Image Instagram PHP API V2

About

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

Supports Instagram video responses.

Requirements

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

Get started

Register your application with Instagram, and receive your OAuth client_id and client_secret.
Take a look at the uri guidlines before registering a redirect URI.

A good place to get started is the example App.

Initialize the class

<?php
    require_once 'instagram.class.php';

    $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
    // Store 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:

Scope Legend Methods
basic to use all user related methods [default] getUser(), getUserFeed(), getUserFollower() etc.
relationships to follow and unfollow users modifyRelationship()
likes to like and unlike items getMediaLikes(), likeMedia(), deleteLikedMedia()
comments to create or delete comments getMediaComments(), addMediaComment(), deleteMediaComment()

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

Stores access token, for further method calls:
setAccessToken($token)

Returns 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, 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.


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

Registered Redirect URI Redirect URI sent to /authorize Valid?
http://yourcallback.com/ http://yourcallback.com/ yes
http://yourcallback.com/ http://yourcallback.com/?this=that yes
http://yourcallback.com/?this=that http://yourcallback.com/ no
http://yourcallback.com/?this=that http://yourcallback.com/?this=that&another=true yes
http://yourcallback.com/?this=that http://yourcallback.com/?another=true&this=that no
http://yourcallback.com/callback http://yourcallback.com/ no
http://yourcallback.com/callback http://yourcallback.com/callback/?type=mobile yes

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.
