PayPal Payout API REQUIRED_SCOPE_MISSING - php

Question

I am trying to implement payout request using CURL. But I am getting this error: "name":"REQUIRED_SCOPE_MISSING","message":"Access token does not have required scope.","information_link":"https://developer.paypal.com/docs/api/payments.payouts-batch/#errors"
I have already checked on payouts scope in-app settings on developer dashboard.
Here is code:
$host = 'https://api.sandbox.paypal.com';
$clientId = 'id';
$secret = "secret";
$token = '';
function get_access_token($url, $postdata) {
global $clientId, $clientSecret;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_USERPWD, $clientId . ":" . $clientSecret);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata);
$response = curl_exec( $curl );
if (empty($response)) {
die(curl_error($curl));
curl_close($curl);
} else {
$info = curl_getinfo($curl);
echo "Time took: " . $info['total_time']*1000 . "ms\n";
curl_close($curl);
if($info['http_code'] != 200 && $info['http_code'] != 201 ) {
echo "Received error: " . $info['http_code']. "\n";
echo "Raw response:".$response."\n";
die();
}
}
$jsonResponse = json_decode( $response );
return $jsonResponse->access_token;
}
function make_post_call($url, $postdata) {
global $token;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Authorization: Bearer '.$token,
'Accept: application/json',
'Content-Type: application/json'
));
curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata);
$response = curl_exec( $curl );
if (empty($response)) {
die(curl_error($curl));
curl_close($curl);
} else {
$info = curl_getinfo($curl);
echo "Time took: " . $info['total_time']*1000 . "ms\n";
curl_close($curl); // close cURL handler
if($info['http_code'] != 200 && $info['http_code'] != 201 ) {
echo "Received error: " . $info['http_code']. "\n";
echo "Raw response:".$response."\n";
die();
}
}

print_r($jsonResponse); die;
return $jsonResponse;
