Shopify API getting order by name or order_number

I'm using a plugin for CakePHP to make the calls to obtain certain orders. I can call all orders with certain fields, but I was wondering how would I have to make the call to get the orders with a certain name or order_number? Here is the source for the call to Shopify. Its already authenticated and everything:

public function call($method, $path, $params=array())
    {
        if (!$this->isAuthorized())
            return;
        $password = $this->is_private_app ? $this->secret : md5($this->secret.$this->ShopifyAuth->token);
        $baseurl = "https://{$this->api_key}:$password@{$this->ShopifyAuth->shop_domain}/";
    
        $url = $baseurl.ltrim($path, '/');
        $query = in_array($method, array('GET','DELETE')) ? $params : array();
        $payload = in_array($method, array('POST','PUT')) ? stripslashes(json_encode($params)) : array();
    $request_headers = in_array($method, array('POST','PUT')) ? array("Content-Type: application/json; charset=utf-8", 'Expect:') : array();
    $request_headers[] = 'X-Shopify-Access-Token: ' . $this->ShopifyAuth->token;
        list($response_body, $response_headers) = $this->Curl->HttpRequest($method, $url, $query, $payload, $request_headers);
    $this->last_response_headers = $response_headers;
    $response = json_decode($response_body, true);

        if (isset($response['errors']) or ($this->last_response_headers['http_status_code'] >= 400))
            throw new ShopifyApiException($method, $path, $params, $this->last_response_headers, $response);

        return (is_array($response) and (count($response) > 0)) ? array_shift($response) : $response;
    }
    
    private function shopApiCallLimitParam($index)
    {
        if ($this->last_response_headers == null)
        {
            return 0;
        }
        $params = explode('/', $this->last_response_headers['http_x_shopify_shop_api_call_limit']);
        return (int) $params[$index];
    }

...and the code that makes the GET call:

// I only want the id and title of the collections
            $fields = "fields=name,id,status,financial_status,fulfillment_status,billing_address,customer";
            // get list of collections
            $custom_collections = $this->ShopifyAPI->call('GET', "/admin/orders.json", $fields);
            $this->set('collections', $custom_collections);

I think I'm missing the place where I can put the conditions for the call to get certain orders. I've already read the API documentation but can't seem to get the answer.

I've tried putting the ?name=%231001 on the url after .json to try and get the order #1001, but it brings back a empty array.

Then I tried order_number=1001 but it brings me every order with as well 1001 D: This is really confusing, Could anyone help me?

Well I found out that you can actually get the order using the name or order_number. Its another property that is not listed on the documentation for some reason. But in the URL, if your using another language, all you have to add in the GET is admin/order.json?name=%2310001&status=any this is to get the order 10001 so just add the order_number after the %23. I saw this on a forum in Shopify university, I was just implementing this wrong on my code. If your using the CakePhp shopify plugin like me all I did was add on the $field the ?name=%23". number ."&status=any";

Ill leave the code here:

    $this->layout = 'main';

$order_number = "18253";

$fields = "name=%23". $order_number ."&status=any";

$order = $this->ShopifyAPI->call('GET', "/admin/orders.json", $fields);
   if (!empty($order)) {
     $this->set('order', $order);

     } else {
       $this->Session->setFlash('<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button> No existe el numero de orden ingresado.','default',array('class' => 'alert alert-danger alert-dismissible', 'type' => 'alert'));
     }

Hope this helps someone :P
