Logging in using LinkedIn

If we don't want to worry about storing user's information and credentials, we could use OAuth to authenticate with another service. A popular service to use for logins, especially for business applications, is LinkedIn. With Laravel and the HybridAuth library, we can easily implement OAuth authentication with LinkedIn.

Getting ready

For this recipe, we need to have the HybridAuth package installed and set up as in the Setting up OAuth with the HybridAuth package recipe.

How to do it...

To complete this recipe, follow these steps:

1. Create a new app at https://www.linkedin.com/secure/developer.

2. Get the API Key and the Secret Key, and in the app/config directory, create a file named li_auth.php:

   <?php
   return array(
       "base_url"   => "http://path/to/our/app/liauth/auth",
       "providers"  => array (
           "LinkedIn" => array (
               "enabled" => true,
               "keys"    => array ("key" => "API_KEY","secret" => "SECRET_KEY")
           )
     ...
