Überauth LinkedIn

LinkedIn v2 OAuth2 strategy for Überauth.

Installation

1. Setup your application at LinkedIn Developers.

2. Add :ueberauth_linkedin to your list of dependencies in mix.exs:

   def deps do
     [{:ueberauth_linkedin, "~> 0.10.8", hex: :ueberauth_linkedin_modern}]
   end
   

3. Add LinkedIn to your Überauth configuration:

   config :ueberauth, Ueberauth,
     providers: [
       linkedin: {Ueberauth.Strategy.LinkedIn, []}
     ]
   

4. Update your provider configuration:

   config :ueberauth, Ueberauth.Strategy.LinkedIn.OAuth,
     client_id: System.get_env("LINKEDIN_CLIENT_ID"),
     client_secret: System.get_env("LINKEDIN_CLIENT_SECRET"),
     redirect_uri: System.get_env("LINKEDIN_REDIRECT_URI")
   

5. Include the Überauth plug in your controller:

   defmodule MyApp.AuthController do
     use MyApp.Web, :controller
     plug Ueberauth
     ...
   end
   

6. Create the request and callback routes if you haven't already:

   scope "/auth", MyApp do
     pipe_through :browser
   
     get "/:provider", AuthController, :request
     get "/:provider/callback", AuthController, :callback
     post "/:provider/callback", AuthController, :callback
   end
   

7. Your controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

For an example implementation see the Überauth Example application.

Calling

Depending on the configured url you can initiate the request through:

/auth/linkedin?state=csrf_token_here

Or with scope:

/auth/linkedin?state=csrf_token_here&scope=r_emailaddress

By default the requested scope is "openid profile email". Scope can be configured either explicitly as a scope query value on the request path or in your configuration:

config :ueberauth, Ueberauth,
  providers: [
    linkedin: {Ueberauth.Strategy.LinkedIn, [default_scope: "openid profile email"]}
  ]
