I've got a problem with the PayPal REST API or at least I am getting an error back using Guzzle as client.

The PHP code:

$body = [
    'name' => 'TestName982365923',
    'presentation' => [
        'brand_name'  => 'Test Name',
        'logo_image'  => 'https://example.com/site/static/public/img/paypal-logo.png',
        'locale_code' => 'DE',
    ],
];

$body_json = json_encode($body);


// New HTTP client
$client = new \GuzzleHttp\Client([
    'base_uri' => $this->getApiBaseUrl(),
    'debug' => true
]);

$options = [
    'headers' => [
        'Content-Type'    => 'application/json',
        'Authorization'   => 'Bearer ' . $this->getAccessToken(),
    ],
    'body'    => $body_json,
];


try {
    $response = $client->request('POST', 'payment-experience/web-profiles/', $options);
} catch (\Exception $e) {
    echo $e->getMessage();
    $this->setErrorMessage($e->getMessage());
    return false;
}

Returns:

When I put the same request into Paw (similar to Postman) I am getting a "HTTP/1.1 200 OK" back … with a "Webprofile ID". So I guess the problem is not my code itself, but Guzzle or my local MAMP? Is that part the main reason?
