with other data. It is responsible for generating a correlated android-id.

var device = new Client.Device('username');
device.md5 // will return md5 of your username
device.md5int // will return md5 integer representation of your device
device.info // will give you device model information
device.resolution // will give you resolution of device
device.dpi // will give you dpi of device
device.api // android API
device.release // android release

device.userAgent() // will return useragent for device

device.userAgent method is very important for many reasons. One of them is that without proper user agent there is no way how you can access signed endpoints.

How to proxy every request:

There are 2 choices to proxy requests:

Proxy URL has a standard format:

Unauthenticated: http(s)://yourhost.com/
Authenticated: http(s)://user:pass@yourhost.com/

You can set a global proxy or default proxy by calling Client.Request.setProxy(proxyURL)
Or if you are interested in one proxy per session session.proxyUrl = proxyURL SAME AS session.setProxy(proxyURL)

If you use a combination of these two methods, the first one has lower priority, meaning that, if you set a global proxy, and then a session proxy, the session proxy will be used.

Static .create method also accepts the proxy as last (optional parameter)

Session.create(device, storage, username, password, proxyURL)

Resource classes:

InstagramResource class is the base class for every resource.

From this class inherit:

Account, Comment, Hashtag, Like, Location, Media, Relationship, Thread, ThreadItem, Upload

InstagramResource constructor accepts two arguments:

new InstagramResource(session: Session, params: Object)

This class is keeping the session and params of every resource class mentioned above.

Remember this example?

// let's assume you got a valid session
// var session = new Client.Session(device, storage)
session.getAccount()
  .then(function(account) {
	console.log(account.params)
	// {username: "...", ...}
  })

account.params actually came from InstagramResource.

Account static .getById implementation as an example:

Account.getById = function (session, id) {
    return new Request(session)
        .setMethod('GET')
        .setResource('userInfo', {id: id})
        .send()
        .then(function(data) {
			// data variable is a pure JSON object which will be parsed
			// by Account.prototype.parse and set as the top level property params 
            return new Account(session, data.user)
        })
};  

// Usage

Account.getById(session, '1234567')
	.then(function(account) {
		console.log(account.params);
		// {username: "...", ...}
		console.log(account.id);
		// only property which is exported as top level
		// property
	})

Another example would be upload:

// JPEG is the only supported format now, pull request for any other format welcomed!
Upload.photo(session, './path/to/your/jpeg.jpg')
	.then(function(upload) {
		// upload instanceof Client.Upload
		// nothing more than just keeping upload id
		console.log(upload.params.uploadId);
		return Media.configurePhoto(session, upload.params.uploadId, 'akward caption');
	})
	.then(function(medium) {
		// we configure medium, it is now visible with caption
		console.log(medium.params)
	})

Video upload:

// MP4 is the only supported format now, pull request for any other format welcomed!
Upload.video(session, './path/to/your/video.mp4','./path/to/your/coverImg.jpg')
	.then(function(upload) {
		return Media.configureVideo(session, upload.uploadId, 'akward caption', upload.durationms);
	})
	.then(function(medium) {
		// we configure medium, it is now visible with caption
		console.log(medium.params)
	})

Feeds

Feed is the class which implements functionality to iterate through a list (which can be an infinite list) of data, like user media or hashtag media or locations.

Every feed implements the method .get to help you go move the cursor and fetch items until you hit the bottom.

cursor is a sort of pagination for the API. Basically in every request you will receive the next cursor for next request, which will lead to another set of data for this specific feed.

Implemented are: AccountFollowers, AccountFollowing, UserMedia, LocationMedia, TaggedMedia, MediaComments, SelfLiked, TimelineFeed, Inbox, Thread

Feed API is the same almost every time:

var feed = new Client.Feed.UserMedia(session:Session, ...extraArguments)

Since feeds can be infinite and we cannot obviosly fetch all results, we need to iterate. Every time you call .get, you will receive a new set of data and set new cursor.

feed.get() : Promise<Media[]>

var _ = require('underscore');
var Promise = require('bluebird');

var accountId = '123456'
var feed = new Client.Feed.UserMedia(session, accountId);

Promise.mapSeries(_.range(0, 20), function() {
	return feed.get();
})
.then(function(results) {
	// result should be Media[][]
	var media = _.flatten(results);
	var urls = _.map(media, function(medium) {
		return _.last(medium.images)
	});
	console.log(urls);
})

feed.getCursor() : string

will return the current cursor, which will be set after calling .get

feed.setCursor() : void

will set new cursor, from which you can start to iterate

feed.isMoreAvailable() : Boolean

returns a boolean indicating if there is more data to fetch. Of course you can hit bottom and then there would be no other data to fetch.

