    'filename' => $file_name,
    'website' => $site_url,
);

// Set up the request headers
$request_headers = array(
    'Authorization' => 'Bearer ' . $doobert_api_token_value,
);

// Set up the request args
$request_args = array(
    'headers' => $request_headers,
    'body' => $request_body,
);

// Send the request
$response = wp_remote_post($curlurl, $request_args);

// Check for errors
if (is_wp_error($response)) {
    $error_message = $response->get_error_message();
    echo "Error: $error_message";
} else {
    // Handle response
    $response_code = wp_remote_retrieve_response_code($response);
    $response_body = wp_remote_retrieve_body($response);
    echo "Response Code: $response_code\n";
    echo "Response Body: $response_body\n";
}
