This is the unofficial OmniAuth strategy for authenticating to Instagram. To use it, you'll need to sign up for an OAuth2 Application ID and Secret on the Instagram Developer website.
use OmniAuth::Builder do
provider :instagram, ENV['INSTAGRAM_ID'], ENV['INSTAGRAM_SECRET']
end
P.S: Instagram has started enforcing signed requests for its API. If you have enabled Enforce signed requests in your app then, you can pass enforce_signed_requests: true in the above configuration. More info: https://instagram.com/developer/secure-api-requests/
