i try to tet google analytics property data using php curl api

Question

Please someone help me, I'm stuck in this problem since last 7 days...

I want to do something like this. Suppose i have multiple users property id, Client ID and Client secret and i using this API :

$apiEndpoint = 'https://analyticsdata.googleapis.com/v1beta/properties/'.env('ANALYTICS_PROPERTY_ID').':runReport';

Now I want to get Google Analytics data of particular user. And My Curl code this :

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => $apiRequestEndpoint,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POSTFIELDS => $requestData,
    CURLOPT_HTTPHEADER => array(
        'Content-Type: application/json',
        'Authorization: Bearer '.$accessToken
    ),
));

$response = curl_exec($curl);

curl_close($curl);

return $response;

$requestData = [
                'dateRanges' => [
                    [
                       'startDate' => $request->startDate,
                        'endDate' => $request->endDate
                    ]
                ],
                'dimensions' => [
                    [
                        'name' => 'sessionDefaultChannelGroup'
                    ],
                    [
                        'name' => 'date'
                    ]
                ],
                'metrics' => [
                    [
                        'name' => 'totalUsers'
                    ],
                ],
                'dimensionFilter' => [
                    'filter' => [
                        'fieldName' => 'sessionDefaultChannelGroup',
                        'inListFilter' => [
                            'values' => ['Organic Search']
                        ]
                    ]
                ],
                'orderBys' => [
                    [
                        'dimension' => [
                            'orderType' => 'NUMERIC',
                            'dimensionName' => 'date'
                        ]
                    ]
                ],
                'keepEmptyRows' => true,
                'metricAggregations' => [
                    'TOTAL'
                ]
            ];

Generate access token code here :

use Google_Client;
use Google_Service_Analytics;

$client = new Google_Client();
        
// Set OAuth2 credentials
$client->setClientId($request->client_id);
$client->setClientSecret($request->client_secret);

$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);

// Set the correct redirect URI
$client->setRedirectUri('http://127.0.0.1:8000/goback');

if (!isset($_GET['code'])) {
    $authUrl = $client->createAuthUrl();
    
    return redirect($authUrl);
}

// Exchange authorization code for an access token
$client->fetchAccessTokenWithAuthCode($_GET['code']);
$jsonData = $client->getAccessToken();    

// Get the access token
if (isset($jsonData['access_token'])) { 
    $accessToken = $jsonData['access_token'];
    return $accessToken;
} else {
    return 'Access token not found in the JSON data.'
    }

Note : Whenever I get google analytics date from a client. I have to login my google account every time.

So, I wish I don't have to login to my Gmail Account and get an access token for call a API. Can I do this and how ?

And I'm doing this feature in backend side PHP Laravel framework

composer require google/apiclient