Some feeds have more methods to make things easier. You can check them out.

Account Creator

AccountCreator and his children AccountEmailCreator, AccountPhoneCreator are designed to create an account. To make account you want to probably use either AccountEmailCreator or AccountPhoneCreator. AccountCreator it self is just abstraction.

Example of AccountEmailCreator:

// Create empty session
var session = new Client.Session(device, storage);
new AccountEmailCreator(session)
	.setEmail('....@....')
	.setUsername('nickname')
	.setPassword('pwd')
	.setName('Name')
	.register()
	.spread(function(account, discover) {
		// account instanceof Client.Account
		console.log("Created Account", account)
		console.log("Discovery Feed", discover);
	})

Example of AccountPhoneCreator:

// Create empty session
var session = new Client.Session(device, storage);
new AccountPhoneCreator(session)
	.setPhone('phone number ie 111222333')
	.setUsername('nickname')
	.setPassword('pwd')
	.setName('Name')
	.setPhoneCallback(function() {
		// This will be called in order to 
		// supply verification code, must return promise
		// with actual value
		return Promise.resolve("123456")
	})
	.register()
	.spread(function(account, discover) {
		// account instanceof Client.Account
		console.log("Created Account", account)
		console.log("Discovery Feed", discover);
	})

Serval exceptions can be raised.

InvalidEmail if you dont supply valid email
InvalidUsername if you dont have valid username
InvalidPhone for invalid phone number
InvalidPassword is you password is for example too short
AccountRegistrationError when instagram denied your code or registrion
AuthenticationError when account is created but you did not successfuly log in

If you tried too much for you testing purposes you can supply proxy to session. Check the "How to proxy every request" section.

Challenges

The Challenge class and its children are a way to somehow respond to Instagram verification requests. Let me tell you this first: I hope you will not spam Instagram, because they are providing a really great service and this repo should just be used for easier access to their API... Anyway Instagram is really freaking smart and aggressive about getting you banned for any malicious activity, so be careful Icarus and don't spam.

In case you don't have any malicious intentions and you get into a situation that requires you to verify via mail or phone, or to pass a captcha (not implemented yet, due to missing account for testing) you can use the challenge classes to automate this process.

Example first:

// var device, storage, user, password;
// you get those from previous examples

function challengeMe(error) {
	return Client.Web.Challenge.resolve(error)
		.then(function(challenge) {
			// challenge instanceof Client.Web.Challenge
			console.log(challenge.type);
			// can be phone, email, or captcha
			// let's assume we got email
			if(!challenge.type !== 'email') return;
			// Will send request to send email to you
			// email will be one associated with your account
			return challenge.email();
		})
		.then(function(challenge) {
			// Ok we got to the next step, the response code expected by Instagram
			return challenge.code('123456');
		})
		.then(function(challenge) {
			// Yey Instagram accepted the code
			// now we confirmed that Instagram is happy, weird :P
			return challenge.confirmate()
		})
		.then(function(challenge) {
			// And we got the account confirmed!
			// so let's login again
			return loginAndFollow(device, storage, user, password);
		})

}


function loginAndFollow(device, storage, user, password) {
	return Client.Session.create(device, storage, user, password)
		.then(function(session) {
			// Now you have a session, we can follow / unfollow, anything...
			// And we want to follow Instagram official profile
			return [session, Client.Account.searchForUser(session, 'instagram')]   
		})
		.spread(function(session, account) {
			return Client.Relationship.create(session, account.id);
		})
}


loginAndFollow(device, storage, user, password)
	.catch(Client.Exceptions.CheckpointError, function(error){
		// Ok now we know that Instagram is asking us to
		// prove that we are real users
		return challengeMe(error);
	}) 
	.then(function(relationship) {
		console.log(relationship.params)
		// {followedBy: ... , following: ... }
		// Yey, you just followed an account
	});

More common for such a situation is PhoneVerification. Of course there are services like textnow.com and others which will provide an API to let you receive Instagram SMS messages!
