Headhunter OAuth2 strategy for Überauth.

1. Setup your application at https://headhunter.readme.io/docs/marketplace-oauth-authorization.

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

   def deps do
     [
       {:ueberauth_headhunter, "~> 0.0.3"}
     ]
   end

3. Add Headhunter to your Überauth configuration:

   config :ueberauth, Ueberauth,
     providers: [
       headhunter: {Ueberauth.Strategy.Headhunter, []}
     ]

4. Update your provider configuration:

   Use that if you want to read client ID/secret from the environment variables in the compile time:

   config :ueberauth, Ueberauth.Strategy.Headhunter.OAuth,
     client_id: System.get_env("HEADHUNTER_CLIENT_ID"),
     client_secret: System.get_env("HEADHUNTER_CLIENT_SECRET")

   Use that if you want to read client ID/secret from the environment variables in the run time:

   config :ueberauth, Ueberauth.Strategy.Headhunter.OAuth,
     client_id: {System, :get_env, ["HEADHUNTER_CLIENT_ID"]},
     client_secret: {System, :get_env, ["HEADHUNTER_CLIENT_SECRET"]}

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
   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.

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

/auth/headhunter
