WordPress Instagram Basic Display integration

Description

Enables Instagram Basic Display API for developers.

The idea of the plugin is to use Instagram Basic Display PHP API with ability to get access token through WordPress admin panel.

Install

• Preferable way is to use Composer:

  composer require innocode-digital/wp-instagram
  

• Alternate way is to clone this repo to wp-content/plugins/:

  cd wp-content/plugins/
  git clone git@github.com:innocode-digital/wp-instagram.git
  cd wp-instagram/
  composer install
  

Activate WordPress Instagram Basic Display integration with WP-CLI wp plugin activate wp-instagram or from Plugins page.

Usage

1. Check Facebook Manual on how to create an APP.

2. Add required constants (usually to wp-config.php):

   define( 'INSTAGRAM_CLIENT_ID', '' );
   define( 'INSTAGRAM_CLIENT_SECRET', '' );
   

3. Add site auth URL https://site.com/instagram/auth/ to Valid OAuth Redirect URIs in Basic Display.

4. Open settings page in WordPress admin panel Settings -> Instagram /wp-admin/options-general.php?page=innocode-instagram

5. Click on Log in button or Log in as another user in case when should change account.

6. Start use Instagram Basic Display PHP API through innocode_instagram(); function e.g. innocode_instagram()->getUserProfile();.

7. (optional) Set site deauth REST API endpoint https://site.com/wp-json/innocode/v1/instagram/deauth in Deauthorize Callback URL in Basic Display.

Notes

If site is a part of Multisite then main site auth URL should be added in Valid OAuth Redirect URIs. So, plugin should be active on all network or at least on the main site additionally.

Plugin adds daily cron job after authorization. So, please be sure cron functionality works. The token tries to update 3 days before the expiration, user profile data updated daily.

Documentation

By default, endpoint auth URL is using instagram as endpoint, but it's possible to change with constant:

define( 'INNOCODE_INSTAGRAM_ENDPOINT', 'insta' );

App site

If you want to use one APP for all of your sites where Instagram integration is in use and correctly handle deauthorization process then this plugin could be installed additionally on a site which will store user IDs and URLs of sites where these IDs are using, e.g. this could be a site of your company. Then it's needed to set one more constant on all sites with activated plugin.

define( 'INNOCODE_INSTAGRAM_APP_SITE', 'https://app-site.com' );

It's possible to change full auth URL:

add_filter( 'innocode_instagram_redirect_uri', function ( string $url ) {
    return $url;
} );

It's possible to change Instagram permission:

add_filter( 'innocode_instagram_scope', function ( array $scope ) {
    return $scope; // Default is array containing 'user_profile' and 'user_media'.
} );

It's possible to change state parameter which is sending with auth request:

add_filter( 'innocode_instagram_state', function ( string $state ) {
    return $scope; // Default is string in format '$blog_id:$nonce'.
} );

It's possible to change place where endpoint should be added:

add_filter( 'innocode_instagram_endpoint_mask', function ( $mask, $endpoint ) {
    return $mask; // Default is EP_ROOT constant.
}, 10, 2 );
