PHP - Google Sheets API OAuth2- can't get token - php

Question

i am trying to create a token/refreshToken so my website will be able to submit data to Google Sheets without asking the end user for permissions and i am struggling with this for few hours now..
I tried many different codes i found on the web + Google's docs and i made some progress but i can't get it to work and i can't figure what i am missing..
At this point i get no error (neither in my logs) but also i don't get any redirect or new window for authorizing the app
<?php
session_start();
require_once('php-google-oauth/Google_Client.php');
include_once('lib/autoload.php');
include_once('php-google-oauth/auth/Google_OAuth2.php');
$CLIENT_ID = 'xxxxxxxxxxxx.apps.googleusercontent.com';
$SECRET = 'xxxxxxxxxxxxxxxxxxxxxxxx';
$REDIRECT = 'http://mywebsite.com';
$APIKEY = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
// $KEY = file_get_contents('php-google-oauth/client_secret.json');
$client = new Google_Client();
$client->setApplicationName("Contacts to Google Sheets");
$client->setClientId($CLIENT_ID);
$client->setClientSecret($SECRET);
$client->setRedirectUri($REDIRECT);
$client->setScopes(array('https://spreadsheets.google.com/feeds'));
$client->setAccessType('offline'); // Gets us our refresh token
// Step 1: The user has not authenticated so we give them a link to login
if (!$client->getAccessToken() && !isset($_SESSION['token'])) {
$authUrl = $client->createAuthUrl();
}
// Step 2: The user accepted your access now you need to exchange it.
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: ' . filter_var($REDIRECT, FILTER_SANITIZE_URL));
}
// Step 3: We have access we can now create our service
if (isset($_SESSION['token'])) {
$client->setAccessToken($_SESSION['token']);
$token = $client->getAccessToken();
}
echo '<script>console.log("TOKEN: '. $token .'");</script>';
?>
Thanks in advance!

Answer 1

I looked at my code and tried this-
// Step 1: The user has not authenticated so we give them a link to login
if (!$client->getAccessToken() && !isset($_SESSION['token'])) {
$authUrl = $client->createAuthUrl();
echo 'Click here';
}
and now i do get a token back from Google
