A LinkedIn OAuth2 strategy for OmniAuth.
For more details, read the LinkedIn documentation: https://developer.linkedin.com/documents/authentication
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install omniauth-linkedin-oauth2
Previous versions of this gem used the provider name
:linkedin_oauth2. In order to provide a cleaner upgrade path for users who were previously using the OAuth 1.0 omniauth adapter for LinkedIn [https://github.com/skorks/omniauth-linkedin], this has been renamed to just
Users who are upgrading from previous versions of this gem may need to update their Omniauth and/or Devise configurations to use the shorter provider name.
Register your application with LinkedIn to receive an API key: https://www.linkedin.com/secure/developer
This is an example that you might put into a Rails initializer at
Rails.application.config.middleware.use ::Builder do provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'] end
You can now access the OmniAuth LinkedIn OAuth2 URL:
Granting Member Permissions to Your Application
With the LinkedIn API, you have the ability to specify which permissions you want users to grant your application. For more details, read the LinkedIn documentation: https://developer.linkedin.com/documents/authentication
By default, omniauth-linkedin-oauth2 requests the following permissions:
You can configure the scope option:
provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'], :scope => 'r_fullprofile r_emailaddress r_network'
When specifying which permissions you want to users to grant to your application, you will probably want to specify the array of fields that you want returned in the omniauth hash. The list of default fields is as follows:
['id', 'email-address', 'first-name', 'last-name', 'headline', 'location', 'industry', 'picture-url', 'public-profile-url']
Here's an example of a possible configuration where the the fields returned from the API are: id, email-address, first-name and last-name.
provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'], :fields => ['id', 'email-address', 'first-name', 'last-name']
To see a complete list of available fields, consult the LinkedIn documentation at: https://developer.linkedin.com/documents/profile-fields
