PHP laravel Referral System

I had made a website on PHP Laravel framework now i need to integrate referral system like User 2 will sign up using User1's referral id and then after successful signup user1 will get 100 points in his account.
Website is : (bazaarscanner.com)
and my-account : (www.bazaarscanner.com/my-account)
Please help me with the code and even i need to put that referral code system into social login?

            <?php

                @forelse(auth()->user()->getReferrals() as $referral)
                <h4>
                    
                </h4>
                <code>
                    
                </code>
                <p>
                    Number of referred users: 
                </p>
            @empty
