Instagram PHP API V2

About

A PHP wrapper for the Instagram API. Feedback or bug reports are appreciated.

Composer package available.
Supports Instagram Video and Signed Header.

Requirements

• PHP 5.2.x or higher
• cURL
• Registered Instagram App

Get started

To use the Instagram API you have to register yourself as a developer at the Instagram Developer Platform and create an application. Take a look at the uri guidlines before registering a redirect URI. You will receive your client_id and client_secret.

Please note that Instagram mainly refers to »Clients« instead of »Apps«. So »Client ID« and »Client Secret« are the same as »App Key« and »App Secret«.

A good place to get started is the example project.

Installation

I strongly advice using Composer to keep updates as smooth as possible.

Initialize the class

<?php
    require_once 'Instagram.php';
    use MetzWeb\Instagram\Instagram;

    $instagram = new Instagram(array(
      'apiKey'      => 'YOUR_APP_KEY',
      'apiSecret'   => 'YOUR_APP_SECRET',
      'apiCallback' => 'YOUR_APP_CALLBACK'
    ));

    echo "<a href='{$instagram->getLoginUrl()}'>Login with Instagram</a>";
?>

Authenticate user (OAuth2)

<?php
    // grab OAuth callback code
    $code = $_GET['code'];
    $data = $instagram->getOAuthToken($code);

    echo 'Your username is: ' . $data->user->username;
?>

Get user likes

<?php
    // set user access token
    $instagram->setAccessToken($data);

    // get all user likes
    $likes = $instagram->getUserLikes();

    // take a look at the API response
    echo '<pre>';
    print_r($likes);
    echo '<pre>';
?>

All methods return the API data json_decode() - so you can directly access the data.

Available methods

Setup Instagram

new Instagram(<array>/<string>);

array if you want to authenticate a user and access its data:

new Instagram(array(
  'apiKey'      => 'YOUR_APP_KEY',
  'apiSecret'   => 'YOUR_APP_SECRET',
  'apiCallback' => 'YOUR_APP_CALLBACK'
));

string if you only want to access public data:

new Instagram('YOUR_APP_KEY');

Get login URL

getLoginUrl(<array>)

getLoginUrl(array(
  'basic',
  'likes'
));

Optional scope parameters:

Get OAuth token

getOAuthToken($code, <true>/<false>)

true : Returns only the OAuth token
false [default] : Returns OAuth token and profile data of the authenticated user

Set / Get access token

• Set the access token, for further method calls: setAccessToken($token)
• Get the access token, if you want to store it for later usage: getAccessToken()

User methods

Public methods

• getUser($id)
• searchUser($name, <$limit>)
• getUserMedia($id, <$limit>)

Authenticated methods

• getUser()
• getUserLikes(<$limit>)
• getUserFeed(<$limit>)
• getUserMedia(<$id>, <$limit>)
  • if an $id isn't defined or equals 'self', it returns the media of the logged in user

Sample responses of the User Endpoints.

Relationship methods

Authenticated methods

• getUserFollows($id, <$limit>)
• getUserFollower($id, <$limit>)
• getUserRelationship($id)
• modifyRelationship($action, $user)
  • $action : Action command (follow / unfollow / block / unblock / approve / deny)
  • $user : Target user id

<?php
    // Follow the user with the ID 1574083
    $instagram->modifyRelationship('follow', 1574083);
?>

Please note that the modifyRelationship() method requires the relationships scope.

Sample responses of the Relationship Endpoints.

Media methods

Public methods

• getMedia($id)
• getPopularMedia()
• searchMedia($lat, $lng, <$distance>, <$minTimestamp>, <$maxTimestamp>)
  • $lat and $lng are coordinates and have to be floats like: 48.145441892290336,11.568603515625
  • $distance : Radial distance in meter (default is 1km = 1000, max. is 5km = 5000)
  • $minTimestamp : All media returned will be taken later than this timestamp (default: 5 days ago)
  • $maxTimestamp : All media returned will be taken earlier than this timestamp (default: now)

Sample responses of the Media Endpoints.

Comment methods

Public methods

• getMediaComments($id)

Authenticated methods

• addMediaComment($id, $text)
  • restricted access: please email apidevelopers[at]instagram.com for access
• deleteMediaComment($id, $commentID)
  • the comment must be authored by the authenticated user

Please note that the authenticated methods require the comments scope.

Sample responses of the Comment Endpoints.

Tag methods

Public methods

• getTag($name)
• getTagMedia($name)
• searchTags($name)

Sample responses of the Tag Endpoints.

Likes methods

Authenticated methods

• getMediaLikes($id)
• likeMedia($id)
• deleteLikedMedia($id)

How to like a Media: Example usage Sample responses of the Likes Endpoints.

All <...> parameters are optional. If the limit is undefined, all available results will be returned.

Instagram videos

Instagram entries are marked with a type attribute (image or video), that allows you to identify videos.

An example of how to embed Instagram videos by using Video.js, can be found in the /example folder.

Please note: Instagram currently doesn't allow to filter videos.

Signed Header

In order to prevent that your access tokens gets stolen, Instagram recommends to sign your requests with a hash of your API secret and IP address.

1. Activate "Enforce Signed Header" in your Instagram client settings.

2. Enable the signed-header in your Instagram class:

   $instagram->setSignedHeader(true);

3. You are good to go! Now, all your POST and DELETE requests will be secured with a signed header.

Go into more detail about how it works in the Instagram API Docs.

Pagination

Each endpoint has a maximum range of results, so increasing the limit parameter above the limit won't help (e.g. getUserMedia() has a limit of 90).

That's the point where the "pagination" feature comes into play. Simply pass an object into the pagination() method and receive your next dataset:

<?php
    $photos = $instagram->getTagMedia('kitten');

    $result = $instagram->pagination($photos);
?>

Iteration with do-while loop.

Samples for redirect URLs

If you need further information about an endpoint, take a look at the Instagram API docs.

Example App

This example project, located in the example/ folder, helps you to get started. The code is well documented and takes you through all required steps of the OAuth2 process. Credit for the awesome Instagram icons goes to Ricardo de Zoete Pro.
