Facebook Marketing API and Ads Insight Access – Facebook api

Derks, I currently am building dashboard with over 40 clients and I am able to display everyone of them and their insights data etc. with basic development level. I have code if you want to take a look only thing I am trying to accomplish now is making a date range picker but, you are more than welcome enough to take a look at what I have just to get a general idea.

Here are the Use objects from Facebook

<?php

        require_once __DIR__ . '/vendor/autoload.php';
        use FacebookAdsApi;
        use FacebookAdsObjectAdUser;
        use FacebookFacebook;
        use FacebookExceptionsFacebookResponseException;
        use FacebookExceptionsFacebookSDKException;
        use FacebookAdsObjectCampaign;
        use FacebookAdsObjectFieldsAdsInsightsFields;
        use FacebookAdsObjectAd;
        use FacebookAdsObjectFieldsAdSetFields;
        use FacebookAdsObjectAdCampaign;
        use FacebookAdsObjectFieldsAdFields;
        use FacebookAdsObjectFields;
        use FacebookAdsObjectFieldsAdImageFields;
        use FacebookAdsObjectAdAccount;
        use FacebookAdsObjectAdSet;
        use FacebookAdsObjectAdCreative;
        use FacebookAdsObjectFieldsAdCreativeFields;
        use FacebookAdsObjectFieldsAdCreativePhotoDataFields;
        use FacebookAdsObjectAdCreativeLinkData;
        use FacebookAdsObjectFieldsAdCreativeLinkDataFields;
        use FacebookAdsObjectFieldsCampaignFields;
        use FacebookAdsObjectPage;
        use FacebookAdsObjectFieldsAdPreviewFields;
        use FacebookAdsObjectValuesAdPreviewAdFormatValues;
        use FacebookAdsObjectAdVideo;
        ?>

Here is the general code I am trying

<?php
        // Init PHP Sessions
        session_start();

        $fb = new Facebook([
          'app_id' => 'xxxxxxxxx',
          'app_secret' => 'xxxxxxxxxxx',
        ]);

        $helper = $fb->getRedirectLoginHelper();

        if (!isset($_SESSION['enter api key here'])) {
          $_SESSION['enter api key here'] = null;
        }

        if (!$_SESSION['enter api key here']) {
          $helper = $fb->getRedirectLoginHelper();
          try {
            $_SESSION['enter api key here'] = (string) $helper->getAccessToken();
          } catch(FacebookResponseException $e) {
            // When Graph returns an error
            echo 'Graph returned an error: ' . $e->getMessage();
            exit;
          } catch(FacebookSDKException $e) {
            // When validation fails or other local issues
            echo 'Facebook SDK returned an error: ' . $e->getMessage();
            exit;
          }
        }

        if ($_SESSION['enter api key here']) {
          //echo "You are logged in!";

        // Initialize a new Session and instantiate an API object
        Api::init(
          'xxxxxxxxx', // App ID
          'xxxxxxxxx', //app_secret
          $_SESSION['enter api key here'] // Your user access token
        );

    ?>

I will help much as I can @Derks and I believe the only thing you may need to do is figure out way for the program or whatever your building know who is who.
