How do I create a node using web services and Anonymous user?

Question

I have successfully installed the Services module and created a service with which I can retrieve a node or even several nodes (using Views Services) I've now configured an endpoint, whose purpose is to allow an application to create nodes through a JSON call.

After much messing about I finally configured the following JSON call:

{
"type":"demande-de-rdv",
"uid":"0",
"language":"und",
"status":"1",
"promote":"0",
"sticky":"0",
"title":"JSON Post using http_request",
"body":"Morbi sit amet leo molestie, luctus metus aliquet, pellentesque lacus! Suspendisse at laoreet nulla. Nunc sed tincidunt dolor. Donec condimentum     odio non nisl condimentum, id euismod arcu rhoncus? Nullam sit amet ante convallis, viverra nulla in, laoreet leo. Fusce vitae iaculis libero. Phasellus scelerisque varius augue, quis vulputate sapien vehicula vel. Sed at est at felis dignissim rutrum. Sed porta tristique sapien et viverra. Nunc ac elit tristique, laoreet lacus at, pharetra elit. Morbi sit amet commodo dolor? Donec consectetur justo vel fringilla rutrum"
}

However, when I post the call I get the reply "403 : Access denied for user anonymous", this despite the fact that I have configured the content type to be creatable by Anonymous (and have created a node for the content type in question to test it). I also gave Anonymous all the permissions on the Services module just in case, but it made no difference.

Where i am going wrong?

I have posted to /node and it works for anonymous after granted that permission and cleared cache by the way you don't have to set the field uid and it's not necessary if you set

$request_url = 'domain/endpoint/node';

// Node data
$node_data = array(
  'title' => 'product testing',
  'type' => 'product',
    "uid" => 0,
    "language" => "en",
    "sticky" => 0    
);
//$node_data = http_build_query($node_data);
$data = json_encode($node_data);

// cURL
$curl = curl_init($request_url);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json')                                                                       
);
curl_setopt($curl, CURLOPT_POST, 1); // Do a regular HTTP POST
curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Set POST data
curl_setopt($curl, CURLOPT_HEADER, FALSE);  // Ask to not return Header
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_FAILONERROR, TRUE);

$response = curl_exec($curl);
