Hey there! Let's fix that issue with accessing LinkedIn's extended fields (like publicProfileUrl, positions, and summary) from Laravel Socialite's response. Here's what's going on and how to solve it:

The Problem #

Socialite's Laravel\Socialite\Two\User object stores the raw LinkedIn API response in a protected $user property—this means you can't directly access it with $linkedin_user->user or array-style indexing like $linkedin_user['user']. Your previous attempts failed because of this protected access restriction.

The Solution #

Use Socialite's built-in method to retrieve the full raw API response, then access the fields you need normally:

1. Get the raw user data
   Socialite provides a raw() method (or getRaw() in older versions) that returns the complete array of data from LinkedIn's API:

   $rawLinkedInData = $linkedin_user->raw();
   

2. Access your target fields
   Now you can pull out publicProfileUrl, summary, positions, etc., using standard array access (with null coalescing to handle missing data gracefully):

   $publicProfileUrl = $rawLinkedInData['publicProfileUrl'] ?? null;
   $summary = $rawLinkedInData['summary'] ?? null;
   // For positions, grab the values array (handle empty cases)
   $positions = $rawLinkedInData['positions']['values'] ?? [];
   

3. Save to your database
   Update your user creation code to include these fields. If you're storing structured data like positions, use json_encode() to save it as a JSON column in your database:

   $user = User::where('provider_id', $linkedin_user->getId())->first();
   
   if (!$user) {
       $user = new User;
       $user->name = $linkedin_user->getName();
       $user->email = $linkedin_user->getEmail();
       $user->picture = $linkedin_user->getAvatar();
       $user->provider_id = $linkedin_user->getId();
       $user->access_token = $linkedin_user->token;
       
       // Add the LinkedIn-specific fields
       $user->linkedin_profile_url = $publicProfileUrl;
       $user->linkedin_summary = $summary;
       $user->linkedin_positions = json_encode($positions);
       
       $user->save();
   }
   

Quick Check: Permissions #

One last thing—make sure your LinkedIn app has the correct API permissions to retrieve these fields! For example:

• r_liteprofile gives access to basic profile data (name, avatar)
• To get summary, positions, and publicProfileUrl, you may need additional permissions like r_fullprofile (verify LinkedIn's current API docs for exact requirements, as permissions are occasionally updated).

If you don't have the right permissions, LinkedIn won't return those fields in the response—so double-check your app's settings on the LinkedIn Developer Portal.
