How to get all properties for Google Analytics GA4 accounts

Question

How do I list all properties for all account using Google Analytics GA4 through PHP? For universal analyitcs I'm using the following:

function initializeAnalyticsV3()
{
    $client = new Google_Client();
    $client->setApplicationName("Name");
    $client->setAuthConfig($KEY_FILE_LOCATION);
    $client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);
    $analytics = new Google_Service_Analytics($client);

    return $analytics;
}

$analyticsV3 = initializeAnalyticsV3();

try {
    $accounts = $analyticsV3->management_accountSummaries
        ->listManagementAccountSummaries();
} catch (apiServiceException $e) {
    print 'There was an Analytics API service error '
        . $e->getCode() . ':' . $e->getMessage();
} catch (apiException $e) {
    print 'There was a general API error '
        . $e->getCode() . ':' . $e->getMessage();
}

foreach ($accounts->getItems() as $account) {
    foreach ($account->getWebProperties() as $property) {
        $profile = $property->getProfiles();
        [...]
    }
}

However, this method only allows me to retrieve Universal analytics properties, not the new GA4 ones. The official documentation was of no help at all.

Google analytics GA4 is not the same as universal analytics.

You can use the managment api to list all of the properties for Univeral analytics acocunts.

$accounts = $analytics->management_accounts->listManagementAccounts();

You will need to use the Admin api to list the Ga4 accounts.

GET https://analyticsadmin.googleapis.com/v1alpha/accountSummaries

  "accountSummaries": [
    {
      object (AccountSummary)
    }
  ],
  "nextPageToken": string
}

At the time of writing they have not released a PHP client library for the Admin api yet. I will update with a link to it when it is released.

[update] The client libraries are available now at https://developers.google.com/analytics/devguides/config/admin/v1/client-libraries#php
