Guzzle post request | WordPress.org

Hello,

I’m using Guzzle for my WP Rest application.

 "guzzlehttp/guzzle": "^7.5"

I can do the GET requests without any problems but when it comes to POST request I’m getting a

401 Unauthorized response: {“code”:”rest_cannot_create”,”message”:”Sorry, you are not allowed to create posts as this user.”,”data”:{“status”:401}}

However, when I’m doing the POST request using Postman I can make POST request without any problems

$response = $client->request('POST', '/wp-json/wp/v2/our-cruises/', [
          'json' => [
               'title' => 'This is a new test post from REST API',
               'content' => 'This is a content from REST API'
                    ]
]);
 
 
 
$body = $response->getBody();
$arr_body = json_decode($body);
print_r($arr_body);
