403 forbidden error coinbase api

Question

I am using the following code:

<?php

require_once 'vendor/autoload.php';

use Coinbase\Wallet\Client;
use Coinbase\Wallet\Configuration;
use Coinbase\Wallet\Resource\Address;
use Coinbase\Wallet\Resource\Account;

$apiKey = '**********';
$apiSecret = '*************';
$configuration = Configuration::apiKey($apiKey, $apiSecret);
$client = Client::create($configuration);

try {
    $buyPrice = $client->getBuyPrice('BTC-USD');
} catch (Exception $exc) {
    echo '<pre>';
    echo $exc->getTraceAsString();
    echo '<hr/>';
    echo $exc->getMessage();
    echo '</pre>';

}
?>

I get this error:

I had a similiar issue connecting this API, but not using the libary.

This code worked for me

        $url = 'https://api.coinbase.com/v2/prices/BTC-EUR/spot';
        $response = wp_remote_get($url, array(
                'timeout' => 120,
                'headers' => array(
                    'CB-VERSION' => '2017-05-19',
                    'Accept' => '*/*',
                    'Accept-Language' => 'de-DE,de;q=0.8,en-US;q=0.6,en;q=0.4',
                    'Cache-Control' => 'no-cache',
                    'User-Agent' => 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 OPR/45.0.2552.882'
                )
            )
        );
