InstagramPublishApiViaInstagramLogin

A Ruby gem for publishing media to Instagram using Instagram Basic Display API and Instagram Graph API. This gem provides a simple interface to authenticate users via Instagram Login and publish images, videos, and carousel posts to their Instagram accounts.

Before using this gem, you need to:

1. Create a Facebook App and configure Instagram Basic Display API
2. Set up Instagram Basic Display API permissions
3. Configure OAuth redirect URIs in your Facebook App settings
4. Obtain your Instagram Business Account ID

Add this line to your application's Gemfile:

gem 'instagram_publish_api_via_instagram_login'

And then execute:

bundle install

Or install it yourself as:

gem install instagram_publish_api_via_instagram_login

This gem provides three independent classes for working with Instagram API:

require 'instagram_publish_api_via_instagram_login'

# Create authenticator
authenticator = InstagramPublishApiViaInstagramLogin::Authenticator.new(
  client_id: 'your_instagram_app_id',
  client_secret: 'your_instagram_app_secret',
  redirect_uri: 'your_redirect_uri'
)

# Exchange code for token
response = authenticator.exchange_code_for_token(authorization_code)
access_token = response['access_token']

# Create user details instance
user_details = InstagramPublishApiViaInstagramLogin::UserDetails.new(
  access_token: access_token
)

# Get user info
user_info = user_details.get_user_info(
  fields: 'id,username,account_type'
)

# Get long-lived access token (60 days)
long_lived_token = user_details.get_long_lived_access_token(
  client_secret: 'your_app_secret'
)

# Refresh access token (extends for another 60 days)
refreshed_token = user_details.refresh_access_token

# Create publisher with access token
publisher = InstagramPublishApiViaInstagramLogin::Publisher.new(
  access_token: access_token
)

# Publish single image
result = publisher.publish_media(
  ig_id: instagram_business_account_id,
  media_url: 'https://example.com/image.jpg',
  media_type: 'IMAGE'
)

# Publish image with caption
result = publisher.publish_media(
  ig_id: instagram_business_account_id,
  media_url: 'https://example.com/image.jpg',
  media_type: 'IMAGE',
  caption: 'Beautiful sunset! 🌅 #nature #photography'
)

# Publish carousel with caption
result = publisher.publish_media(
  ig_id: instagram_business_account_id,
  media_url: [
    'https://example.com/image1.jpg',
    'https://example.com/image2.jpg'
  ],
  media_type: 'CAROUSEL',
  caption: 'Photo collection from my trip ✈️ #travel #memories'
)

# That's it! publish_media handles everything automatically:
# - Creates media container(s)
# - Waits for processing to complete  
# - Publishes the media

The gem includes comprehensive error handling for API responses:

begin
  result = client.publish_media(
    ig_id: instagram_business_account_id,
    access_token: access_token,
    media_url: 'https://example.com/image.jpg'
  )
rescue InstagramPublishApiViaInstagramLogin::Error => e
  puts "Error: #{e.message}"
end

• IMAGE - Single images (JPEG, PNG) with optional caption
• VIDEO - Single videos (MP4, MOV) with optional caption
• REELS - Instagram Reels with optional caption
• STORIES - Instagram Stories with optional caption
• CAROUSEL - Multiple images in a single post with optional caption (automatically handled when passing an array of URLs)

Features:

• Captions - Add text descriptions, hashtags, and mentions to your posts
• Token Management - Get long-lived tokens and refresh existing tokens

Note: Currently, carousel posts support only images. Support for mixed media types (images + videos) in carousels will be added in future versions.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
