I am getting issue while creating "Brand" feature in cs cart using cs cart API

I am using like below


$data = '{"product_features": {"28": {"feature_type": "E", "value": "test"}}}';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $URL);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_POST, TRUE);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");

curl_setopt($ch, CURLOPT_POSTFIELDS,$data);

curl_setopt($ch, CURLOPT_HTTPHEADER,$header);

// curl_setopt($ch, CURLOPT_HEADER,true);



$re = json_decode($result,true);


I am getting "product_id" in response but no feature is adding. I have checked the feature id again and it is ok. Please help me to sort the issue

Thanks in advance
