Hello,

Thank you in advance.

&nbsp;

I am trying to get the manufacturer using the API. For example

> $queryString = ‚‘;  
> &nbsp; &nbsp; &nbsp; &nbsp; if (!empty($params)) {  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $queryString = http\_build\_query($params);  
> &nbsp; &nbsp; &nbsp; &nbsp; }  
> &nbsp; &nbsp; &nbsp; &nbsp; $url = rtrim($url, ‚?‘) . ‚?‘;  
> &nbsp; &nbsp; &nbsp; &nbsp; $url = $this-\>apiUrl . $url . $queryString;  
> &nbsp; &nbsp; &nbsp; &nbsp; $dataString = json\_encode($data);  
> &nbsp; &nbsp; &nbsp; &nbsp; curl\_setopt($this-\>cURL, CURLOPT\_URL, $url);  
> &nbsp; &nbsp; &nbsp; &nbsp; curl\_setopt($this-\>cURL, CURLOPT\_CUSTOMREQUEST, $method);  
> &nbsp; &nbsp; &nbsp; &nbsp; curl\_setopt($this-\>cURL, CURLOPT\_POSTFIELDS, $dataString);  
> &nbsp; &nbsp; &nbsp; &nbsp; curl\_setopt($this-\>cURL, CURLOPT\_USERAGENT,‚Mozilla/5.0 (X11; Linux x86\_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36‘);  
> &nbsp; &nbsp; &nbsp; &nbsp; curl\_setopt(  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $this-\>cURL,  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; CURLOPT\_HTTPHEADER,  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; [  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ‚Content-Type &nbsp;: application/json;‘,  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'Authorization : Bearer '.$this-\>accessToken  
> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ]  
> &nbsp; &nbsp; &nbsp; &nbsp; );  
> &nbsp; &nbsp; &nbsp; &nbsp; $result = curl\_exec($this-\>cURL);
> 
> Also tried adding&nbsp;curl\_setopt($this-\>cURL, CURLOPT\_USERAGENT,‚Mozilla/5.0 (X11; Linux x86\_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36‘);, but still the same error and this api is working well in **postman**
