Connect to API that needs an access token with PHP (without Laravel) - php

Question

I'm trying to access to an API that needs and Access Token but I don't know how to implement the token part. This is how I connect to the API. What is wrong in my code?
$ch = curl_init();
$authorization = 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJub25jZSI6Im5aTHhod...';
$headers = array(
'Content-type: application/json',
$authorization,
);
curl_setopt($ch, CURLOPT_URL, "https://graph.microsoft.com/v1.0/me/onenote/notebooks");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$res = curl_exec($ch);
curl_close($ch);
echo $res;

Just a matter of constructing the header, give this a try:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => 'https://graph.microsoft.com/v1.0/me/onenote/notebooks',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => '',
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => 'GET',
CURLOPT_HTTPHEADER => array(
'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJub25jZSI6Im5aTHhod'
),
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;
