I plan to have a webapp for user to upload file to my drive. I create a service account and get the OAuth token for Google Picker. I confirm the access token is vaild. However, Google Picker API returns 403. It only works if I login with my account ('[email protected]').
I have searched many days, but still do not have a solution for that. Any comments are appreciated.
Here is my code.
<?php
require_once '/vendor/autoload.php';
use Google\Client;
use Google\Service\Drive;
$client = new Client();
$client->setAuthConfig('service_account.json');
$client->setApplicationName("GooglePickerAPI");
$client->setScopes(['https://www.googleapis.com/auth/drive.file']);
$client->setSubject('[email protected]');
$client->setAccessType('offline');
$client->authorize()->get('https://www.googleapis.com/auth/drive.file');
// Get the access token
$accessToken = $client->getAccessToken();
$accessTokenJson = json_encode($accessToken);
?>

This seems a recent issue and is happening globally. This might not have anything with the code, its issue from Google itself. Please find the below link to track this issue. https://issuetracker.google.com/issues/328843663
